Parameter
unit-id1: Current unit ID.
unit-id2: New unit ID.
auto-numbering: Change the unit ID automatically.
Description
Use the change unit-id command to configure the unit ID of a switch in an IRF fabric to
a new value. By default, when a switch is added to an IRF fabric, it uses the
automatically assigned unit ID.
If the modified unit ID does not exist in the fabric, the system sets its priority to 5
and saves it in the unit Flash memory.
If the modified unit ID is an existing one, the system prompt you to confirm if you
really want to change the unit ID. If you choose to change, the existing unit ID is
replaced and the priority is set to 5. Then you can use the fabric save-unit-id
command to save the modified unit ID into the unit Flash memory and clear the
information about the existing one.
If auto-numbering is selected, the system sets the unit ID priority to 10. You can
use the fabric save-unit-id command to save the modified unit ID into the unit
Flash memory and clear the information about the existing one.
Note:
Unit IDs in the fabric are not always arranged in order of 1 to 8.
Unit IDs in an IRF fabric can be inconsecutive.
For the related command, see fabric save-unit-id.
Example
# Change the unit ID of the switch from 6 to 4. Use the display ftm command to display
information about each unit in the fabric.
