Chapter 22: Performance Monitoring Guide

Configuring the SSR for Port Mirroring

The SSR allows you to monitor activity with port mirroring. Port mirroring allows you to monitor the performance and activities of ports on the SSR or for traffic defined by an ACL through just a single, separate port. While in Configure mode, you can configure your SSR for port mirroring with a simple command line like the following:

Configure Port Mirroring.

port mirroring monitor-port <port number> target- port <port list>target-profile <acl name>

Note: • Port mirroring is available for WAN ports. However, you cannot configure port mirroring on a port-by-port basis. (You can only configure port mirroring for the entire WAN card).

• Only IP ACLs can be specified for port mirroring.

Monitoring Broadcast Traffic

The SSR allows you to monitor broadcast traffic for one or more ports. You can specify that a port be shut down if its broadcast traffic reaches a certain rate limit for a particular period of time. You can also specify the duration of the port shut down. To specify the monitoring of broadcast traffic and the shut down threshold for one or more ports, enter the following command in Configure mode:

Configure monitoring of broadcast traffic.

port bmon <port list> rate <number> duration <number> shutdown <number>
