4. (Optional) 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.
VLT DOMAIN CONFIGURATION mode
unit-id {0 | 1}
To explicitly configure the default values on each peer switch, use the unit-id command.
Configure a different unit ID (0 or 1) on each peer switch.
Unit IDs are used for internal system operations.
Use this command to minimize the time required for the VLT system to determine the unit ID
assigned to each peer switch when one peer switch reboots.
Connecting a VLT Domain to an Attached Access Device (Switch or Server)
To connect a VLT domain to an attached access device, use the following commands.
On a VLT peer switch: To connect to an attached device, configure the same port channel ID number on
each peer switch in the VLT domain.
1. Configure the same port channel to be used to connect to an attached device and enter interface
configuration mode.
CONFIGURATION mode
interface port-channel id-number
2. Remove an IP address from the interface.
INTERFACE PORT-CHANNEL mode
no ip address
3. Place the interface in Layer 2 mode.
INTERFACE PORT-CHANNEL mode
switchport
4. Add one or more port interfaces to the port channel.
INTERFACE PORT-CHANNEL mode
channel-member interface
interface: specify one of the following interface types:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/
subport information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port
information.
5. Ensure that the port channel is active.
