Usage Information
When you create a VLT domain on a switch, the Dell EMC Networking OS automatically assigns a unique unit ID
(0 or 1) to each peer switch. The unit IDs are used for internal system operations. To explicitly configure the unit
ID of a VLT peer, use the unit-id command. Configure a different unit ID (0 or 1) on each peer switch.
This command minimizes the time required for the VLT system to determine the unit ID assigned to each peer
switch when one peer reboots.
vlt domain
Enable VLT on a switch, configure a VLT domain, and enter VLT-Domain Configuration mode.
Syntax
vlt domain domain-id
Parameters
domain-id Enter the domain ID number. Configure the same domain ID on the peer switch. The
range of domain IDs is from 1 to 1000.
