Introduced on the S4820T. Introduced on the S4810. 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 configure the unit ID of a VLT peer. Configure a different 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. Virtual Link Trunking (VLT) 1866
