Configuring Interop Mode 1
You can interop mode1 in Cisco SAN switches disruptively or nondisruptively.
Note
Brocade's msplmgmtdeactivate command must explicitly be run prior to connecting from a Brocade
switch to either Cisco SAN switches or to McData switches. This command uses Brocade proprietary
frames to exchange platform information, which Cisco SAN switches or McData switches do not recognize.
Rejecting these frames causes the common E ports to become isolated.
DETAILED STEPS
Command or Action
Step 1
Place the VSAN of the E ports that
connect to the OEM switch in
interoperability mode.
Step 2
Assign a domain ID in the range of 97
(0x61) through 127 (0x7F).
Step 3
Change the Fibre Channel timers (if they
have been changed from the system
defaults).
Step 4
When making changes to the domain, you
may or may not need to restart the Domain
Manager function for the altered VSAN.

switches.
In Cisco SAN switches, the default is to request an ID from the principal switch.
If the preferred option is used, Cisco SAN switches request a specific ID, but
still join the fabric if the principal switch assigns a different ID. If the static
option is used, the Cisco SAN switches do not join the fabric unless the principal
switch agrees and assigns the requested ID.
When changing the domain ID, the FC IDs assigned to N ports also

change.
Note
The Cisco SAN switches, Brocade, and McData FC Error Detect
(ED_TOV) and Resource Allocation (RA_TOV) timers default to the
same values. They can be changed if needed. The RA_TOV default
is 10 seconds, and the ED_TOV default is 2 seconds. Per the FC-SW2
standard, these values must be the same on each switch within the
fabric.
switch(config)# fctimer e_d_tov ?
<1000-100000> E_D_TOV in milliseconds(1000-100000)
switch(config)# fctimer r_a_tov ?
<5000-100000> R_A_TOV in milliseconds(5000-100000)
• Force a fabric reconfiguration with the disruptive option.
switch(config)# fcdomain restart disruptive vsan 1
or
• Do not force a fabric reconfiguration.
switch(config# fcdomain restart vsan 1
