CONFIGURATION mode vlt domain domain-id The range of domain IDs is from 1 to 1000. 2. (Optional) When you create a VLT domain on a switch, the system automatically creates a VLT- system MAC address used for internal system operations. VLT DOMAIN CONFIGURATION mode system-mac mac-address mac-address To explicitly configure 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, 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. 3. (Optional) When you create a VLT domain on a switch, the system 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 Virtual Link Trunking (VLT) 1083
