IES-1248-51 User's Guide
The Agent Information field that the IES-1248-51 adds also contains an "Agent Remote-ID
sub-option" of information that you specify.
The following figure shows the format of the Agent Remote ID sub-option. The 2 in the first
field identifies this as an Agent Remote ID sub-option. The length N gives the total number of
octets in the Agent Information Field. Then there is the number of the port (in plain text
format) upon which the DHCP client request was received. The next field (B in the figure) is 0
to 23 bytes of optional information that you specify. This is followed by the name and
telephone number configured for the ADSL port. The port number, optional information (B in
the figure), ADSL name and ADSL telephone number fields are separated by forward slashes.
