Connectivity Repeat the following procedure until all domain ID conflicts are resolved. 1. Enter the fabricShow command on a switch from one of the fabrics. 2. In a separate Telnet window, enter the fabricShow command on a switch from the second fabric. 3. Compare the fabricShow output from the two fabrics. Note the number of domain ID conflicts; there may be several duplicate domain IDs that must be changed. Determine which switches have domain overlap and change the domain IDs for each of those switches. 4. Choose the fabric on which to change the duplicate domain ID; connect to the conflicting switch in that fabric. 5. Enter the switchDisable command. 6. Enter the configure command. 7. When the Fabric Parameters prompt displays, type y . 8. When the Domain prompt displays, type in the new number. 9. Press Enter on all prompts to accept their default settings. NOTE Do not press Ctrl+C as this might exit the configuration without saving it. 10. Enter the switchEnable command. This enables the joining switch to obtain a new domain ID as part of the process of coming online. The fabric principal switch allocates the next available domain ID to the new switch during this process. 11. Repeat step 4 through step 10 if additional switches have conflicting domain IDs.

4.
Choose the fabric on which to change the duplicate domain ID; connect to the conflicting switch in that fabric.
5.
Enter the
switchDisable
command.
6.
Enter the

7.
When the
Fabric Parameters
prompt displays, type
