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.
INTERFACE PORT-CHANNEL mode
no shutdown
5 Repeat Steps 1 to 4 on the VLT peer switch to congure 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 congure a VLT domain and enter VLT-Domain Conguration mode.
CONFIGURATION mode
vlt domain domain-id
The domain ID range is from 1 to 1000.
Congure 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 congure 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 Congure 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 Congure 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
lacp ungroup member-independent {vlt | port-channel port-channel-id}
LACP on VLT ports (on a VLT switch or access device), which are members of the virtual link trunk, is not brought up until the VLT
domain is recognized on the access device.
5 Repeat Steps 1 to 4 on the VLT peer switch to congure the IP address of this switch as the endpoint of the VLT backup link and to
congure the same port channel for the VLT interconnect.
