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.
6. Repeat Steps 1 to 4 on the VLT peer switch to congure the IP address of this switch as the endpoint of the VLT backup link
and to congure the same port channel for the VLT interconnect.
Conguring a VLT Backup Link
To congure 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. Congure 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 congured on the VLT peer with the back-up destination command.
3. Ensure that the interface is active.
MANAGEMENT INTERFACE mode
no shutdown
4. Congure a VLT backup link using the IPv4 or IPv6 address of the VLT peer’s management interface.
MANAGEMENT INTERFACE mode
back-up destination {ip address ipv4-address/ mask | ipv6 address ipv6-address/ mask}
5. Repeat Steps 1 to 4 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.
Conguring a VLT Port Delay Period
To congure a VLT port delay period, use the following commands.
1. Enter VLT-domain conguration mode for a specied VLT domain.
CONFIGURATION mode
vlt domain domain-id
The range of domain IDs from 1 to 1000.
2. Enter an amount of time, in seconds, to delay the restoration of the VLT ports after the system is rebooted.
CONFIGURATION mode
delay-restore delay-restore-time
The range is from 1 to 1200.
The default is 90 seconds.
