Off 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.
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:
• Default mode (32 000 table entries) supports up to 32 000 hardware
records. This mode supports all modules.
•
M mode (128 000 table entries) supports up to 128 000 hardware
records. This mode supports M modules only.
•
R mode supports up to:
— 256 000 IP routes
— 64 000 MAC entries
— 32 000 Address Resolution Protocol (ARP) entries
This mode supports R modules only.
The 8608GBE module does not support R or M mode. The 8608GBM
module supports R and M mode. For specific R and M mode configuration
requirements, see "R mode configuration requirements" (page 24) and "M
mode configuration requirements" (page 23).
8608GTE and 8608GTM modules
Both the 8608GTE and 8608GTM module ("8608GTE/8608GTM module"
(page 28)) provide eight 1000BaseT, copper Gigabit Ethernet ports with
8-pin modular (RJ-45) connectors. Each port operates in 1000 Mb/s
(1 Gb/s) full-duplex mode and supports IEEE 802.3 1998 Clause 28
