Usage Information
When you create a VLT domain on a switch, Dell Networking OS automatically assigns a unique unit ID (0 or 1) to
each peer switch. The unit IDs are used for internal system operations. Use the unit-id command to explicitly
congure the unit ID of a VLT peer. Congure a dierent unit ID (0 or 1) on each peer switch.
To minimize the time required for the VLT system to determine the unit ID assigned to each peer switch when one
peer reboots, use this command.

Syntax
vlt domain domain-id
Parameters

range of domain IDs is from 1 to 1000.
