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 can be accessed by SNMP through MIB-II and by the
command line through the l2-tables command. Layer-3 and 4 performance statistics
can be accessed by SNMP through RMON/RMON2 and through the CLI through the
statistics show command. In addition to the monitoring commands listed, you can find
more monitoring commands listed in each chapter of the SSR User Reference Manual.
