8683POSM module 57

To operate, each module requires at least one of the following MDAs:

•1-port OC-12c/STM-4: SMF or MMF using SONET media

•2-port OC-3c/STM-1: SMF or MMF using SONET media

The 8683POSM module supports a mixture of OC-3c/STM-1 and OC-12c/STM-4 lines. For example, you can install an OC-12c/STM-4 MDA in the first bay and OC-3c/STM-1 MDAs in the two remaining bays. This module supports up to six I/O OC-3c/STM-1 lines and up to three I/O OC-12c/STM-4 lines.

The 8683POSM module has an online LED that indicates overall status for the module. "8683POSM module LED" (page 57) describes the online LED.

See Using the 8683POSM Module (209564-C) for a description of how to configure the 8683POSM module using the command line interface (CLI) or Device Manager.

The 8683POSM 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 ARP entries

This mode supports R modules only.
