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 following scenarios are

 

 

possible:

 

 

If a boot server value is stored in flash memory and the

 

 

value is not “0.0.0.0”, then the value stored in flash is used.

 

 

Otherwise the phone sends out a DHCP INFORM query.

 

 

- If 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.

 

 

- If no alternate DHCP server responds, the INFORM query

 

 

process will retry and eventually time out.

 

 

 

 

2=Static

The phone will use the boot server configured through the

 

 

Server Menu. For more information, refer to the next section,

3=Custom+Option

The phone will first use the custom option if present or use

 

66

Option 66 if the custom option is not present.

 

 

If the DHCP server sends nothing, the following scenarios are

 

 

possible:

 

 

If a boot server value is stored in flash memory and the

 

 

value is not “0.0.0.0”, then the value stored in flash is used.

 

 

Otherwise the phone sends out a DHCP INFORM query.

 

 

- If 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. 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.

 

 

- If no alternate DHCP server responds, the INFORM query

 

 

process will retry and eventually time out.
