Configuring the XP for Port Mirroring

The XP allows you to monitor activity with port mirroring. Port mirroring allows you to

monitor the performance and activities of ports on the XP or for traffic defined by an ACL

through just a single, separate port. While in Configure mode, you can configure your XP

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 XP allows you to monitor broadcast traffic for one or more ports, and for the control

module. You can specify that a port be shut down if its broadcast traffic reaches a certain

rate limit for a particular period of time. Additionally, you can configure the XP to shut

down for a specified period, if the packets sent to the control module reach a certain limit

during a specified time interval. Packets to be monitored can be limited to broadcast

packets only or all packets.

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 Port

Mirroring.

port mirroring monitor-port <port number> target-port <port

list>

|target-profile <acl name>

Configure monitoring of

broadcast traffic.

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