Replace a Device with a Different Configuration

You can replace a device when the configuration on the old device does not match the configuration on the new device.

1. Remove the old device from EFA.
   

   efa fabric device remove –name <Fabric name> --ip <IP address of the device>

   This command removes the device (decommissioned from the Fabric), cleans up all relevant neighbors, and cleans up the sub-configurations from MCT and BGP configurations.
2. Add the new device to EFA.
   

   dca fabric device add-bulk –name <Fabric name> --leaf <IP address of the 
   device if it is a leaf> --spine <IP address of the device if it is a spine> 
   --super-spine <IP address of the device if it is a super spine>

3. Verify that the device shows up in the Fabric.
   

   efa fabric show

4. (Optional) View the cause of an application or device error.
   

   efa fabric error show

5. (Optional) View the cause of a configuration refresh.
   

   efa fabric debug config-gen-reason

6. Configure the Fabric.
   

   efa fabric configure -name <Fabric name>

7. Rerun all Tenant configurations.
