Before changing the Huawei network configuration, an engineer investigates: A campus switches the active DHCP server to a data center but the VLANIF relay points to the retired server IP. Which diagnostic check should be performed first?
Inspect VLANIF relay configuration, DHCPDISCOVER/OFFER packets and server scope. This check isolates the suspected cause before an unsafe change.

Successful verification is: Clients obtain a valid address lease, gateway and DNS options from the authorized remote DHCP server.

This check would diagnose SNMPv3 secure network monitoring, but would not first isolate the described DHCP relay to remote server. Begin with: Inspect VLANIF relay configuration, DHCPDISCOVER/OFFER packets and server scope.
