Usage
Information
When you create a VLT domain on a switch, FTOS 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.
vlt domain
Enable VLT on a switch, configure a VLT domain, and enter VLT-domain configuration mode.

Syntax

Parameters

1000.
