Performance Monitoring Overview
The SSR is a full wire-speed layer-2, 3 and 4 switching router. As packets enter the SSR,
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 SSR 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 SmartSwitch Router Command Line Interface Reference Manual.
