642 Port Monitor Commands
monitor session
Use the monitor session command in Global Configuration mode to
configure a probe port and a monitored port for monitor session (port
monitoring). Use the src-interface 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 | tx} option, the destination port
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.
