Enter the same port-channel number configured with the peer-link port-channel command as
described in Configuring VLT and Connecting 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 an IP address from the interface.
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:
• 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 configure the VLT interconnect.
Configuring a VLT Backup Link
To configure a VLT backup link, use the following command.
1. Specify the management interface to be used for the backup link through an out-of-band
management network.
CONFIGURATION mode
interface managementethernet slot/ port
Enter the slot (0-1) and the port (0).
2. Configure an IPv4 address (A.B.C.D) or IPv6 address (X:X:X:X::X) and mask (/x) on the interface.
MANAGEMENT INTERFACE mode
{ip address ipv4-address/ mask | ipv6 address ipv6-address/ mask}
This is the IP address to be configured on the VLT peer with the back-up destination command.
3. Ensure that the interface is active.
MANAGEMENT INTERFACE mode
no shutdown
4. Repeat Steps 1 to 3 on the VLT peer switch.
To set an amount of time, in seconds, to delay the system from restoring the VLT port, use the delay-
restore command at any time. For more information, refer to VLT Port Delayed Restoration.
