Enabling McDATA Open Fabric mode When configuring McDATA Open Fabric mode, avoid domain ID conflicts before fabric reconfiguration. When configuring multiple switches, you should wait for a fabric reconfiguration after adding or removing each switch. Every switch in the fabric must have a unique domain ID. To enable McDATA Open Fabric mode: 1. Verify that you have implemented all the Brocade prerequisites necessary to enable interopmode 3 on the fabric (see "McDATA Open Fabric mode configuration restrictions" on page 485.) 2. Connect to the switch and log in as admin. Ensure that the switch is disabled or offline. 3. Enter the switchDisable command to disable the switch. 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 will default you to 97. For detailed instructions, see "Working with domain IDs" on page 16. switch:admin> configure Configure... Fabric Parameters (yes, y, no, n): [no] y Domain (1...127): [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 McDATA Open Fabric mode is enabled The switch effective configuration will be lost. The system will reboot to allow the change to take effect. Do you want to continue? (yes, y, no, n): [no]y The configuration is being saved - a system reboot will cause the change to take effect. Please disable switch before changing the interop mode. The switch automatically reboots after changing the interoperability mode. 6.
