Status: Rejected
Type: Technical

Reported by: Imrane <[email protected]>
Date Reported: 2024-01-23
Rejected by: Eric Vyncke (IESG)

Section: 4.3.1

Original Text
-------------
Client identifier         MUST NOT     MUST NOT           MAY

Corrected Text
--------------
Client identifier         MUST NOT     MUST NOT           MUST NOT

Notes
-----
In the "Options" list in Table 3 ("Fields and options used by DHCP server"), the "Client identifier" option has "MUST NOT" for both DHCPOFFER and DHCPACK; however, for DHCPNAK, it has "MAY".

"Client identifier" should be a "MUST NOT" for DHCPNAK as well. 

It seems that the field should only be used by a client and never by a server, and if that's true for the OFFER and ACK, then it should be even more correct for the NAK.

"Vendor class identifier" has a MAY for all three messages, so maybe it was a typo in the previous option because of the repetitive input in the next one.
 --VERIFIER NOTES-- 
RFC 6842 has addressed this problem with more information than a simple errata.

I.e., the problem in RFC 2131 exists indeed but has been fixed.
