Example

Following example shows that the VRF management is configured:

VRF-Name                         VRF-ID Interfaces
default                          0      Vl 1
management                       512    Ma 1/1 

Hence, the back-up destination command must be configured as:

DellEMC(conf-vlt-domain)#back-up destination <ip address> vrf management vrf-name
