Servers, VLAN, and IP configuration

Configuration through DHCP

The Avaya J100 Series IP Phones obtain network and configuration information using DHCP
protocol. You can configure the DHCP server to provide the following information to the device:
®
• Avaya Aura
• IP address
• Subnet mask
• IP address of the router
• IP address of the HTTP or HTTPS file server
• IP address of the SNTP server
• IP address of DNS
You can configure the DHCP server to:
• Dynamically assign IP addresses to the Avaya J100 Series IP Phones.
• Provision device and site-specific configuration parameters through various DHCP options.

DHCP Site Specific Option

The phones support DHCP configuration option called Site Specific Option(SSON). Using this
parameter, custom parameters can be configured on the phone through a DHCP server. In the
DHCP DISCOVER, the phone requests for the DHCP Site-specific option (SSON), typically
configured in DHCP Option 242. To configure and respond to this request, configure the DHCP
server with proper data supplied in the offer for the value of this option. An example of such
configuration is as follows:
option avaya-option-242 L2Q=1,L2QVLAN=1212,httpsrvr=192.168.0.100.
Following parameters can be configured with this feature:
Parameter
ADMIN_PASS
WORD
HTTPDIR
July 2019
Session Manager address.
Description
Specifies the security string used to access local procedures.
The default is 27238. This is meant to replace PROCPSWD as it provides a more
secure password syntax.
Specifies the path to prepend to all configurations and data files the device might
request when starting up, that is, the path, relative to the root of the HTTP file server, to
the directory in which the device configuration and date files are stored. The path may
contain no more than 127 characters and may contain no spaces. HTTPDIR is the path
for all HTTP operations.
The command is SET HTTPDIR=<path>. In configurations where the upgrade and
binary files are in the default directory on the HTTP server, do not use the
HTTPDIR=<path>.
