56 Metro Ethernet Routing Switch 8600 modules
See Using Metro Ethernet Routing Switch 8600 10 Gigabit Ethernet
Modules (315893-E) for a description of how to configure the 8681XLW
module using the command line interface (CLI) or Device Manager.
The 8681XLW module 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 ARP entries
This mode supports R modules only.
The 8681XLW 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) .
8683POSM module
The 8683POSM module ( "8683POSM module with an OC-12c/STM-4 MDA"
(page 56) ) has three bays for installing POS media dependent adapters
(MDAs). These MDAs provide MAN/WAN support by allowing access
to SONET services in the metropolitan area. You can connect multiple
campuses in a single metropolitan area without compromising performance
or increasing complexity. You can install up to four 8683POSM modules in
one 8010 10-slot chassis (four in a 8006 6-slot chassis, and two in a 8003
3-slot chassis).
