An Edge bridge profile makes an NSX Edge cluster capable of providing Layer 2 bridging to an overlay segment.
When you create an Edge bridge profile, you can specify one of the following failover modes:
- Preemptive
- When a failover occurs, the backup node becomes the active node. After the failed node recovers, it becomes the active node again.
- Non-Preemptive
-
When a failover occurs, the standby node becomes the active node. After the failed node recovers, it becomes the standby node.
You can manually set the standby edge node to be the active node by running the set l2bridge-port <uuid> state active CLI command on the standby edge node.
You can run this command only in the non-preemptive mode. Otherwise, an error occurs. In the non-preemptive mode, the command triggers an HA failover when applied on a standby node, and it is ignored when applied on an active node. For more information, see the NSX-T Data Center Command-Line Interface Reference.
Prerequisites
- An NSX Edge cluster is created in your NSX-T Data Center fabric and NSX Edge transport nodes are added to this cluster.
For example, in the previous topic, you created an Edge cluster named Cluster1 and added one NSX Edge transport node EN1 to this cluster.
Procedure
What to do next
You can now configure an Edge bridge on an NSX-T overlay segment by using this Edge bridge profile.
