: Specifies all interface address pools.
Description
Use the
dhcp server voice-config
command to enable the DHCP server to assign IP addresses with
Option 184 and its sub-options from the specified interface address pool.
Use the
undo dhcp server voice-config
command to disable the DHCP server from assigning IP
addresses with Option 184 and its sub-options from the specified interface address pool.
The DHCP server answers Option 184 and the corresponding sub-options only after the DHCP client
requests for Option 184.
Before configuring other sub-options, you must configure the sub-option
ncp-ip
; otherwise other
sub-options do not take effect.
By default, a DHCP server interface address pool does not assign Option 184 and the corresponding
sub-options to the client.
