What’s New at Revision 8.2.0? 15
To verify that you have an LMM+ module and not an LMM module installed:
1 Verify that the module’s ejector tab is labeled “LMM+”.
2 Determine the revision level of your LMM+. From the top level of the
Administration Console, enter:

FESM and FSM HSI Switch Engine
You can combine the Fast Ethernet Switching Module (FESM) and the FDDI
Switching Module (FSM) into a multiboard high-speed interconnect (HSI)
switch engine.
An HSI switch engine is a combined set of FSMs, FESMs, or both, which,
when inserted into the HSI bus according to specific configuration rules,
operates as a single switch. Multiple FSMs and FESMs in a single HSI switch
engine form a bridge out of the combined set of external ports on all
modules in that switch engine. As a new module is added to an existing HSI
switch engine, configuration information for the existing HSI switch engine
is added to the new module. You must manually configure any port-specific
information.
Ability to Administer Fast Ethernet Ports
New menus on the Administer menu allow you to administer Fast Ethernet
ports on the Fast Ethernet Switching Module (FESM) and the Tri-Media Fast
Ethernet Module (TMM-FE). You can now configure Fast Ethernet ports to
support:
■ Full-duplex operation
■ Intelligent flow management (IFM)
Full-duplex operation. By default, FESM and TMM Fast Ethernet ports
operate in half-duplex mode. In this mode, data flows through the port in
only one direction at a time.
When you change this operating mode to
full-duplex, the port transmits and receives data at the same time
through two separate channels.
