Monitoring and Analyzing Switch Operation
Traffic Mirroring
as described in “2. Configure a Mirroring Destination on a Remote Switch” on
page B-50, before using the mirror remote ip command in this section to
configure the mirroring source for the same session.
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 in the specified session with
a remote destination switch. You must configure the same
source and destination parameters when you configure the
same session on both the source and destination switches.
(If multiple remote sessions use the same source and
destination IP addresses, each session must use a unique
UDP port value.)
When you execute this command, the following message is
displayed:
Caution: Please configure destination switch first.
Do you want to continue [y/n]?
• If you have not yet configured the session on the remote
destination switch, follow the configuration procedure in
Step 2 on page B-50 before using this command.
• If you have already configured the session on the remote
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 the
session. To preserve the session while deleting a monitored
source assigned to it, refer to the no command descriptions
in “4. Configure the Monitored Traffic in a Mirror Session”
on page B-55.
< 1 - 4 >: Identifies the mirroring session created by this
command.
name < name-str >: Optional alphanumeric name string used
as an additional session identifier (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.
