Virtual Link Trunking (VLT) | 965
(Optional) Reconfigure default VLT settings
Step Task Command Syntax Command Mode
1 Enter VLT-domain configuration mode for a specified
VLT domain.
Range of domain IDs: 1 to 1000.
vlt domain domain-id CONFIGURATION
2 (Optional) After you configure the VLT domain on each
peer switch on both sides of the interconnect trunk, by
default, the Dell networking OS software elects a
primary and secondary VLT peer device.
Use the primary-priority command to reconfigure the
primary role of VLT peer switches. To configure the
primary role on a VLT peer, enter a lower value than the
priority value of the remote peer.
Priority values are from 1 to 65535. Default: 32768.

CONFIGURATION
3 (Optional) When you create a VLT domain on a switch,
the Dell networking OS software automatically creates a
VLT-system MAC address used for internal system
operations.
Use the system-mac command to explicitly configure
the default MAC address for the domain by entering a
new MAC address in the format: aaaa.bbbb.cccc.
You must also reconfigure 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.

CONFIGURATION
4 (Optional) When you create a VLT domain on a switch,
the Dell networking OS software 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
default values on each peer switch.
You must configure a different unit ID (0 or 1) on each
peer switch.
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.
