System Dhcp Support - Avaya 1600 Series Installation Manual

2.3.1 System DHCP Support

To change the system's DHCP settings:
1. Using IP Office Manager, retrieve the configuration from the system.
2. Select System.
3. Select the LAN1 or LAN2 tab depending on which of the system's LAN interfaces you want to use to support
H.323 extensions.
4. Select the LAN Settings tab.
5. If the DHCP Mode is set to Server, the Number of DHCP IP Addresses value set how many IP addresses the
system can issue. Those addresses use the IP Address of the system as the starting point.
6. Click the Advanced button or select the DHCP Pools tab if already visible.
a. The settings on this tab allow adjustment of the DHCP setting including adding multiple ranges of DHCP
numbers that the IP Office system can support. Note that address ranges outside those of the IP Office
systems own subnet may also require the creation of appropriate IP routes to ensure traffic routing between
the subnets.
·
Note: Changes to the DHCP pools do not require a reboot of the IP Office system. However, they will
cause a reboot of Avaya H323 and SIP telephones connected to the system. Non-Avaya IP phones are not
rebooted but may need to be manually restarted in order to obtain a valid address from the new pools
configuration.
b. If the Apply to Avaya IP Phone Only option is selected, the IP Office will act as a DHCP server for Avaya
phones only. This option cannot be used if also supporting 1100 Series and 1200 Series phones.
7. If the settings have been changed, save the configuration back to the system.
