Determining The Status For The Dhcp Server; Using The Bcm As A Standalone Dhcp Server; Dhcp For Ip Sets - Nortel BCM50 Configuration Manual

492 Chapter 67 DHCP configuration with router

Determining the status for the DHCP server

By default, the DHCP server on the BCM is set to enabled-automatic. This means that it will
automatically detect whether there is already a DHCP server on the network. This feature covers
all of the following scenarios:
• The network is already using DHCP from another server, but the network contains devices that
require the BCM DHCP server, such as Nortel IP Phones.
• The network is already using DHCP from another server, and the network does not contain any
devices that require the BCM DHCP server.
• The network does not have a DHCP server, and the BCM DHCP server is required to provide
IP addresses to all DHCP clients.
If your network matches one of these configuration scenarios, ensure that the DHCP status is set to
enabled-automatic.
If the network configuration does not match any of these scenarios, you can either disable the
DHCP server, set the DHCP server to respond to requests from IP phones only, or set the DHCP
server to respond to requests from all DHCP clients.

Using the BCM as a standalone DHCP server

If there is no DHCP server on the network, the BCM will use the following as a default IP
configuration:
• IP Address: 192.168.1.2
• Subnet Mask: 255.255.255.0
• Gateway: 192.168.1.1
The DHCP server on the BCM will provide all necessary information to DHCP clients on the
networks.

DHCP for IP sets

In addition to IP address information, IP sets require additional information if they are set to Full
DHCP mode. This information includes the IP address, port number, action, and retry count for
both the primary and secondary terminal proxy server.
