Configuring Gateways for the DHCP Client
Gateways are necessary for DHCP clients to access servers/hosts outside the current network segment.
After you configure gateway addresses on a DHCP server, the DHCP server provides the gateway
addresses to DHCP clients as well while assigning IP addresses to them.
You can configure gateway addresses for global address pools on a DHCP server. Currently, you can
configure up to eight gateway addresses for a DHCP address pool.
Follow these steps to configure gateways for the DHCP client:
To do… Use the command… Remarks
Enter system view system-view —
Enter DHCP address pool view
dhcp server ip-pool
pool-name
—
Configure gateway addresses
for DHCP clients gateway-list
ip-address&<1-8>
Required
By default, no gateway address
is configured.
Configuring BIMS Server Information for the DHCP Client
A DHCP client performs regular software update and backup using configuration files obtained from a
branch intelligent management system (BIMS) server. Therefore, the DHCP server needs to offer
DHCP clients the BIMS server IP address, port number, shared key from the DHCP address pool.
Follow these steps to configure BIMS server information for the DHCP client:
To do… Use the command… Remarks
Enter system view system-view —
Enter DHCP address pool view
dhcp server ip-pool
pool-name
—
Configure the BIMS server
information to be assigned to
the DHCP client bims-server ip ip-address
[ port port-number ] sharekey
key Required
By default, no BIMS server
information is configured.
Configuring Option 184 Parameters for the Client with Voice Service
Option 184 is a reserved option, and the information it carries can be customized. You can define four
sub-options for this option after enabling the DHCP server. Thus, besides obtaining an IP address, the
DHCP client with voice services can obtain voice related parameters from the DHCP address pool.
Basic concept
The four sub-options of Option 184 mainly carry information about voice. The following lists the
sub-options and the carried information:
z Sub-option 1: IP address of the network call processor (NCP-IP).
z Sub-option 2: IP address of the alternate server (AS-IP).
z Sub-option 3: Voice VLAN configuration.
