LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE REVISION 8.0.2 Overview Hardware Dependencies These installation instructions and release notes describe revision 8.0.2 of the LANplex 6000 Extended Switching software from 3Com Corporation, dated December 2, 1996. This revision supersedes revision 8.0.1, dated November 13, 1996. LANplex Intelligent or Extended Switching software revision 8.0.2 requires an LMM+ module at revision 1.21 or greater (for revision 1 modules) or revision 2.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE Extended Switching Software Requirement Release 8.0.0 or greater of Extended Switching Software requires a minimum of 2 MB of memory on Ethernet/FDDI Switching Modules (EFSMs). Memory configuration may vary. If you have an EFSM with 1 MB of memory, you can order a memory upgrade. Contact your sales representative.
Updating Your System Software 7 CAUTION: The FSM module requires LANplex system software revision 8.0.0 or later and LMM+ revision 1.21 or greater (for revision 1 modules) or revision 2.12 or greater (for revision 2 modules). See “Upgrading Your LMM or LMM+” on page 5. The menu item ip forwarding was changed to ip routing at release 7.0.0. If you have created automated scripts that include ip forwarding, you must edit these scripts to reflect this change.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE Copying System Software to a Hard Disk You can copy system software to a system that has either a UNIX or an MS-DOS operating system. Copying to the UNIX® Platform The LANplex software for a UNIX system is distributed on five diskettes. Diskettes #1, #2, #3 and #4 contain the LANplex software. Diskette #5 contains the SNMP MIBs. To copy the software to a UNIX hard disk, follow these instructions.
Updating Your System Software 9 8 Insert diskette #4 containing the LANplex software file into the disk drive and extract the fourth part of the file using the following command: tar xvf /dev/rfd0 9 Remove diskette #4 using the following command: # eject The following files should be in your /usr/lp6000R directory: ■ README1 ■ lp6000R00 ■ lp6000R01 ■ lp6000R02 ■ lp6000R03 ■ restore_lpxR 10 Use the supplied script to decompress and restore the split file (lp6000R00, lp6000R01, lp6000R02, and
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE 3 At the command line in the Setup dialog box, enter a:setup and click OK. A Welcome screen appears. You are prompted to continue or to cancel the installation. To continue, click Next. To cancel the installation and exit the Setup program, click Cancel. You will be guided through the rest of the installation procedure by the Install Shield Wizard. This procedure creates a file folder called lp6000r, which contains: ■ IMAGE folder ■ MIBS folder ■ README.
Updating Your System Software Loading System Software on the LMM+ 11 Before loading the system software on the LMM+, verify that the host computer, which has a copy of the updated system software, is connected to the LANplex 6000 system. You can load the system software into flash memory while the system is operating. You do not need to bring the system down. After the flash install is completed, a quick reboot puts the newly loaded software to use.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE Example of the software installation prompts. Host IP address [192.9.200.14]:192.9.200.96 Install file pathname [/usr/lp6000R/lp6000R]: User name: ronnyk Password: After the software is loaded, this message appears: Installation complete. If the LANplex executable software image stored in flash memory is corrupted (for example, when a power failure occurs while you are updating software), contact 3Com Technical Support.

LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE Software Changes and Corrections at 8.0.1 What’s New at Revision 8.0.0? New Features The following system issues and known problems have been corrected at this release: ■ The FSM’s Port Status LEDs no longer light yellow after diagnostics have run on the system when the port’s FDDI MAC was assigned to the internal FDDI backplane path. ■ A LANplex IP interface now responds to ping requests up to an MTU size of 4,352 bytes.
What’s New at Revision 8.0.0? 15 LANplex Extended switching software 8.0.0 or greater requires 2 MB EFSMs. The EFSM TP-DDI module does have 4 MB of memory, although its lower ejector tab label is blank. See “Extended Switching Software Requirement” on page 6. Support for RMON Revision 8.0.0 or greater of LANplex software offers Full-Time Embedded RMON support for Ethernet and Fast Ethernet ports through SNMP for four RMON Groups.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE RMON MIB Support Added. RMON MIB support has been added for: ■ Statistics ■ History ■ Alarm ■ Event State Field Added to the Interface Display A new field, state, has been added to the interface display table, allowing you to view the state of all interfaces configured for each switching module in the system. The interface state is determined based on the state of all ports associated with the interface.
What’s New at Revision 8.0.0? 17 System upTime Menu Item Added You can display the length of time — in minutes, hours, and days — since the last system reboot. To display system upTime: 1 From the top level of the Administration Console, enter: system upTime System upTime is displayed. New FDDI MAC Statistic Added A new FDDI MAC statistic, rxErrors, has been added.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE New Fields Added to FDDI MAC Summary and Detail Five fields — currentPath, location, rxErrors, smtAddress, and station — have been added to the summary display for the FDDI MAC. The field rxErrors has been added to the detail display. Field descriptions, a sample FDDI MAC summary, and a sample FDDI MAC detail are shown here.
What’s New at Revision 8.0.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE Source Route Hop Count Limit Now Configurable You can now restrict token ring traffic by configuring the Source Route (SR) hop count limit. To configure the SR hop count limit, from the top level of the Administration Console, enter: srHopLImit You are prompted to enter the limit you want. You may set a limit from 1 through 7. The default is 7.
System Issues Software Changes and Corrections at 8.0.0 21 The following system issues and known problems have been corrected 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. ■ IP routing cannot be disabled unless IP RIP is not active and IP icmpRouterDiscover is disabled. ■ The LMM+ no longer hangs when assigning an RNM probe to an ESM port.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE ■ Roving Analysis frames over a remote Fast Ethernet connection are truncated if greater than 1495 bytes. ■ ESMs do not support IGMP snooping. IP multicast traffic should be filtered using a packet filter to avoid unwanted traffic. ■ EFSM packet filters can access packet data through byte 64 in the packet. ■ Bridging and routing performance are degraded on a Roving Analysis monitor port.
Known Problems 23 you do this, however, the system fails when you attempt to remove one of the interfaces. In the following example, the FDDI and the Ethernet interfaces both have class B IP addresses, and both have the same subnet mask: FDDI interface 158.101.101.1 Subnet mask: 255.255.0.0 Ethernet interface: 158.101.20.1 Subnet mask: 255.255.0.0 Do not assign different subnet masks to these interfaces (such as 255.255.255.0 and 255.255.0.0) if they have the same class of IP address.
LANPLEX® 6000 EXTENDED SWITCHING SOFTWARE SNMP MIB Files 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 for each of the supported compilers described at the end of this section. Supported Versions The SNMP MIB file names and the currently supported version of each MIB are listed here: ■ bridge.mib — Bridge MIB, RFC 1493 ■ ethernet.mib — Ethernet MIB, RFC 1398 ■ if.
SNMP MIB Files ■ 25 mib2schema (with SunNet Manager version 2.0) The MIB file fddiSmt7.mib produces the following warning messages when compiled using mib2schema: Translating....

IP MULTICAST ROUTING A 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 interfaces and routes as described in the LANplex® 6000 Extended Switching User Guide.
A-2 APPENDIX A: IP MULTICAST ROUTING Enabling and Disabling DVMRP DVMRP is the simple Distance Vector Multicast Routing Protocol, similar to the IP Routing Information Protocol. Multicast routers exchange distance vector updates that contain lists of destinations and the distance in hops to each destination. The routers maintain this information in a routing table. To run multicast routing, you must enable DVMRP, which enables it on all IP interfaces that have not been disabled.

Both are enabled by default.
A-4 APPENDIX A: IP MULTICAST ROUTING Rate Limit The rate limit determines how fast multicast traffic can travel over the interface 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. The default is set to 0, which implies no rate limit. In all other instances, the lower the rate limit, the more limited the traffic over the interface.

A-6 APPENDIX A: IP MULTICAST ROUTING Administering Multicast Tunnels 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 interface on the LANplex router. When you define the tunnel, you specify the associated index on the local LANplex router and then the characteristics of the tunnel. Tunnel characteristics are the same as those of an interface.
