About Port Snooping

Port-based snooping, or mirroring, lets you transparently mirror traffic from a source port(s) to a destination port. Multiple snooping sessions can operate simultaneously. You can specify whether the source ports are mirrored for transmit, receive, or both directions at once.

Port snooping augments the first four RMON groups (mini-RMON). For a description of RMON, see the “Remote Monitoring” section on page 1-11.

Port-based snooping features include the following:

•Traffic on one or more source ports through a destination port in the same switch router

•Traffic from multiple source ports in multiple directions: transmitting, receiving, or both

•Multiple snoop destination ports operating simultaneously (however, there is only one destination port per snooping session)
