1. Determine the Mirroring Session Identity and
Destination
For a Local Mirroring Session. Determine the port number for the exit
port (such as A5, B10, etc.), then go to "4. Configure Mirroring Sources" on
page B-47.
For a Remote Mirroring Session. Determine the following and then go to
step 2, below.
■ the IP address of the VLAN or subnet on which the exit port exists on the
destination switch
the port number for the desired exit port on the destination switch (On
■
the destination switch, the mirrored traffic entry port for a given remote
mirroring session and the exit port for that session must belong to the
same VLAN.)
■ 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 (The recommended
■
range is 7933-65535. Refer to the following "Caution".)
Although the switch allows use of UDP port numbers in the range of 1 to 65535,
UDP port numbers below 7933 are reserved for various IP applications. Using
them for mirroring can result in disrupting other IP functions, and can also
result in non-mirrored traffic received on the destination switch being sent to
a mirroring exit port.)
2. Configure the Remote Mirroring Session on
Destination Switch
This step is needed when the exit port for a mirroring session is on a different
switch than the mirroring source. (For local mirroring, go to step 3 on page
B-47.) In this case, the mirroring destination switch must be configured to
recognize each unique mirroring session and assign its traffic to an exit port
before the source switch is configured to send mirrored traffic. This is done
by configuring the destination switch with the values determined for remote
mirroring in step 1, above.
A switch operating as a destination for mirrored traffic sessions can support
32 different remote sessions (and 4 local sessions). Multiple sessions can be
assigned to the same exit port or distributed to multiple exit ports.
