Configuring Option 184 Parameters for the Client with Voice Service

To assign voice calling parameters along with an IP address to DHCP clients with voice service, you
need to configure Option 184 on the DHCP server. For information about Option 184, refer to
184.
If Option 55 in the request from a DHCP client contains Option 184, the DHCP server will return
parameters specified in Option 184 to the client. The client then can initiate a call using parameters in
Option 184.
Follow these steps to configure option 184 parameters in the DHCP address pool:
To do...

Specify the IP address of the
primary network calling processor
Specify the IP address of the
backup network calling processor
Configure the voice VLAN
Specify the failover IP address and
dialer string
Specify an IP address for the network calling processor before performing other configurations.

Configuring the TFTP Server and Bootfile Name for the Client

This task is to specify the IP address and name of a TFTP server and the bootfile name in the DHCP
address pool. The DHCP clients use these parameters to contact the TFTP server, requesting the
configuration file used for system initialization, which is called auto-configuration. The request process
of the client is described below:
1) When a router starts up without loading any configuration file, the system sets an active interface
(such as the interface of the default VLAN or a Layer 3 Ethernet interface) as the DHCP client to
