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-tablescommand 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 User Reference Manual.

To access statistics on the SSR, enter the following commands in Enable mode:

Show DVMRP routes.

dvmrp show routes

 

 

Show HTTP statistics.

http show statistics

 

 

Show all TCP/UDP connections

ip show connections

and services.
