Chapter 2: Installation and Configuration 9 For cable and adapto r information, see Device Cabling on page 77. You may also use any terminal emulation program that is available on your system. 2. Configure your terminal or terminal emulation program as follows.
10 CP S Installer/Use r Guide Enter CPS New Admin Password > ***** Confirm New Admin Password > ***** After you have provided the required configura tion information, a confir mation message appears while the CPS appliance stores the va lues in its configuration database.
11 CHAPTER 3 Operations Overview The CPS serial over IP network appliance and its ports are easily co nfigured and mana ged to meet your requirements for device co nnection, user authentication, acces.
12 CP S Installer/Use r Guide Most of these settings are standard serial port operating characteristics. The CLI access character parameter specifies how you access the CLI. For mo re information, see Telnet CLI mode on p age 20. The Power parameter instructs the CCM appliance to monitor the state of a sp ecified control signal.
Chapter 3: Operations 13 that port, the display also in cludes the username, access rights and other information about the current session. When you request information about a single SPC por t, the display includes in formation configured with the SPC command.
14 CP S Installer/Use r Guide Authentication Complete Connected to Port: ... If the authentication method is co nfigured as None, you may Telnet and connect to a serial device without entering credenti als; how ever, credentials are always re quired when connecting to the CPS CLI.
Chapter 3: Operations 15 2. Issue a Connect co mmand to the desired port. CONNECT < port > 3. T o end a device session that was in itiated with a Connect command, issue a Disconnect command. DISCONNECT For more information, see Server CLI command on page 51, Connect Command o n page 43 and Disconnect Command on page 43.
16 CP S Installer/Use r Guide The PPP dial-in may be used to access a remote CPS appliance that does not warrant a WAN (Wide Area Network) link to th e Ethernet interface. In this case, th e PPP connection allows a remote PC with Telnet capability to dial th e CPS appliance and then establis h a Telnet connection to a port.
Chapter 3: Operations 17 Telnet access on port 3007, t hen port 3107 will be a direct SSH connecti on for port 7. When SSH is enabled, Telnet port 23 connec tions will be accepted from other c lients if the Server Security command includes the Encr ypt=SSH,None parameter, which in dicates that both SSH and plain text connections will be allowed.
18 CP S Installer/Use r Guide A user’s access rights are determin ed from the authentication method used. SSH key authentication always uses the access rights from the local user database.
Chapter 3: Operations 19 and the FTP connectio n will be closed. The CPS appliance then stores the SSH key with the username in the CPS u ser database. • When using the KEY keyw ord to specify the SSH key , the KEY parameter specifies the actual uuencoded SSH key .
20 CP S Installer/Use r Guide If you enable SSH connections using the Serv er Security command with the Encrypt=SSH parameter, plain text Telnet con nections will be disabled. However, if you en able SSH connections with the Server SSH command, both plain text and SSH connections wil l be allowed.
Chapter 3: Operations 21 If you initiated the device session with a Connect command, enter CLI mode and issue a Disconnect command. DISCONNECT - or - Allow the port to tim e-out due to inactivity. In this case, a notification message is issued and the serial CLI session returns to CLI mode.
22 CP S Installer/Use r Guide A server-level preemption level ma y also be configured with the Server CLI command. This value is used when authentication is disabled on the seri al CLI port and a user on that port attempts to connect to another port that is already in use.
Chapter 3: Operations 23 For more information, see Conn ecting to devices using SSH on page 16, Access rights and levels on page 23 and U ser Set command on page 72.
24 CP S Installer/Use r Guide Access levels When you specify a user’s access rights, you ma y ei ther specify the individual rights or you may use a shortcut that specifies an access level.
Chapter 3: Operations 25 • Secure indicates authenticati on will be locked to one DSV i ew software server after a successful initial access, and DSV iew software se rver and appliance cred entials will be stored on the CPS appliance.
26 CP S Installer/Use r Guide Authentication of serial CLI port sessions Using the Server CLI comman d, you may enable or di sable user authentication at the serial CLI port. You may also configure a preem ption level that will be used by a serial CLI port user when user authentication is disabled on that port.
Chapter 3: Operations 27 You must specify the server’s IP address, the UDP port to be used and a “secret” to be used. You must also specify a user-r ights attribute value that matches a v alue in the RADIUS server’s dictionary. You may also use this command to delete a RADIUS server definition.
28 CP S Installer/Use r Guide configure a lock-out perio d of from 1-99 hours. Specify ing a lock-out period of 0 disables the feature; that is, users will not be locked-ou t.

PORT HISTORY> s -u “Abort Process” The following command searches the history buffer for the string Process, ignoring case.
30 CP S Installer/Use r Guide • If Auto is specified, the number of bytes in the history buffer is displayed and the entire con- tent of the buffer is output to the T el net session. In this mode, t he history buffer’ s content may be reviewed in the T elnet client’ s scrol ling window .
Chapter 3: Operations 31 For more information, see Server SNMP command on page 58. T o specify SNMP community names: Issue a Server SNMP Communi ty command, using the Readcomm, Writecomm and Trapcomm parameters to speci fy community names.
32 CP S Installer/Use r Guide 2. T o disable SNMP traps, issue a Server SN MP T rap command with the Disable parameter . SERVER SNMP TRAP DISAB LE The CPS appliance will display a numbered list of traps that are curr ently enabled with a prompt requesting you to select trap(s) to disabl e.
Chapter 3: Operations 33 PORT < to_po rt > ALERT COPY < from_port > At the confirm ation prompt, press Y to confirm or N to cancel. When the copy operation occurs, all previously defined strings on the port being copied to will be replaced.
34 CP S Installer/Use r Guide.
35 CHAPTER 4 Using CPS Appliance Commands Accessing the CLI You may access the CLI in three ways : using the Teln et CLI, using the serial CLI or entering the CLI access character during a sessi on to a serial device.
