1. Verify that you have implemented all the Brocade prerequisites necessary to enable 

interopMode 3 on the fabric (see 

2. Connect to the switch and log in using an account assigned to the admin role.

3. Enter the switchDisable command.

switch:admin> switchdisable

4. Enter the configure command to set the domain ID to a number in the range from 97 to 127; 

otherwise, the interopMode command defaults to 97. (For detailed instructions, see 

.)

switch:admin> configure
Configure...
Fabric Parameters (yes, y, no, n): [no] y 
Domain (1...239): [1] 97

5. Enter the interopMode 3 command to enable interoperability. This command resets a number 

of parameters and enables McDATA Open Fabric mode.

switch:admin> interopmode 3
The switch effective and defined configuration
will be lost if interop Mode is changed.

Interop Mode or Domain Offset Will Be Changed
and switch will be Enabled

Do you want to continue? (yes, y, no, n): [no] y

6. Repeat 

 through 

 on each Fabric OS switch in the fabric. 

7. After enabling McDATA Open Fabric mode on all switches, physically connect the legacy M-EOS 

switches to the Fabric OS fabric, one at a time.

Enabling McDATA Fabric mode

When McDATA Fabric mode is enabled, the OUI portion of the switch WWN is no longer replaced 
with a McDATA OUI. All existing zoning configurations are cleared. 

1. Verify that you have implemented all the Brocade prerequisites necessary to enable 

interopMode 2 on the fabric (see 

page 301.)

2. Connect to the switch and log in using an account assigned to the admin role.

3. Enter the switchDisable command.

switch:admin> switchdisable

4. Enter the configure command to set the domain ID to a number in the range from 1-31. (For 

detailed instructions, see 

.)

switch:admin> configure
Configure...
Fabric Parameters (yes, y, no, n): [no] y 
Domain (1...31): [1] 5

5. Enter the interopMode 2 command to enable interoperability. This command resets a number 

of parameters and enables fabric mode.
