Sample DHCP Configuration File (continued)
The previous line defines the vendor class identifier string sent by the VCX
server in the branch office when it sends a DHCP request. The string for
BRANCH_CALLP depends on the VCX software release. For example, a
VCX server running release 7.0.3c would use 3Com-VCX-7200-7.0.3c as
the vendor class identifier string.
The previous line defines the vendor class identifier string sent by the
PSTN gateway. The string is the same regardless of whether the PSTN
gateway is a separate unit or is contained within the same box as the VCX
server.
"3Com-Phone-2101";
"3Com-Phone-2102";
"3Com-Phone-3100";
"3Com-Phone-3101";
"3Com-Phone-3102";
"3Com-Phone-3103";
The previous set of lines define vendor class identifier strings for 3Com
telephones. These strings are used by the match statement in each of the
class statements. This file includes a sample line for each possible
telephone type. In your dhcpd.conf file, include the lines for the
telephone types that are in the branch office.
The previous line creates an option space called phone-184. The name of
this option space is your choice. The space is intended to contain
vendor-specific options related to DHCP Option 184, as defined in RFC
2132.
The previous line encapsulates all of the attributes of option 184 under
the name "phone-184." There are three separate attributes associated
with option 184 and by encapsulating them, the attributes can be
delivered to DHCP clients (telephones) in a single package.
The previous line defines option code 1 as an IP address. In this case the IP
address is for the branch office VCX server. Telephones in a branch office
normally obtain call processing services from this server.
