Figure 148: MSM-3 Module
The MSM-3 module allows cross-module trunking on the BlackDiamond 6804 and 6808 chassis.
Cross-module trunking is the ability for a load-share group to span multiple modules. Load-sharing
groups are still limited to a maximum of eight ports, but the ports can be located on any number of
different modules. For more information about cross-module trunking, see the
ExtremeWare Software
User Guide .
The MSM consists of a printed circuit board mounted on a metal panel that acts as the insertion vehicle
in a BlackDiamond 6800 series switch. The module carrier also includes ejector/injector levers and
captive retaining screws at each end of the module front panel.
Each MSM has the following ports:
• Console port—Used to connect a terminal and perform local management.
• Management port—Used to connect an Ethernet cable directly from your laptop into the
management port to view and locally manage the switch configurations.
• Modem port—Used to connect a modem for remote access to the CLI.
• PCMCIA slot—Reserved for future use.
See Chapter 1, “Common Switch Features” for more information about management ports. For
information about BlackDiamond MSM module specifications, see Appendix C, “Module Technical
Specifications.”
MSM Activity
The BlackDiamond 6800 series switch can run with a single MSM installed. When you install additional
MSMs, one of the MSMs operates as the
master , and the others become the slaves .
The master MSM is responsible for upper-layer protocol processing and system management functions.
For example, OSPF computation and SNMP functions are performed by the master MSM. Packet
handling is distributed among the CPUs of all installed MSMs.
