2.2.2 Management Module Ethernet

Figure 2-4illustrates the Management Module Ethernet interface. The switch modules are configured by the active Management Module through the use of a 100 Mb Ethernet interface. Each Management Module has four 100 Mb Ethernet interfaces, one for each switch module. Each switch module has two 100 Mb Ethernet interfaces, one for each Management Module.

Note: On the Nortel Networks L2/3 GbESM, the management Ethernet ports on the switch are referred to as MGT1 and MGT2. For more information beyond this generic illustration, see Chapter 4, “Nortel Networks Layer 2/3 GbE Switch Module architecture” on page 21.

The following list clarifies the routing:

￿Management Module 1 Ethernet 2 Switch Module 2 Ethernet MGT1

￿Management Module 1 Ethernet 3 Expansion Switch Module 3 Ethernet MGT1

￿Management Module 1 Ethernet 4 Expansion Switch Module 4 Ethernet MGT1

￿Management Module 2 Ethernet 1 Switch Module 1 Ethernet MGT2

￿Management Module 2 Ethernet 2 Switch Module 2 Ethernet MGT2
