FC and RSPAN Tunnel
Guidelines to Configure RSPAN
The following guidelines apply for a SPAN configuration:
•
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 will be dropped.
•
The FC tunnel IP address must reside in the same subnet as the VSAN interface.
•
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 (the
trunk protocol enable
command is enabled by default).
–
VSAN interface must be configured (the
interface vsan
command).
–
The Fibre Channel tunnel feature must be enabled (the
fc-tunnel enable
command is disabled
by default).
–
IP routing must be enabled (the
ip routing
command is disabled by default).
•
If the IP address is in the same subnet as the VSAN, the VSAN interface does not have to 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.
ST Port Characteristics
ST port have the following characteristics:
•
ST ports perform the RSPAN encapsulation of the FC frame.
•
ST ports do not use BB_credits.
•
An ST port can only be bound to one FC tunnel.
•
ST ports cannot be used for any other purpose other than to carry RSPAN traffic.
