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 different exit ports
■ You can segregate traffic by type, direction, or source.
A given switch can operate as both a source and a destination for mirroring
sessions.
Configuration
Table B-1 lists the traffic mirroring configuration support available through
the CLI, Menu Interface, and SNMP methods.

N o t e
Using the CLI, you can access all mirroring capabilities on the switch. Using
the Menu or Web interfaces, you can configure and display only session 1 and
only as a local mirroring session for traffic in both directions on the specified
interface. If session 1 has been configured in the CLI for local mirroring for
inbound-only or outbound-only traffic, then using the Menu or Web interface
to change the session 1 configuration
automatically reconfigures the session
to monitor both inbound and outbound traffic on the interface. (If session 1
has been configured in the CLI with an ACL or as a remote mirroring session,
then the Menu and Web interfaces cannot be used to configure a mirroring
session.) The CLI can configure sessions 1 - 4 for local or remote mirroring in
any combination, and can be used to override a Menu or Web interface
