(Optional) Reconfigure default VLT settings Step Task Command Syntax 1 Enter VLT-domain configuration mode for a specified vlt domain domain-id VLT domain. Range of domain IDs: 1 to 1000. 2 (Optional) After you configure the VLT domain on each primary-priority value peer switch on both sides of the interconnect trunk, by default, the FTOS 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. 3 (Optional) When you create a VLT domain on a switch, system-mac mac-address the FTOS software automatically creates a VLT-system mac-address 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. 4 (Optional) When you create a VLT domain on a switch, unit-id {0 | 1} the FTOS 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.
