Traffic Mirroring
Displaying the Mirroring Configuration for a Specific Session
Syntax: 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.
