switch.
Configuring the ST Port
Once the FC tunnel is created, be sure to configure the ST port to bind it to the FC tunnel at the source
switch. The FC tunnel becomes an RSPAN tunnel once the binding and mapping is complete.

Purpose
Enters configuration mode.
Initiates the FC tunnel (100) in the source switch
(switch S). The tunnel IDs range from 1 to 255.
Maps the IPv4 address of the source switch (switch
S) to the FC tunnel (100).
Maps the IPv4 address of the destination switch
(switch D) to the FC tunnel (100).
Enables traffic flow through this interface.
