Traffic Mirroring

Displaying the Mirroring Configuration for a Specific SessionSyntax: show monitor < 1 - 4 name < name-str>

Use this command to display detailed configuration information for a specified local or remote mirroring session on a source switch.

Session: Displays the number of the specified session.Session Name: Displays the name of the session, if configured.

Policy: Indicates whether the source is using a classifier-based mirroring policy to select inbound IPv4 or IPv6 traffic for mirroring.

Mirroring Destination: For a local mirroring session, displays the port configured as the exit port on the source switch. For a remote mirroring session, displays IPv4, which indicates mirroring to a remote (endpoint) switch.

UDP Source Addr: The IP address configured for the source VLAN or subnet on which the monitored source interface exists. In the configuration of a remote session, the same UDP source address must be configured on the source and destination switches.

UDP port: The unique UDP port number that identifies a remote session. In the configuration of a remote session, the same UDP port number must be configured on the source and destination switches.

UDP Dest Addr: The IP address configured for the destination VLAN or subnet on which the remote exit port exists. In the configuration of a remote session, the same UDP destination address must be configured on the source and destination switches.

Status: For a remote session, displays current session activity:

active: The session is configured and is mirroring traffic. A remote path has been discovered to the destination.

inactive: The session is configured, but is not currently mirroring traffic. A remote path has not been discovered to the destination.

not defined: Mirroring is not configured for this session.

Monitoring Sources: For the specified local or remote session, displays the source (port, trunk, or VLAN) interface and the MAC address (if configured) used to select mirrored traffic.
