Usage
Information
When you create a VLT domain on a switch, Dell Networking OS automatically creates a VLT-system
MAC address used for internal system operations.
To reconfigure 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 reconfigure the same MAC address on the VLT peer switch.
unit-id
Explicitly configure the default unit ID of a VLT peer switch.
C9000 Series
Syntax
unit-id [0 | 1]
Parameters
0 | 1 Configure the default unit ID of a VLT peer switch. Enter 0 for the first 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.
