Monitoring and Analyzing Switch Operation
Traffic Mirroring
■ You can reduce the risk of oversubscribing a single exit port by:
• Directing traffic from different session sources to multiple exit ports
• Configuring an exit port with a higher bandwidth than the monitored
source port
■ You can segregate traffic by type, direction, or source.
Mirroring Configuration
Table B-1 shows the different types of mirroring that you can configure using
the CLI, Menu, and SNMP interfaces.

In release K.14.01 and greater, the use of ACLs to select inbound traffic in a mirroring session
(using the <interface | vlan> monitor ip access-group in mirror command) has been deprecated
and is replaced with classifier-based mirroring policies.
