Configuring DHCP server

The G250/G350 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 G250/G350, 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 G250/G350 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 G250/G350 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 G250/G350 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 G250/G350 Media Gateway can function as a DHCP server or as a DHCP client, or
both simultaneously. For information about configuring DHCP client on the G250/G350, see
