642 Configuring the DHCP Mode
N0008589 3.3
If you must modify the DHCP default configuration on Business Communications Manager, make
sure configuration settings are consistent throughout the network and take the following into
consideration:
• If a change in the DHCP configuration resulted in a change in the IP addresses of a scope,
perform one of the following actions to ensure good system operation:
— Execute ipconfig/release and ipconfig/renew on each of the workstations. For Windows 95
and Windows 98, use the winipcfg .
— For clients that do not support ipconfig and winipcfg (for example, IP telephones), a reboot
is necessary to renew their IP addresses.
• If you made a change in the DNS server configuration or DNS name field, repeat the actions
stated in the previous step to ensure proper connectivity with the network.
• Always schedule a down time when making changes to the Business Communications
Manager DHCP server configuration to minimize impact on your network users.
Configuring the DHCP Mode
You can configure Business Communications Manager as your DHCP Server or as a DHCP Relay
Agent by setting the DHCP Mode.
• Choose DHCP server mode if you want Business Communications Manager to supply the IP
addresses to the devices on your network.
• Choose DHCP Relay Agent if you have a central DHCP Server on your corporate network and
you want Business Communications Manager to pass the DHCP traffic to and from the devices
on the LAN.
