Setting a Unit ID for a Switch
On the switches that support automatic numbering, FTM will automatically number the switches to
constitute an XRN fabric by default, so that each switch has a unique unit ID in the fabric. You can use
the command in the following table to set unit IDs for switches. Make sure to set different unit IDs for
different switches in an XRN fabric. Otherwise, FTM will automatically number the switches with the
same unit ID.
Follow these steps to set a unit ID for a switch:

By default, the unit ID of a
switch that belongs to no XRN
fabric is 1. The unit ID of a
switch belonging to an XRN
fabric is assigned by FTM. Unit
ID ranges from 1 to 8.
If you do not configure the fabric port, you cannot change the unit ID of the local switch.
After an XRN fabric is established, you can use the following command to change the unit IDs of the
switches in the XRN fabric.
