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:
• 1-Gigabit Ethernet: Enter gigabitethernet slot/port.
• 10-Gigabit Ethernet: Enter tengigabitethernet slot/port.
• 40-Gigabit Ethernet: Enter fortyGigE slot/port.
4 Ensure that the port channel is active.
INTERFACE PORT-CHANNEL mode
no shutdown
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:
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 {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.
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) After you configure a VLT domain on each peer switch and connect (cable) the two VLT peers
on each side of the VLT interconnect, the system elects a primary and secondary VLT peer device (see
Primary and Secondary VLT Peers). To configure the primary and secondary roles before the election
