Syntax Description

`mirror_name`	Displays the mirror name.
`mirror_name_li`	Displays mirror instance name for Lawful Intercept account only. You must have lawful intercept user privileges to specify this variable.
all	Displays all mirror instances.
enabled	Displays only enabled mirror instances.

N/A.

Usage Guidelines

Use this command to display mirror statistics and determine if mirroring is enabled or disabled on the switch.

For mirror instances to remote IP addresses, one the following statuses appears:

Disabled—User has disabled the mirror instance.
Down. No route—No route is available to reach the remote IP address.
Down. IP forwarding not enabled on VLAN to route—Route is available to reach the remote IP address, but egress VLAN does not have IP forwarding enabled (see enable ipforwarding).
Down. Ping timed out—Route is available, IP address forwarding is enabled on the egress VLAN, but ping check is “on” and a timely ping response from the remote IP address was not received during three consecutive ping requests, sent every five seconds.
Up—Remote IP address is reachable and ARP entry is resolved. Ping health check is either “off”, or is “on” and a timely ping response was received.

Note

The mirror instance for a remote IP address is only installed in hardware if the status is “Up”.
