Parameters
0 | 1 Configure the default unit ID of a VLT peer switch. Enter 0 for the first peer. Enter
1 for the second peer.
Defaults Automatically assigned based on the MAC address of each VLT peer. The peer with the lower MAC
address is assigned unit 0; the peer with the higher MAC address is assigned unit 1.

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.
