Parameters
ncp-ip ip-address: Specifies the IP address of the primary network calling processor.
as-ip ip-address: Specifies the IP address of the backup network calling processor.
voice-vlan vlan-id: Specifies the voice VLAN ID, in the range of 2 to 4094.
z disable: Disables the specified VLAN, meaning DHCP clients will not take this VLAN as their voice
VLAN.
z enable: Enables the specified VLAN, meaning DHCP clients will take this VLAN as their voice
VLAN.
fail-over ip-address dialer-string: Specifies the failover IP address and dialer string. The dialer-string is
a string of 0 to 39 characters, which can be 0 to 9, and “*”.
interface interface-type interface-number [ to interface-type interface-number ]: Specifies the DHCP
interface address pool (s).
all: 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.
Related commands: voice-config.
