enable

Syntax

enable

Description

Enables the mirroring session for the current command context.

Command context

config-mirror-<SESSION-ID>

Authority

Administrators or local user group members with execution rights for this command.

Usage

By default, mirroring sessions are disabled.

When a mirroring session is enabled, the show mirror command for that session ID shows an Admin Status of enable and an Operation Status of enabled.

If sFlow is enabled on an interface and a mirroring session specifies the same interface as the source of received traffic (the source is configured with a direction of rx or both):

  • The attempt to enable the mirroring session fails and an error is returned.

  • To enable the mirroring session, first you must disable sFlow on the port.

NOTE:

When adding, removing, or changing the configuration of a source interface in an enabled mirroring session, packets from other mirror sources using the same destination interface might be interrupted.

Example

Configuring and enabling a mirroring session:

switch(config)# mirror session 3
switch(config-mirror-3)# source interface 1/1/2 rx
switch(config-mirror-3)# destination interface 1/1/3
switch(config-mirror-3)# comment Monitor router port ingress-only traffic
switch(config-mirror-3)# enable
