vlt domain domain-id
The range of domain IDs is from 1 to 1000.
2 (Optional) After you congure the VLT domain on each peer switch on both sides of the interconnect trunk, by default, Dell
Networking OS elects a primary and secondary VLT peer device.
VLT DOMAIN CONFIGURATION mode
primary-priority value
To recongure the primary role of VLT peer switches, use the primary-priority command. To congure the primary role on a VLT
peer, enter a lower value than the priority value of the remote peer.
The priority values are from 1 to 65535. The default is 32768.
3 (Optional) When you create a VLT domain on a switch, Dell Networking OS automatically creates a VLT-system MAC address used for
internal system operations.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
To explicitly congure the default MAC address for the domain by entering a new MAC address, use the system-mac command. The
format is aaaa.bbbb.cccc.
Also, recongure the same MAC address on the VLT peer switch.
Use this command to minimize the time required for the VLT system to synchronize the default MAC address of the VLT domain on
both peer switches when one peer switch reboots.
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 congure the default values on each peer switch, use the unit-id command.
Congure a dierent 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, congure the same port channel ID number on each peer switch in the VLT
domain.
1 Congure the same port channel to use to connect to an attached device and enter Interface Conguration mode.
CONFIGURATION mode
interface port-channel id-number
2 Remove an IP address from the interface.
