Viewing the mirroring configuration for a specific session

Syntax


show monitor [1 - 4 | name name-str]

Displays 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.

Direction

For the selected interface, indicates whether mirrored traffic is entering the switch (in), leaving the switch (out), or both.
