Monitoring and Analyzing Switch Operation
Traffic Mirroring
Syntax: [no] mirror < 1 - 4 > [name < name-str >] remote ip < src-ip >
< src-udp-port > < dst-ip >
This command is used on the source switch to uniquely
associate the mirrored traffic from a specific mirroring
session with a specific, remote exit switch. Thus, for a given
mirroring session, the same source and destination values
should be configured on both the mirroring destination
switch and the mirroring source switch.(Each remote
mirroring session having the same source and destination
IP addresses should have a unique UDP port value.)
Whey you execute this command, this message appears:
Caution: Please configure destination switch first.
Do you want to continue [y/n]?
• If you have not yet configured the session on the
mirroring destination switch, use the instructions in
step 2 on page B-41 to do so before using this command.
• If you previously configured the session on the mirroring
destination switch, type y (for “yes”) to complete this
command.
The no form of the command removes the mirroring session
and any mirroring source previously assigned to that
session. To preserve the session while deleting a mirroring
source assigned to it, refer to the no command descriptions
under “4. Configure Mirroring Sources” on page B-47.
< 1 - 4 > : Identifies the mirroring session created by this
command.
name < name-str >: Optional alphanumeric name string used
as an additional session identifier. Can be up to 15
characters in length.
< src-ip > : The IP address of the VLAN or subnet on which
the traffic to be mirrored enters or leaves the switch.
