12 COREBUILDER 6000 INTELLIGENT SWITCHING SOFTWARE REVISION 8.2.0
To verify that you have an LMM+ module and not an LMM module
installed:
1 Check that the module’s ejector tab is labeled “LMM+”
2 Determine the revision of your LMM+. From the top level of the
Administration Console, enter:
system display
To upgrade your LMM or LMM+, see “Upgrading Your LMM or LMM+” on
page 4.
HSI Switch Engine
You can combine the Fast Ethernet Switching Module (FESM) and FDDI
Switching Module (FSM) into a multiboard high-speed interconnect (HSI)
switch engine. An HSI switch engine is a combined set of FSMs or FESMs
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 bridge the combined set of external ports on all modules in
that switch engine. Additionally, as you add a new module to an existing
HSI switch engine, the system automatically adds configuration
information for the existing HSI switch engine to the new module. You
must manually configure any port-specific information, however.
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 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.
If you change this operating mode to
full-duplex, the port transmits and receives data through two
separate channels.
