12 Fabric Interoperability: Merging Fabrics Based on C-Series and M-Series Fibre Channel Switches Application Notes
MDS9509# config t
MDS9509(config)# vsan database
MDS9509(config-vsan-db)# vsan 1 suspend
MDS9509(config)# fctimer e_d_tov 2000
<1000-100000> E_D_TOV in milliseconds(1000-100000)
MDS9509(config)# fctimer r_a_tov 10000
<5000-100000> R_A_TOV in milliseconds(5000-100000)
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 M-series in interoperability mode.
MDS9509# config t
MDS9509(config)# vsan database
MDS9509(config-vsan-db)# vsan 1 interop 1
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 can force a fabric reconfiguration with the following commands.
MDS9509(config)# vsan database
MDS9509(config-vsan-db)# vsan 1 suspend
MDS9509(config-vsan-db)# no vsan 1 suspend
MDS9509(config-vsan-db)# exit
MDS9509(config)# exit
