Hello,
Starting with Cisco IOS XE Denali 16.1.x, a DHCP client that includes option 61 (used by DHCP clients to specify their unique client identifier) in their DHCP discover/offer packet must accept the response message with option 61 from the DHCP server/relay. A client that fails to accept the response message with option 61, is not in compliance with RFC 6842 and requires a firmware upgrade.
The question is if there is an IOS XE command, which turns off the RFC 6842 behavior and returns back to the old behavior, which means server MUST NOT return the 'client identifier' option to the client.
Best Regards,
Peter
