Chapter 20: 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 one or more 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:
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:
