Management and Configuration Guide K/KA/KB.15.15

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.
Mirroring
Destination
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 Source Addr
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 port
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.
UDP Dest Addr
For a remote session, displays current session activity:Status
• 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.
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.
Monitoring Sources
For the selected interface, indicates whether mirrored traffic is entering the
switch (in), leaving the switch (out), or both.
Direction
Viewing a remote mirroring session
After you configure session 2 for remote mirroring (Figure 164 (page 334)), you can enter the show
monitor 2 command to verify the configuration (Figure 165 (page 334).)

Viewing a MAC-based mirroring session
After you configure a MAC-based mirroring session (Figure 166 (page 335)), you can enter the
show monitor 3 command to verify the configuration (Figure 167 (page 335).)
