5. Enter the IP address of the peer OVSDB server.
peer-ovsdbserver-ip ovsdb-IP-address
The peer OVSDB server is the peer VLT device.
6. Enter the fail mode.
VxLAN INSTANCE mode
fail-mode secure
7. Enable the VxLAN instance.
VxLAN INSTANCE mode
no shutdown
NOTE: Dell EMC Networking recommends the non-secure fail mode if you are configuring VxLAN for a VLT setup and
use a physical L3 link for peer OVSDB connectivity. Also using of controller connected IP address for peer OVSDB
connectivity leads to double failure, when connected link fails..
Configuring VLT for NSX-based VxLAN
After configuring NSX-based VxLAN on the device, configure VLT. To configure VLT for NSX-based VxLAN, follow these steps:
1. Enable VLT on a switch, then configure a VLT domain and enter VLT-domain configuration mode.
CONFIGURATION mode
vlt domain domain-id
The domain ID range is from 1 to 1000.
Configure the same domain ID on the peer switch
2. Configure 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
3. Configure 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. Assign VLT system MAC address.
VLT DOMAIN CONFIGURATION mode
system-mac mac-address mac-address
5. Enable peer routing.
VLT DOMAIN CONFIGURATION mode
peer-routing
6. Configure the primary priority.
VLT DOMAIN CONFIGURATION mode
primary-priority value
The priority values are from 1 to 65535. The default is 32768.
7. Configure the unit ID.
unit-id
NOTE:
For controller-based VxLAN, the VLT unit ID is mandatory.
8. Repeat these steps on the VLT peer switch.
VLT configuration:
DellEMC#show runn vlt

vlt domain 100
peer-link port-channel 1
back-up destination 38.0.0.1
