Configuring DHCP server

The G450 supports DHCP server. DHCP server is a protocol for automatically assigning IP
addresses and other configuration parameters to clients on a TCP/IP network. DHCP server
minimizes the maintenance of a network of, among other things, IP telephones and PCs, by
removing the need to assign and maintain IP addresses and other parameters for each device
on the network individually.
Since a DHCP server can be configured on the G450, local branch devices are not dependant
on receiving configuration parameters over the WAN from a remote DHCP server and,
therefore, can be assigned IP configuration parameters in case of WAN failure.
The G450 supports the following DHCP server features:
Up to 32 DHCP pools
●
Up to 120 users
●
Up to 256 IP addresses for all DHCP pools together
●
Automatic and reservation pools
●
Standard DHCP options and IP phone and wireless special options
●
Vendor specific information option
●
DHCP relay packets
●
Global statistics
●
Syslog/traps for special events
●
The Avaya G450 Media Gateway can function as a DHCP server, as a DHCP relay, or both
simultaneously, with each interface configured in either DHCP server mode or DHCP relay
mode. For example, you can configure the G450 to provide DHCP service to voice devices
while DHCP requests by data devices are routed to a central remote DHCP server using DHCP
relay.
The Avaya G450 Media Gateway can function as a DHCP server or as a DHCP client, or both
simultaneously. For information about configuring DHCP client on the G450, see
DHCP client on page 199.
