Service Manual
To recongure the default MAC address for the domain by entering a new MAC address in the format
nn:nn:nn:nn:nn:nn, use the system-mac command.
You must also recongure the same MAC address on the VLT peer switch.
unit-id
Explicitly congure the default unit ID of a VLT peer switch.
Syntax
unit-id [0 | 1]
Parameters
0 | 1 Congure the default unit ID of a VLT peer switch. Enter 0 for the rst peer or
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, 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.
