Specifying a Locally Configured IP Address

Dynamic Host Configuration Protocol (DHCP) is used to dynamically allocate and assign IP addresses. DHCP allows you to move network devices from one subnet to another without administrative attention. You can choose to enable DHCP if a DHCP server is present. If you disable DHCP, you must enter an IP address (the locally configured IP address if not assigned by a DHCP server), subnet mask (used to partition the IP address into a network and host identifier), and gateway (IP address of the default gateway the system uses).

Configuring Avaya Systems Using DHCP

If an Avaya video communications system obtains its IP address using DHCP (the default), it can accept an option from the DHCP server that specifies a location and file from which the system can obtain configuration information. The file can be located on a web server, trivial file transfer protocol (TFTP) server, or file transfer protocol (FTP) server. Each time the system boots, it attempts to fetch the configuration file specified by the option. If the configuration file has changed since the last time it was applied, the system applies the configuration file before the boot process continues. The following prerequisites must be met to enable this feature:

•The DHCP preference in Administrator Preferences : Network : General on the Avaya system must be set to Enabled.

•An Avaya system accepts site-specific option 157 for this feature. You must configure this option on the DHCP server.

Note: If you configure a system using DHCP option 157 and specify a TFTP server as the source from which to obtain the configuration file, the system accepts the download through port 5351. Ensure that firewalls between the system and the TFTP server are configured to allow the download through this port.
