Non-Unique VSAN IDs Using AFIDs
As of Cisco MDS SAN-OS Release 2.1(1a), you can configure more than one AFID. This feature allows
more than one VSAN in the network with the same VSAN ID. Using this feature you can avoid downtime
when enabling IVR between fabrics that contain VSANs with the same ID. However, for VSANs with
the same ID to communicate, there must be a transit VSAN with a different VSAN ID between the source
and target VSANs.
Note
AFID configuration is used only when the VSAN topology mode is automatic. In user-configured VSAN
topology mode, the AFIDs are specified in the VSAN topology configuration itself and a separate AFID
configuration is not needed.
Configuring the AFID Database
To configure the AFID database, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# autonomous-fabric-id database
Step 3
switch(config-afid-db)# switch-wwn
20:00:00:0c:91:90:3e:80 autonomous-fabric-id
10 vsan-ranges 1,2,5-8
switch(config-afid-db)# no switch-wwn
20:00:00:0c:91:90:3e:80 autonomous-fabric-id
2 vsan-ranges 3
