Adding and Deleting Management Subinterfaces

Use the EFA CLI to add and delete management sub-interfaces.

1. Run the following commands to add a management sub-interface:
   

   efa mgmt subinterface create --name <name> --ip-address <IP Subnet> --vlan-id <VLAN>

   • If a management network with the same name exists, the system informs you about this and the operation fails.
   • The changes made by this operation span across three different components:
     • Sub-interface creation under the physical NIC
     • Keepalived configuration changes (for high-availability deployments)
     • Ingress controller changes
   • If any of the operations to the component fails, it is marked as a failed operation and the configurations return to the previous state.
2. Run the following commands to delete a management sub-interface:
   

   efa mgmt subinterface delete --name <name>

   If a management network with the name exists, it is deleted. Otherwise, the correct response is provided in the command output.

   For more information about the commands, see the Extreme Fabric Automation Command Reference, 2.5.0 .
