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.
vlt domain
Enable VLT on a switch, congure a VLT domain, and enter VLT-domain conguration mode.
Syntax
vlt domain domain-id
Parameters
domain-id Enter the Domain ID number. Congure the same domain ID on the peer switch.
The range of domain IDs is from 1 to 1000.
