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.
Reconguring the Default VLT Settings (Optional)
To recongure the default VLT settings, 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 is from 1 to 1000.
2 After you congure 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. To congure the primary and secondary roles before the election process,
use the primary-priority command. Enter a lower value on the primary peer and a higher value on the secondary peer.
If the primary peer fails, the secondary peer (with the higher priority) takes the primary role. If the primary peer (with the lower
priority) later comes back online, it is assigned the secondary role (there is no preemption).
3 (Optional) When you create a VLT domain on a switch, Dell EMC Networking OS automatically creates a VLT-system MAC address
used for internal system operations.
