Performance Monitoring Overview

The XP is a full wire-speed layer-2, 3 and 4 switching router. As packets enter the XP,

layer-2, 3, and 4 flow tables are populated on each line card. The flow tables contain

information on performance statistics and traffic forwarding. Thus the XP provides the

capability to monitor performance at Layer 2, 3, and 4. Layer-2 performance information

is accessible to SNMP through MIB-II and can be displayed by using the l2-tables

command in the CLI. Layer-3 and 4 performance statistics are accessible to SNMP through

RMON/RMON2 and can be displayed by using the statistics show command in the CLI.

In addition to the monitoring commands listed, you can find more monitoring commands

listed in each chapter of the Enterasys Xpedition Command Line Interface Reference Manual.
