The range is from 1 to 4094. Configuring Enhanced VLT (eVLT) (Optional) To configure enhanced VLT (eVLT) between two VLT domains on your network, use the following procedure. For a sample configuration, refer to eVLT Configuration Example. To set up the VLT domain, use the following commands. 1 Configure the port channel to be used for the VLT interconnect on a VLT switch and enter interface configuration mode. CONFIGURATION mode interface port-channel id-number Enter the same port-channel number configured with the peer-link port-channel command in the Enabling VLT and Creating a VLT Domain. 2 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: • 1 Gigabit Ethernet: enter gigabitethernet slot/port. • 10 Gigabit Ethernet: enter tengigabitethernet slot/port. • 40-Gigabit Ethernet: Enter fortyGigE slot/port. 3 Enter VLT-domain configuration mode for a specified VLT domain. CONFIGURATION mode vlt domain domain-id The range of domain IDs is from 1 to 1000. 4 Enter the port-channel number that acts as the interconnect trunk. VLT DOMAIN CONFIGURATION mode peer-link port-channel id-number The range is from 1 to 128. 5 Configure the IP address of the management interface on the remote VLT peer to be used as the endpoint of the VLT backup link for sending out-of-band hello messages. VLT DOMAIN CONFIGURATION mode back-up destination {ipv4-address] | ipv6 ipv6-address [interval seconds]} You can optionally specify the time interval used to send hello messages. The range is from 1 to 5 seconds. 6 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.
