Concept Guide

CONFIGURATION mode
interface port-channel id-number
Enter the same port-channel number congured with the peer-link port-channel command as described in Enabling VLT and
Creating a VLT Domain.
NOTE: To be included in the VLTi, the port channel must be in Default mode (no switchport or VLAN assigned).
2 Remove any IP address from the interface if already present.
INTERFACE PORT-CHANNEL mode
no ip address
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:
• For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport]
information.
• For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
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 congure 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 congure a VLT domain and enter VLT-domain conguration mode.
CONFIGURATION mode
vlt domain domain-id
The domain ID range is from 1 to 1000.
Congure 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 congure 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 Congure 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-address} [interval seconds] {vrf [management vrf-
name | vrf-name]}
