3 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:
• 10 Gigabit Ethernet: Enter tengigabitethernet slot/port.
• 40 Gigabit Ethernet: Enter fortygigabitethernet slot/port.
4 Ensure that the port channel is active.

5 Repeat Steps 1 to 4 on the VLT peer switch to configure the VLT interconnect.
Enabling VLT and Creating a VLT Domain
To enable VLT and create a VLT domain, use the following steps.
1 Enable VLT on a switch, then configure a VLT domain and enter VLT-Domain Configuration mode.
CONFIGURATION mode
vlt domain domain-id
The domain ID range is from 1 to 1000.
Configure the same domain ID on the peer switch to allow for common peering. VLT uses the domain
ID to automatically create a VLT MAC address for the domain. If you do not configure the system
explicitly, the system mac-address of the primary will be the VLT MAC address for the domain.
To disable VLT, use the no vlt domain command.
NOTE: Do not use MAC addresses such as “reserved” or “multicast.”
2 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 ip-address [interval seconds]
Optionally, specify the time interval used to send hello messages. The range is from 1 to 5 seconds.
3 Configure the port channel to be used as the VLT interconnect between VLT peers in the domain.
VLT DOMAIN CONFIGURATION mode
peer-link port-channel id-number
4 (Optional) Prevent a possible loop during the bootup of a VLT peer switch or a device that accesses the
VLT domain.
CONFIGURATION mode
