Setting unique Domain IDs
In a cascaded configuration, each switch must have a unique Domain ID, and insistent Domain ID (IDID)
mode must be enabled.
To set a unique Domain ID and enable IDID mode:
1. Connect to the switch and log in as admin.
2. Verify that the switch has a unique Domain ID. If it does not, set a unique Domain ID.
For instructions on displaying and changing the Domain ID, see ”Working with Domain IDs” on
page 33.
3. Issue the switchDisable command to disable the switch.
4. Issue the configure command.
5. Enter y after the Fabric Parameters prompt.
6. To enable IDID mode, enter y after the Insistent Domain ID Mode prompt.
You can disable this mode by entering n.
7. Respond to the remaining prompts (or press Ctrl-d to accept the other settings and exit).
8. Issue the switchEnable command to re-enable the switch:
