Configuring a source switch in a local mirroring session
Enter the

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.
