monitor session
Use the monitor session command in Global Configuration mode to
configure the source and destinaqtion for mirroring. Packets are copied from
the source to the destination. Use the source interace parameter to specify
the interface to monitor. Use rx to monitor only ingress packets, or use tx to
monitor only egress packets. If you do not specify an rx or tx option, the
session monitors both ingress and egress packets. Use the destination
interface to specify the interface to receive the monitored traffic. Use the
mode parameter to enabled the administrative mode of the session. If
enabled, the probe port monitors all the traffic received and transmitted on
the physical monitored port.
Use the no form of the command to remove the monitoring session.
