Step C3: verify the fabrics are in proper operating mode
To enable interoperability mode on C-series switches, the first step is to place the VSAN of the
E_Ports(s) that connect to the B-series in interoperability mode.

MDS9509(config)# vsan database
MDS9509(config-vsan-db)# vsan 1 interop
Step C4: verify/configure switch domain IDs
The next step is to assign a domain ID in the range of 97 (0x61) through 127 (0x7F), while in
interoperability mode, we are limited to a total of 31 switches in the fabric. In the MDS the
default is to request an ID from the principal switch. If the preferred keyword is used, the
MDS will request a specific ID, but still join the fabric if the principal switch assigns a
different ID. If the static keyword is used, the MDS will not join the fabric unless the
principal switch agrees, and assigns the requested ID.
MDS9509# config t
MDS9509(config)# fcdomain domain 100 preferred vsan 1
When making changes to the domain, you may restart the MDS domain manager function for
the altered VSAN. You may force a fabric reconfiguration with the disruptive keyword.
MDS9509(config)# fcdomain restart disruptive vsan 1
Or not force a fabric reconfiguration
MDS9509(config)# fcdomain restart vsan 1
Step C5: verify proper zoning configuration is in place
Check for Duplicate Zone Sets (zones): To ensure proper zoning merge and operation, verify
there are no duplicate active ZoneSets or Zones across the two fabrics that need to be merged.
If any duplicate zones exist then rename them. You can verify zoning information by using the
“show zone” command.
For example, to verify all active zones …
