2.2.2 DHCP Options
WAN Mode of the phone must be DHCP to use DHCP Option.
There are four options available for DHCP Option: DHCP option 66, DHCP option 43, Custom
DHCP Option and DHCP Option Disable.
Custom DHCP Option’s setting range is 128~254. DHCP Option Disable
means closing DHCP Option.
Restart the phone or wait for a renewal of DHCP server after setting, then the phone will request for
option information from the DHCP server. If the server replies the option information you requested, you
will see the corresponding option information from the capture package replied from the server. Filter
“bootp” and view the ACK package to get the URL which the phone will parse.
When obtaining an application parameter of Auto Provision through DHCP Option mode, the user can
optionally choose one option. For example, If DHCP option 43 is selected, it will have the following field
values in the “DHCP discover message” and “DHCP request message” which terminal sends to the
server.
Option: (t=55,l=7) Parameter Request List
Option: (55) Parameter Request List
