Introduction
14 Fabric Interoperability: Merging Fabrics Based on C-Series and M-Series Fibre Channel Switches Application Notes
Configure Zones using only Port Level Device WWNs
In the interoperability mode all the zone members must be defined using port level device
WNNs only and defining them in any other way is not supported. For example, we can not
define zones using FC port addresses or domain, port combinations etc. If there are any zones
not defined as stated above, redefine them using proper port level device WWNs.
Step C6: Configure FCIDs with unique AREA bytes
It is required to configure each FCID with a unique AREA byte on MDS switches for the
M-series and C-series switches to work properly in the interoperating fabric. Follow these
steps to achieve this:
■ enable persistent FCID
■ configure unique AREA byte
Enable persistent FCID
MDS9509# config t
MDS9509(config)# fcdomain fcid persistent vsan 1
MDS9509(config)# exit
MDS9509#
Configure unique AREA byte
Now, verify if there are any devices with the same domain and AREA byte on the MDS
switches. If there are such duplicates, then change these FCIDs manually to configure unique
AREA byte.
As an example, consider two ports with the same AREA byte:
fc1/1(0x010501, wwn xx:xx:xx:xx:xx:xx:xx:xx) and
fc1/2(0x 010502, wwn yy:yy :yy:yy :yy:yy :yy:yy)
■ Obtain the WWN of the port to be configured. The "show flogi database" command can be
used for this purpose.
■ Shut down the ports to be configured
MDS9509# config t
MDS9509(config)# interface fc1/1
MDS9509(config)# shutdown
MDS9509(config)# interface fc1/2
MDS9509(config)# shutdown
MDS9509(config)# end
MDS9509#
■ Now change the AREA byte
MDS9509# config t
MDS9509(config)# fcdomain fcid database
MDS9509(config-fcid-db))# vsan 1 wwn xx:xx:xx:xx:xx:xx:xx:xx fcid
0x01dd00
MDS9509(config-fcid-db))# vsan 1 wwn yy:yy:yy:yy:yy:yy:yy:yy fcid
0x01ee00
MDS9509(config)# end
MDS9509#
