Configuring DHCP
Business Communications Manager provides DHCP (Dynamic Host Configuration Protocol)
service to branch office clients. DHCP allows a network administrator to supervise and distribute
IP addresses from a central location. This service dynamically assigns IP addresses to branch
office computers or IP telephones, so you do not need to manually assign an IP address. It also
automatically assigns a new IP address if a device connects to a different place in the network.
This section includes information about:

DHCP configuration overview
To configure Business Communications Manager as your DHCP server, you must create a scope
of IP addresses for each LAN interface and then allocate a block of IP addresses to that scope. If
you already have a DHCP server then you need to set up Business Communications Manager as a
relay agent to that server.
You must define one DHCP scope for each LAN interface. For DHCP service, there are global
attributes that affect all scopes and there are attributes that are specific for each scope.
Caution:
Check with your network administrator before enabling DHCP. Enabling
DHCP on a network that already has a DHCP server can cause problems on the network.
Tip
Because Business Communications Manager retrieves
default
DHCP parameters from the
LAN interface parameters, you must configure a LAN interface before you configure the
DHCP server for that interface. For information on configuring a LAN interface, see
“Configuring the LAN resources” on page 667
.
Tip
Use the Business Communications Manager DHCP default configuration unless your
network does not allow it.
