— Execute ipconfig/release and ipconfig/renew on each of the workstations. For
Windows 95 and Windows 98, use the winipcfg.

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 BCM DHCP server configuration
to minimize impact on your network users.
Configuring the DHCP Mode
You can configure BCM as your DHCP Server or as a DHCP Relay Agent by setting the DHCP
Mode.
• Choose DHCP Server mode if you want BCM to supply the IP addresses to the devices on
your network.
• Choose DHCP RelayAgent if you have a central DHCP Server on your corporate network and
you want BCM to pass the DHCP traffic to and from the devices on the LAN.
To set the DHCP Mode
1 Click Configuration > Data Services > DHCP Server.
The DHCP Settings panel appears.
2 Select DHCP Server or DHCP RelayAgent from the DHCP Mode drop-down list.
The default is DHCP Server.
