Boot Server (continued)
1=Custom
The phone will look for the option number specified by the Boot
Server Option parameter (below), and the type specified by
the Boot Server Option Type parameter (below) in the
response received from the DHCP server. If the DHCP server
sends nothing, the phone sends out a DHCP INFORM query
and the following scenarios are possible:
•
If no alternate DHCP server responds:
- The INFORM query process will retry and eventually time
out.
- The boot server value stored in flash will be used.
•
A single alternate DHCP server responds. This is
functionally equivalent to the scenario where the primary
DHCP server responds with a valid boot server value.
2=Static
The phone will use the boot server configured through the
Server Menu. For more information, refer to the following
section,
3=Custom+Option
66
The phone will first use the custom option if present or use
Option 66 if the custom option is not present. If the DHCP
server sends nothing, the phone sends out a DHCP INFORM
query and the following scenarios are possible:
•
If no alternate DHCP server responds:
- The INFORM query process will retry and eventually time
out.
- The boot server value stored in flash will be used.
•
A single alternate DHCP server responds.
- The phone prefers the custom option value over the
Option 66 value, but if no custom option is given, the phone
will use the Option 66 value. This is functionally equivalent
to the scenario where the primary DHCP server responds
with a valid boot server value.
