Monitoring and Analyzing Switch Operation
Traffic Mirroring
■ The IP address of the VLAN or subnet on which the mirrored traffic enters
or leaves the source switch
■ The unique UDP port number to use for the session on the source switch
(The recommended port range is from 7933 to 65535.)
Caution Although the switch supports the use of UDP port numbers from 1 to 65535,
UDP port numbers below 7933 are reserved for various IP applications. Using
these port numbers for mirroring can result in an interruption of other IP
functions, and in non-mirrored traffic being received on the destination (end-
point) switch and sent to the device connected to the remote exit port.
2. Configure a Mirroring Destination on a Remote
Switch
This step is required only if you are configuring a remote mirroring session in
which the exit port is on a different switch than the monitored (source)
interface. If you are configuring local mirroring, go to step 3 on page B-55.
For remote mirroring, you must configure the destination switch to recognize
each mirroring session and forward mirrored traffic to an exit port before you
configure the source switch. Configure the destination switch with the values
you determined for remote mirroring in “1. Determine the Mirroring Session
and Destination” on page B-49.
Note A remote destination switch can support up to 32 remote mirroring endpoints
(exit ports connected to a destination device in a remote mirroring session).
Configuring a Destination Switch in a Remote Mirroring Session.
Enter the mirror endpoint ip command on the remote switch to configure the
switch as a remote endpoint for a mirroring session with a different source
switch.
