3C10165D E1 Digital Line Cards and 3C10116D T1 Digital Line Cards do

not support DHCP option 184. If your DHCP server is set up to use option

184, you must still manually configure these digital line cards. See the

NBX Administrator's Guide for more information.

RFC 2132 (DHCP Options and BOOTP Vendor Extensions) defines vendor

specific options that allow you to configure the server to send locally

defined information to DHCP clients. NBX system devices support option

184. If you create and activate option 184 on your DHCP server, and use

it to specify the IP address of the NCP, you do not need to manually

configure the address on the NBX devices. For an example of how to

configure a DHCP server for option 184, see Appendix C, "Configuring

Option 184 on a Windows 2000 DHCP Server" in the NBX

Administrator's Guide.
