The 8608GBE module supports up to 32 000 table entries in its forwarding
engine. For information about table entry characteristics, see Network
Design Guidelines (313197-E).
The 8608GBM module is an M module and supports up to 128 000 table
entries in its forwarding engine, allowing for large Layer 2 and Layer 3
configurations, including Internet routing tables. For information about table
entry characteristics, see Network Design Guidelines (313197-E).
The Metro Ethernet Routing Switch 8600 system has three hardware
operating modes:

Meaning
The module has completed its power-on
self-test and software initialization and
is operating normally.
The module failed its power-on self-test.
The switch power is off. If the switch
power is on, the module is going through
its power-on self-test and software
initialization. A module in this state is
not yet functional.
