FC and RSPAN Tunnel

ST port
All switches in the end-to-end path of the RSPAN tunnel must belong to the Cisco MDS 9000
Family.
All VSANs with RSPAN traffic must be enabled. If a VSAN containing RSPAN traffic is not
enabled, it is dropped.
The following configurations must be performed on each switch in the end-to-end path of the Fibre
Channel tunnel in which RSPAN is to be implemented:
Trunking must be enabled (enabled by default).
–
VSAN interface must be configured.
–
The Fibre Channel tunnel feature must be enabled (disabled by default).
–
– IP routing must be enabled (disabled by default).
If the IP address is in the same subnet as the VSAN, the VSAN interface does not have to
Note
be configured for all VSANs on which the traffic is spanned.
A single Fibre Channel switch port must be dedicated for the ST port functionality.
Do not configure the port to be monitored as the ST port.
The FC tunnel's IP address must reside in the same subnet as the VSAN interface
See Chapter 43, "Configuring IP Services."
ST ports perform the RSPAN encapsulation of the FC frame.
ST ports do not use BB_credits.
One ST port can only be bound to one FC tunnel.
