NSTALLATION
The Windows 2003 server expects a valid MAC address in the MAC
address field. The Vendor Class Identifier strings (converted to
hexadecimal format) are longer than a normal MAC address so you may
see this warning message:
“The Unique Identifier you have entered may
not be correct. Do you want to use this identifier anyway?” It is safe to
ignore this message.
Configuring DHCP Options for a Reservation
For each IP address reservation that you have created, follow the
procedures in this section to configure DHCP options 12, 60, 66, and 67.
Option 12 — Host Name
The host name option allows the DHCP server to supply a name for the
branch office VCX server or the Media Gateway that has sent the DCHP
request. 3Com suggests that you choose each host name to indicate the
office in which the host resides.
