  2. CAPWAP base specification defined a DHCP option The DHCP option was identified as being inconsistent with other DHCP options With the guidance of the DHC WG Chair, we agreed to create a separate Internet-Draft (available as draft-calhoun-dhc-capwap-ac-option-00.txt) The DHC WG Chair stated the current spec is acceptable. The CAPWAP Chairs recently decided the document should be a CAPWAP WG item (will be renamed to draft-ietf-capwap-dhc-ac-option-00.txt) History

If configured with a (list of) CAPWAP AC address(es), a DHCPv4 server SHOULD send the client the CAPWAP AC DHCPv4 option, even if this option is not explicitly requested by the client. A CAPWAP WTP, acting as a DHCPv4 client, receiving the CAPWAP AC DHCPv4 option MAY use the (list of) IP address(es) to locate AC. The CAPWAP protocol provides guidance on the WTP's discovery process.

If configured with a (list of) CAPWAP AC address(es), a DHCPv6 server SHOULD send the client the CAPWAP AC DHCPv6 option, even if this option is not explicitly requested by the client.
