Chapter 1. Getting Started This chapter shows you how to get started with using the following components related to the IBM 2210 Nways Multiprotocol Router (2210) and the Multiprotocol Routing Service.
Local Consoles Local consoles are either directly connected by an EIA 232 (RS-232) cable, or connected via modems to the router . Y ou may need to use a local console during the initial software installation. After the initial setup connection, you can connect using T elnet, as long as IP forwarding has been enabled.
Remote Consoles Remote consoles attach to the router using a standard remote terminal protocol. Remote consoles provide the same function as local consoles, except that a local console must be used for initial configuration if your IBM 2210 was not pre-configured at the factory .
Y ou may have to press the Enter key more than once or press Ctrl-P to obtain the * prompt. Once at this level, you can begin to enter commands from the keyboard. Press the Backspace key to delete the last character typed in on the command line. Press the Delete key or Ctrl-U to delete the whole command line entry so that you can reenter a command.
Discussing the User Interface System The software (Multiprotocol Routing Services) is a multitasking system that schedules use of the CPU among various processes and hardware devices.
Figure 2 is an example of the relationship between the various process levels. Note: Also shown in Figure 2 are the various commands to access each process level and return from each process level.
Chapter 2. Using the Software This chapter describes how to use the software. It consists of: v “Entering Commands” v “Connecting to a Process” v “Some Configuration Suggestions” on page .
2. Use the talk pid command, where pid is the number of the process to which you want to connect. (For more information about these and other OPCON commands, refer to “Chapter 3. The OPCON Process” on page 25.) Note: Not every process listed has a user interface (for example, the talk 3 process).
STATUS of process(es) TALK to process TELNET to IP-Address Exiting a Lower Level Environment The multiple-level nature of the software places you in secondary , tertiary , and even lower level environments as you configure or operate the 2210. T o return to the next higher level, enter the exit command.
4. Configure any base services, such as boot options. Access the configuration process as described in “Accessing the Configuration Process, CONFIG (T alk 6)” on page 14. 5. Configure the interfaces. Access the interface configuration process as described in “Accessing the Network Interface Configuration Process” on page 15 .
2. Retrieve the configuration from the 2210 on which you want to base the new configuration. 3. Make the changes you need for the new configuration. These changes include addresses, the host names, users, and other items. 4. Save the configuration with a different name from the name that you used to retrieve the configuration.
v The configuration process to initially configure and enable the interface, feature, or protocol, as well as perform later configuration changes. v The operating/monitoring process to display information about each interface, feature, or protocol, to make temporary configuration changes, or to activate configuration changes.
Accessing the Operating/Monitoring Process, GWCON (T alk 5) T o view information about the interfaces, features, or protocols or to change parameters while running, you must access and use the operating (monitoring) process. Operating command interfaces are modes of the GWCON interface.
The following example adds a dial circuit interface: Config> add device dial-circuit Enter the number of PPP Dial Circuit interfaces [1]? Adding device as interface 8 Base net for this circuit[0]? .
Note: Not all network interfaces are user-configurable. For interfaces that cannot be configured, you receive the message: That network is not configurable Displaying the Interface Configuration: From the same interface configuration prompts, you can list configuration information specific to that selected interface by using the list command.
T able 2. Network Architecture and the Supported Interfaces (continued) Network Architecture Supported Interfaces Dial-In A PPP dial circuit interface that has configuration parameters defaulted to support DIALs Multilink PPP (MP) Supported on any PPP link L2TP Supports virtual PPP DIALs connections through the Layer 2 T unneling Protocol (L2TP).
+ network 2 X.25> In this example, the X.25 console prompt is displayed on the console. Y ou can then view information about the X.25 interface by entering the X.25 console commands. Monitoring the Network Interface: Refer to the specific chapters in this manual for complete information on monitoring your 2210’s network interfaces.
1. At the CONFIG> prompt, enter the list configuration command to see the numbers and names of the protocols purchased in your copy of the software.
or + protocol IP The protocol console prompt then displays on the console. This example shows the IP protocol console prompt: IP> Y ou can now begin entering the protocol’s commands. See the corresponding protocol section of the Protocol Configuration and Monitoring Reference for more information on specific protocol console commands.
Repeating a Series of Commands in the Command History There is an additional feature for advanced users to facilitate repeating a particular series of GWCON or CONFIG commands. C1, C2,...,Cn in the Command History is referred to as a repeat sequence .
ELS config> Ctrl-N for NEXT to retrieve the next command in sequence- ELS config>exit Enter Config> Starting a Repeat Sequence After All Commands Are Entered On the other hand, if you first enter C1, C2, ... Cn, and retrieve C1 via Ctrl-B or Ctrl-F .

Y ou can configure more than one boot file in the boot configuration database by specifying the path and name of each boot file (using the add command described on page “Add” on page 94).
A Device as a BOOTP Relay Agent If BOOTP request requires multiple hops before reaching the BOOTP server , the BOOTP relay agent routes the packet via IP to all BOOTP servers that it knows about.
constructs a BOOTP reply and adds the client’s IP address, along with the location of the Boot server and boot filename. If a match does not occur , the packet is dropped.
2. Configure IP so that the device can reach each host with the archived configuration. The Protocol Configuration and Monitoring Reference explains the IP configuration commands. v The source IP address for TFTP transfers is the device ID. This ID, by default, is a configured IP address for one of the device’s network interfaces.
The router accepts any printable ASCII character as part of the file name definition, with two exceptions: v The file name cannot begin with a numeric character v The file name cannot contain a RETURN or LF (line feed) character .
Loading an Image at a Specific T ime There may be occasions when you may want to load an image into a device on a specific day and time when you will be unavailable. Y ou can configure the device to perform a timed load using the timedload activate command .

can configure more than one boot device. Obtain the loadname using the list ibd command. The loadname is case-sensitive. Example: add boot-entry remote host or IBD loadname [0.0.0.0]? 128.185.30.0 via gateway (0.0.0.0 if none) [0.0.0.0]? 0.0.0.0 timeout in seconds [3]? 10 file name [ ]? loads/Y21.
dump-entry Specifies the IP address of the remote host that will receive the dump file(s). When you enter the add dump-entry command, you must supply the following information: remote host? IP addre.
change address Change which entry [1]? 1 Which interface is this address for [0]? 1 New address [192.9.1.1]? 128.185.162.1 Net mask for this interface [255.255.255.0]? boot-entry Modifies the configuration about a previously added network boot file.
Copy Use the copy command to copy boot files and configuration files to and from remote routers and hosts. T o use the copy command, the device must have IP configured and running on at least one interface. The device cannot be in Config-only mode.
[ibd or filename ] Copies a boot file or configuration file from an IBD. Y ou must include the file name. [ host-ip-address or filename ] Copies a boot file or configuration file from a remote host. Y ou must include the file name. Delete Use the delete command to remove entries from the boot and dump configuration database.
When you enter the delete dump-entry command, a prompt appears for the entry you want to delete. The dump entry number is the first number that appears on each line when you enter the list dump-entries command at the Boot config> prompt. T o verify the deletion, use the list command.
list all command to verify the dump settings. Dumping is suppressed until you enter the enable dumping command. Disable dumping is the default setting. unique-naming Suppresses the automatic unique naming of dump files. After entering this command, use the Boot CONFIG list all command to verify the unique naming settings.

Chapter 1 1. The Messaging (MONITR - T alk 2) Process This chapter explains how to collect and display messages. (Refer to “Chapter 12. Using the Event Logging System (ELS)” on page 147 for information about ELS and message formats. Refer also to the IBM Nways Event Logging System Messages Guide for a description of each message.
T o specify a default device for MONITR, define the device in Static RAM by using the CONFIG set logging disposition command. Specifying a default device is useful if you have a terminal set up to print.
Chapter 12. Using the Event Logging System (ELS) This chapter describes the Event Logging System (ELS). The ELS continually logs all events, filtering them according to parameters that you select. A combination of operational counters and the ELS provides information for monitoring the health and activity of the system.
Entering and Exiting the ELS Configuration Environment The ELS configuration environment (available from the CONFIG process) is characterized by the ELS Config> prompt. Commands entered at this prompt create the ELS default state that takes effect after you restart the router .

v Use the IBM Nways Event Logging System Messages Guide to determine which messages are not normal. When initially viewing ELS from the MONITR process, you will see a considerable amount of information. Because the router cannot buffer and display every packet under moderate to heavy loads the buffers are flushed.
Y ou can also use remote logging instead of capturing ELS output on a UNIX Host. For more information about remote logging, see “Using and Configuring ELS Remote Logging” on page 155.

Configuring the 2210 for Remote Logging T o configure a 2210: 1. In talk 6, configure the remote-logging facility as shown in Figure 7 on page 158. The IP address specified as the source-ip-addr s.
the name server at least responds quickly with “address not found.” T o determine whether this happens, issue the host command on your workstation as follows: workstation> host 5.1.1.1 host: address 5.1.1.1 NOT FOUND workstation> If the response takes more than 1 second, select an IP address which resolves more quickly .
Remote Logging Output Figure 9 on page 160 shows a sample from the /tmp/syslog_news_info file. Notice that the first message has a sequence number of 310.
v A route from the source 2210 to the remote workstation was not in the routing table v The interface for the outbound UDP packet containing the ELS messages was not in the “Up” state Notice in 1 that messages 31 1-313 did not get remote-logged.
Y ou can use the timestamp, which appears in both the remote-logging output file and the talk 2 output, to determine when the first ELS message is successfully remote-logged. T o use the timestamp for this purpose, configure ELS such that the timestamp in the monitor queue displays the time-of-day .
3. Use the net number from the previous step to determine the associated MAC address 4. In talk 6, add an ARP entry to establish a static IP address to MAC address relationship Additional Consideratio.
Duplicate Logging If a facility value is repeated in syslog.conf , for example: user.debug /tmp/syslog_user_debug user.alert /tmp/syslog_user_alert The syslog daemon will log user .

Chapter 20. Overview of LAN Emulation Note: See the glossary for definitions of the acronyms and terms used in this chapter . The IBM 2210 implements the LAN Emulation Over A TM: V ersion 1.0 Specification which is widely accepted as the industry standard for multivendor multiprotocol interoperability .
The network management benefits of emulated LANs (ELANs) come from increased flexibility in handling moves, adds, and changes. Membership in an ELAN is not based on physical location; instead, logically-related stations are grouped to form an ELAN (stations can also be members of multiple ELANs).
Broadcast and Unknown Server (BUS) A LAN emulation service component responsible for the delivery of multicast and unknown unicast frames. The LES, BUS, and LECS are collectively referred to as the LE service components. Each ELAN has a dedicated LES and BUS.
End stations obtain their Network Prefix from the switch and form their own addresses by appending an ESI and selector . These addresses must then be registered with the switch, which rejects the registration if the A TM address is not unique. ESI Each A TM interface on the router has a universally administered, or burned-in, MAC address.
explicit assignment; by default, 200 of the 256 possible selectors per ESI are reserved for explicit assignment. Run-time selector assignment is beneficial when you do not need to control the assigned selector , for example, when you are configuring clients in Classical IP that are not paired with an ARP server .
Overview of the LECS Function LE clients are not required to use the LECS, although it is recommended. If the LECS is not used, each LE client must be configured with the A TM address of the LES that serves its ELAN.
This field can specify the upper bound on the size of a data frame that can be processed by the LE client, or it can be unspecified. The LECS cannot assign a client to an ELAN with a maximum frame size larger than that specified by the client. If the ELAN allows frames too large for the client to handle, the client cannot function on that ELAN.
Sample Situations for Use of the LECS Assignment Policies The following section offers examples of various LECS assignment policies. A TM Address Policy The LECS permits two types of A TM address policy values. The first type is a variable length A TM address prefix.
This setup requires configuring the LE clients with the correct ELAN Name. v Use names for the LE clients Each LE client can be given its own name. For example, you could create the policy values (Joe, LES_A) and (Mary , LES_A). Then, the LE clients configured with these names would be directed to the same LES.
v By default, ELANs use best-effort connections to connect to the BUS. For ELANs where BUS traff ic is heavy , better performance can be obtained by using reserved bandwidth connections to the BUS. The characteristics of the Multicast Send VCC between the LE client and the BUS can be controlled with TL Vs.
Address Registration LE clients register LAN destinations with the LES to ensure uniqueness and to allow the LES to answer LE_ARP_REQUEST s, which LE clients issue to learn the A TM address associated with a particular LAN destination.
This list is provided to help you clarify the A TM connections that are established between the LE client and the BUS: Multicast Send VCC (bidirectional point-to-point) From LE client to BUS Multicast Forward VCC (point-to-multipoint) From BUS to LE client BUS Functions The BUS has two basic functions: 1.
BUS processing requirements are increased and multicast frames must be transmitted twice (once on each Multicast Forward VCC). In general, IBUS operation is recommended; however , this option should be disabled in configurations that have source route bridges that join the ELAN as non-proxies.
v LE clients that include the proxy function to provide bridging support forward the broadcast frame on to other LAN segments. v All end stations receive and process every broadcast frame.
With BCM IPX enabled, any quiet device (that is, a device that does not transmit IPX advertisements) that needs to receive IPX advertisements has to be configured as a BCM static target. An example of such a device is a station running software that discovers the IPX network topology by monitoring IPX advertisements.
Note: Broadcast Manager and Source Route Management are unavailable and cannot be enabled if bus-mode is set to adapter . LAN Emulation Reliability A perceived lack of robustness has been one of the most widely proclaimed criticisms of LAN emulation.
The LECS retains a short-term memory of all client assignments so that it can alternately direct an LE client to a primary and backup LES. This simple heuristic makes the correct assignment in the nominal case of no failure and is self-correcting. At worst, the heuristic causes the LE client to repeat the configuration phase of joining an ELAN.
1. At the LECS, use A TM addresses to assign clients to the LES. See “Overview of the LECS Function” on page 260 for more information. 2. Activate the LECS Interface on the router . 3. Activate the security option of the LESs. 4. Activate LECS Access Controls for any A TM address prefixes that should not be allowed to access the LECS.
Chapter 21. Using A TM This chapter describes how to use the A TM interface. It includes the following sections: v “A TM and LAN Emulation” v “How to Enter Addresses” v “A TM-LLC Multiplexin.
This information applies to addresses entered for A TM; LAN emulation; Classical IP and ARP over A TM; and IPX and ARP over A TM. A TM-LLC Multiplexing Protocols that run natively over an A TM interface can use A TM-LLC multiplexing to share A TM addresses and both SVC and PVC channels between users.
interfaces that can be created depends on the data packet size for the interfaces and is limited to a maximum number of 253 per router . The use of A VIs significantly improves the configuration options for protocols such as IPX that are limited to one instance or address per A TM interface.
Note: Because all resources are shared among the ARI and all its A VIs, an ESI added on an ARI is automatically available to all A VIs configured on the ARI. Y ou should not assign the same ESI and selector combination to two different protocol clients using the same ARI even though they are configured on different A VIs.

limit. The default value should be satisfactory in most situations. An example of a situation where it is beneficial to change this value would be if the majority of the stations use 25–Mbps adapters.
Each ESI can have up to 255 associated selectors (0x00 through 0xff). The range of selectors is partitioned into two subranges, a configured selector range and an automatically assigned selector range. The A TM interface parameter max-configured-selector gives the upper bound on the configured selector range.
Example: ATM INTERFACE> set max-mp-parties 300 trace Sets the packet tracing parameters on the interface. Packet tracing can be enabled or disabled on a range of VPI/VCI values. Common VPI/VCI values to trace are: v 0/5 for signalling packets v 0/16 for ILMI packets.

Configuration Information X.25 recognizes an incoming call for XTP based on the node addresses configured for XTP . Therefore, in order to transport X.25 traff ic between the X.25 nodes, you must configure X.25 to map to the data terminal equipment (DTE) address and IP addresses of the routers to which the nodes are connected.

or “*”. The special case of a DTE address of “*” represents any DTE address, even a null address. The null address is useful for handling incoming calls with no calling address in the X.
This causes the search for the remote DTE to proceed to the next router in the peer router list. If a pass through the list of peer routers is completed without a successful connection through any of the peer routers, the call to the local DTE is cleared.
Configuring XTP XTP is a protocol forwarder used to transport X.25 traf fic over TCP/IP . XTP allows existing X.25 devices to communicate over a TCP/IP backbone and migrate from an X.25 network to a network of your choice. Configuration Procedures This section defines the detail for configuring the network displayed in Figure 20.

Chapter 30. Using Frame Relay Interfaces This chapter describes how to use the Frame Relay interface and includes the following sections: v “Frame Relay Overview” v “Frame Relay Network Manageme.
Frame Relay Network The FR network consists of the FR backbone (consisting of FR switches provided by the FR carrier) providing the FR service. The router functions as the FR connection device. The router encapsulates FR frames and routes them through the network based on a Data Link Connection Identifier (DLCI).
v Preserves the ordering of frame transfer on individual VCs v Does not acknowledge or retransmit frames Frame Relay Switched V irtual Circuits Frame Relay Switched Virtual Circuits (SVCs) provide the ability to implement ″ cut-through ″ routing in a Frame Relay network, minimizing or eliminating intermediate router hops between DTEs.
end-to-end PVC connection is not established. Router B receives an inactive status for that PVC. When the LMI and SVCsare disabled, the FR interface is running on a serial line and a DTE cable is being used, the FR protocol asserts the DTR and RTS modem control signals.
By enabling orphan circuits, you allow the router to forward packets over circuits you did not configure. Packets that would normally be dropped are now forwarded. An orphan switched virtual circuit is an SVC that is not configured for your router but is created when a call-in is received for it.
If multiple PVCs are required and are not in a PVC group, the interface is not activated until all required PVCs are active. If a required PVC belongs to a PVC group, the Frame Relay interface becomes inactive when all PVCs in the PVC group are inactive.
Command/Response (C/R) This field’s use is not defined within the Frame-Relay standards and the field is passed transparently across the network. Extended Address This version of FR does not support extended addressing.
Frame Forwarding over the Frame Relay Network When the FR protocol receives a packet for encapsulation, it compares the packet’s network address to the entries in the Address resolution Protocol (ARP) cache.
Multicast can also be enabled or disabled for an individual SVC. Use the multicast option on add switched-virtual-circuit . Frame Relay Network Management The supplier of the FR network backbone provides FR network management.
The PVC status information element contains the following information: the local DLCI number for the particular PVC; the state of the PVC (active or inactive); and whether the PVC is new or an existing PVC that management already knows about.
switched-virtual-circuit configuration command. Y ou can also dynamically change the CIR with the set circuit console command. Y ou can also set the default CIR for all Frame Relay circuits on this interface using the set CIR-defaults command. Some Frame Relay switches allow a value of 0 to be configured for CIR.
The network delivers this excess data with a lower probability of success than committed burst size data. Set the Be to a value greater than zero only if you are willing to accept the risk of discarded data and its effect on higher-layer protocol performance.
If the CIR monitoring feature is not enabled the maximum information rate is equal to the line speed. V ariable Information Rate The variable information rate (VIR) ranges from the configured minimum IR to the calculated maximum IR when the CIR monitoring or congestion monitoring features are enabled.

for all VCs to relieve congestion. Enabling the throttle-transmit-on-fecn parameter , along with either the CIR or congestion monitoring options, causes the device to treat a FECN like a BECN thus reducing overall FR network congestion when any congestion notification is received.
v A long-term condition, the Frame Relay protocol will set the transmit rate for the affected PVCs to the calculated minimum information rate. v Facility or equipment failure or maintenance action, or.
v Configure FR destination addresses. If you are running a protocol such as IP or IPX over the FR interface, and are interconnecting with devices not supporting the Address Resolution Protocol (ARP) or Inverse ARP on FR, use the add protocol-address command to add the static protocol and address mapping.

Chapter 32. Using Point-to-Point Protocol Interfaces This chapter describes how to use the Point-to-Point Protocol for interfaces on the device. Sections in this chapter include: v “PPP Overview” .
PPP currently supports the following control protocols: v AppleT alk Control Protocol (A TCP) v DECnet Protocol Control Protocol (DNCP) v Banyan VINES Control Protocol (BVCP) v Bridging protocols (BCP.
Flag Fields The flag field begins and ends each frame with a unique pattern of 0 111111 0 . Generally a single flag ends one frame and begins the next. The receiver attached to the link continuously search for the flag sequence to synchronize the start of the next frame.
1. Before exchanging any network layer datagrams, PPP first opens the connection through an exchange of LCP configuration packets. As part of this negotiation process, the PPP processes at each end .
LCP Packets LCP packets are used to establish and manage a PPP link and can be loosely divided into three categories: v Link establishment packets that exchange configuration information and establish the link. v Link termination packets that shut down the link or signal that a link is not accepting connections at a particular time.
establishment type packets that LCP defines. They may implement some of the additional LCP packet types, and they also may define additional packet types beyond what LCP uses. Unlike LCP packets, the structure of an NCP frame may be modified according to options negotiated by LCP during the link establishment phase.
Protocol-Reject LCP packet code field is set to 8. The transmission of this packet type indicates that a PPP frame has been received that contains an unsupported or unknown protocol (the PPP “protocol” field was unrecognized for some packet).
There are different authentication protocols in use: Password Authentication Protocol (P AP) and Challenge/Handshake Authentication Protocol (CHAP). Microsoft PPP CHAP (MS-CHAP) is also available to authenticate Windows workstations and peer routers. P AP and CHAP are described in detail in RFC 1334, and briefly described later in this section.
Challenge-Handshake Authentication Protocol (CHAP) The Challenge-Handshake Authentication Protocol (CHAP) is used to periodically verify the identity of the peer using a three-way handshake. This is done upon initial link establishment, and may be repeated anytime after the link has been established.
Configuring PPP Authentication The following sections describe configuring PPP authentications for two situations: v Configuring the 2210 to authenticate a remote device. v Configuring the 2210 to be authenticated by a remote device. These two situations are independent.
Attention: Do not use the following commands unless you want the device to perform authentication as described in “Using Local or Remote Authentication” in Using and Configuring Features . v enable pap v enable chap v enable spap Note: SP AP is only available on interfaces that have IBM DIALs Dial-In circuits configured.
PPP User Name: no callback Type: Single User User IP Address: Interface Default SubNetMask: 255.255.255.255 Hostname: <undefined> Time-Alotted: Box Default Call-Back Type: Not Enabled Dial-Out: .
v APPN Intermediate Session Routing Control Protocol (APPN ISRCP) AppleT alk Control Protocol A TCP is specified in Request for Comments (RFC) 1378. IBM’ s implementation of A TCP supports the AppleT alk-Address option. The implementation supports both full router mode and half router mode.
IP Control Protocol IPCP is specified in RFC 1332. IBM’ s implementation supports the following options: v V an Jacobsen IP Header Compression as described in RFC 1 144. v IP Address The router can send its IP address, as well as accept an IP address, from a peer , or supply an IP address to a peer , if requested.
The router automatically adds a static route directed to the PPP interface for the address that is successfully negotiated, allowing data to be routed properly to the dial-in client. When the IPv6CP connection is ended for any reason, this static route is subsequently removed.
v The client configuration controls the suspension and resumption of a VC. The DIALs server cannot control that aspect of the connection. v A VC can be established through an MP bundle. v VCs cannot run over L2TP . v Suspended VCs cannot be displayed with current network management tools.

If Lower DTR is set to “enabled”, then the DTR signal will be dropped when the interface is disabled. This behavior may be desirable in situations where the interface has been configured as an al.
Use the set name command to configure the name of the 2210 if the peer router is configured to authenticate the 2210’s local name. Note: MS-CHAP is not supported on 4M V2L models.
ecp Displays the current Encryption Control Protocol state. Example: list ecp ECP Options ----------- Data Encryption enabled Algorithm list: DESE-CBC DESE (Data Encryption Standard Encryption Protocol) Data Encryption Enabled/Disabled Indicates whether data encryption is enabled or disabled on interface.
ipcp Lists the Internet Protocol control protocol options. Example: list ipcp IPCP Options ------------ IPCP Compression: None Send Our IP Address: Yes Remote IP Address to Offer if Requested: 10.0.0.3 IPCP compression Indicates whether the PPP handler accepts compressed IP headers.

list ncp NCP Parameters --------------- Config Request Tries: 20 Config Nak Tries: 10 Terminate Tries: 10 Retry Timer: 3000 Config Request T ries: Number of times NCP sends configure-request packets to a peer station while attempting to open a PPP link.
ncp... bcp Sets the Bridging Control Protocol (BCP) parameters. Example: set bcp TINYGRAM COMPRESSION [no]: Tinygram Compression Specifies whether or not T inygram Compression is used. This option is useful for protocols that are prone to problems when bridged over low-speed (64 Kbps and below) lines.
Note: Failure to detect a bad packet can cause all subsequent data to be decompressed incorrectly . This option sets the exact form of check value used. Choose one of the following: 0 None: No check value is used. Without a check value, there is no way to determine that a packet has been lost, out-of-sequence, or corrupted.
ST AC-LZS The ST AC-LZS algorithm as described in RFC 1974 MPPC The Microsoft Point-to-Point Compression algorithm as described in RFC 21 18. Example: set ccp protocols Enter a prioritized list of enabled compressors (first is preferred), all on one single line.
hdlc speed value For internal clocking, this command specifies the speed of the transmit and receive clock lines. The range is 2400 to 2 048 000 bps. For external clocking, this command does not affect the hardware but it sets the speed of some protocols, such as IPX, used to determine the routing parameters.
ipv6cp Sets the IPv6 Control Protocol option for the link. Example: set ipv6cp Send Our IP address [no]: Send Our IP address Specifies whether or not to send the local IPv6 address to the remote end of the link. Set this option to yes if the other end of the link requires the IPv6 address.
Specify a 32-bit bit mask in hexadecimal. If a bit in position ’N’ of the mask is set, the corresponding ASCII character ’N’ must be escaped (the LSB is bit number 0, corresponding to the ASCII NUL character). The default value for this option is ’0A0000’, indicating that XON and XOFF (control-Q and control-S) need to be escaped.
PPP protocol values are all assigned such that the upper byte of the protocol is an even value and the lower byte is an odd value (a limited use of the more generalized mechanism described by the ISO 3309 extension mechanism for address fields).
Notes: 1. While the “case” that you use for names and passwords sent to the peer on the link are preserved for this product, interoperability with other vendor products is easier if all names and passwords are entered in lowercase. 2. Other implementations may not handle names with the same maximum length as supported in this product.
T erminate tries Sets the number of terminate-request packets sent by NCP to a peer station to close a PPP link. The range is 1 to 100. The default value is 10. This action indicates the desire to close an NCP connection. The retry timer is started after a terminate-request packet is transmitted.

Chapter 34. Using the Multilink PPP Protocol This chapter describes how to use the Multilink PPP Protocol (MP). It includes the following sections: v “MP Considerations” on page 510 v “Multi-Cha.
MP interfaces that do not have a dedicated link must be inbound-only interfaces. These interfaces are similar to the any inbound dial circuit. The Bandwidth Allocation Protocol (BAP) and its control protocol (BACP) allow an MP interface to increase and decrease its bandwidth by adding and dropping dial circuits.
Multi-Chassis MP An MP bundle with a Layer 2 Tunnel that contains a phone hunt group that spans multiple physical Network Access Servers is known as a multi-chassis MP . Multi-chassis MP uses rhelm or user-based tunneling (see “Using Local or Remote Authentication” in Using and Configuring Features ) to establish the MP endpoint destination.

Chapter 36. Configuring SDLC Relay This chapter describes the Synchronous Data Link Control (SDLC) Relay configuration and operational commands. For further information on when to use DLSw SDLC vers.
SDLC Relay Configuration Commands This section summarizes the SDLC Relay configuration commands. Both the network and protocol parameters for SDLC relay are documented in this chapter . The SDLC Relay configuration commands allow you to specify router parameters for interfaces transmitting SDLC Relay frames.
Interface number The interface number of the router that designates the local port. Primary or Secondary Designates the port type, primary (P) or secondary (S). remote–port Identifies the IP address of the port directly connected to the serial line on the remote router .
Syntax: disable grou p... port group group# Suppresses transfer of SDLC Relay frames to or from a specific group (group#). Example: disable group 1 port Suppresses transfer of SDLC Relay frames to or from a specific local port.
Example: list Maximum frame size in bytes = 2048 Encoding: NRZ Idle State: Flag Clocking: External Cable Type: RS-232 DTE Speed (bps): 0 Transmit Delay Counter: 0 Maximum frame size in bytes Maximum frame size that can be sent over the link. The maximum frame size must be large enough to accommodate the largest frame and the 15 byte SRL Y header .
Net Number Indicates the device number of the local port. This number matches the number displayed using the Config list devices command. IP Address Indicates the IP address of the remote port. group group# Displays the configuration of a specified group.
A DTE cable is used when you are attaching the router to some type of DCE device (for example, a modem or a DSU/CSU). A DCE cable is used when the router is acting as the DCE and providing the clocking for direct attachment. clocking internal or external Configures the SRL Y link’s clocking.
The other W AN ports must be clocked at 64 Kbps or less. transmit-delay value Allows the insertion of a delay between transmitted packets. This command ensures a minimum delay between frames so that it is compatible with older , slower serial devices at the other end.
Clear-Port-Statistics Use the clear-port-statistics command to discard the SDLC Relay statistics for all ports. The statistics include counters for packets forwarded and packets discarded. Syntax: clear-port-statistics clear-port-statistics Clears port statistics gathered since the last time you restarted the router or cleared statistics.
group group# Allows transfer of SDLC Relay frames to or from the specified group (group#). port Allows transfer of SDLC Relay frames to or from the specified local port. Example: enable port Interface number: [0]? 2 (P)rimary or (S)econdary: [s]? P Interface number Indicates the interface number of the local port that you want to enable.

link Allows subsystems in the router (for example, DLSw) to use SDLC’s facilities. station name or address Allows connections to the specified secondary remote end station (link station name). List Use the list command to display configuration information on one or all SDLC link stations.
Group Poll Address used for the group poll feature for multipoint link configurations. Secondary stations having group inclusion coded as yes will respond to unnumbered polls received from this address. This address must be non-null for the group poll feature to be in effect for any secondary stations under this link.
SNRM The maximum number of times the router will send an SNRM(E) frame without receiving a response before timing out. A value of 0 indicates that the router will retry indefinitely . Poll retry The maximum number of times the router polls the station without receiving a response before timing out.

T able 83. Dial Circuit Configuration Commands Summary (continued) Command Function Set Configures the dial circuit for inbound or outbound calls, maps the dial circuit to a serial line interface, and sets addresses, idle timeout, priority , lid_out address, inbound destination, and self-test delay .
Be aware that you cannot configure HDLC parameters of the dial circuit configuration when you configure PPP or Frame Relay for ISDN. Physical layer parameters are configured on the ISDN interface. For information on configuring the PPP protocol, refer to “Chapter 25.
Bandwidth Displays the bandwidth value in Kbps. Base net Displays the name of the serial line interface to which this dial circuit is mapped. Callback Displays the setting of this option.
Notes: 1. If you are running SDLC, I.430, I.431, Channelized, or X.25 on a dial circuit, you will be unable to use the set command to change the following parameters as the software will use specific.
For Channelized: 56 or 64 Default value: 64 callback [ Ye s or No ] The callback feature uses the callers telephone number to verify the call against an authentication table and then disconnects the incoming call. Callback then makes an outgoing call to the same caller .
lid_out_addr address_name The lid_out_addr is the name of a dial circuit between two routers. When more than one circuit is configured between two routers (parallel circuits), then there needs to be a way to unambiguously know which dial circuit connects between them.
Note: Y ou can only use this parameter for Channelized T1/E1 circuits. V alid values: For Channelized T1: 1 to 24 For Channelized E1: 1 to 31 Default value: None Example: set timeslo t1458 Dial Circuit Monitoring Commands T able 84 describes the dial circuit monitoring commands.
