Encapsulated Vendor Specific Option
553-3001-204 Preliminary 0.10 August 2000
Configuration of the DHCP server
All i2004 Internet Telephones fill in the Class ID option of the DHCP
Discovery and Request messages with the null-terminated, ASCII-encoded
string Nortel-i2004-A, where A identifies the version number of the i2004
Internet Telephone.
The Class Identifier Nortel-i2004-A must be unique in the DHCP server
domain.
The following definition describes the Nortel i2004 specific, Encapsulated
Vendor Specific option. This option must be encapsulated in a DHCP Vendor
Specific Option (Refer to RFC 1533) and returned by the DHCP server as part
of each DHCPOFFER and DHCPACK message for the i2004 to accept these
messages as valid. The i2004 will extract the relevant information out of this
option and use it to configure the connect server IP address, the port number
(4100), a command value of one, and retry count for the primary and
secondary connect server.
