System Issues 21 Software Changes and Corr ec tions at 8.0.0 The following system issues and known problems have been corr ec ted at this release: ■ IP RIP cannot be set to active unless IP routing is enabled . ■ IP icmpRouterDiscovery cannot be enabled unless IP routing is enabled.
22 LAN PLEX ® 6000 E XTENDED S WITCHING S OFTWARE ■ Roving Analysis frames over a r emote F ast Ethernet connection are truncated if greater than 1495 bytes. ■ ESMs do not suppor t IGMP snooping . IP multicast traffic should be filtered using a packet filter to avoid unwanted traffic.
Known Problems 23 you do this, however , the system fails when you attempt to remove one of the inter faces. In the following example , the FDDI and the Ethernet inter faces both hav e class B IP addresses, and both have the same subnet mask: FDDI inter face 158.
24 LAN PLEX ® 6000 E XTENDED S WITCHING S OFTWARE SNMP MIB F iles SNMP MIB files are shipped with the LANplex system software as ASN.1 files on one of the software diskettes. Copies of ASN.1 files are provided f or each of the suppor ted compilers described at the end of this section.

A IP M ULTICAST R OUTING This appendix describes how to set up your LANplex® system to use IP multicast routing . Before you define any IP multicast interfaces, you should have previously defined IP int er faces and routes as described in the LANplex® 6000 Extended Switching User Guide .
A-2 A PPENDIX A: IP M ULTICAST R OUTING Enabling and Disabling DVMRP DVMRP is the simple Distance V ector Multicast Routing Protocol, similar to the IP Routing Information P rotocol. Multicast routers exchange distance vector updates that contain lists of destinations and the distance in hops to each destination.
Administering IP Multicast Interfaces A-3 When you select the IGMP option, the inter face prompts y ou to enable or disable IGMP snooping mode and IGMP quer y mode. Both are enabled by default. Under most conditions, IGMP snooping mode and IGMP quer y mode should remain enabled .
A-4 A PPENDIX A: IP M ULTICAST R OUTING Rate Limit The rate limit determines how fast multicast traffic can trav el over the inter face in kilobytes per second . Multicast traffic may not exceed this rate limit or the LANplex system will drop packets in order to maintain the set rate.
Administering IP Multicast Interfaces A-5 Disabling Multicast Inter faces T o disable multicast routing on an inter face: 1 F rom the top level of the Administration Console , enter : ip multicast interface disable 2 Enter the index number of the inter face y ou want to disable.
A-6 A PPENDIX A: IP M ULTICAST R OUTING Administ ering Multicast T unnels A multicast tunnel allows multicast packets to cross several unicast routers to a destination router that supports multicast. A tunnel has two end points. The local end point is associated with an inter face on the LANplex router .
Administering Multicast Tunnels A-7 Defining a Multicast T unnel T o define a multicast tunnel: 1 F rom the top level of the Administration Console , enter : ip multicast tunnel define 2 Enter the index number(s) of the inter face(s) with which y ou want to associate a multicast tunnel.
A-8 A PPENDIX A: IP M ULTICAST R OUTING Displaying Routes T o display all available routes in the IP multicast routing table: 1 F rom top level of the Administration Console , enter : ip multicast routeDisplay The DVMRP and IGMP status appear on the screen.
Displaying the Multicast Cache A-9 Displaying the Multicast Cache The multicast cache contains the IP source address and destination addr ess for packets obser ved on the system. The multicast cache shows you how information is routed o ver inter faces and ports in your system.
A-10 A PPENDIX A: IP M ULTICAST R OUTING Example: Enter multicast source address [131.188.0.0] Enter multicast group address [244.2.0.2] DVMRP is enabled, IGMP snooping is enabled The following displa y shows the multicast cache configuration: Multicast Routing Cache Table (125 entries) Origin Mcast-group CTmr Age PTmr In-If Out-Ifs >202.
Displaying the Multicast Cache A-11 T able A-2 describes the fields in the CacheDisplay . T able A-2 Information in the CacheDisplay Field Description Origin The source of the incoming packets. Entries preceded by an angle bracket (>) indicate a multicast subnet.
