Avaya Vantage Installing And Administering page 49

The following is an example of a site-specific option that specifies:
• Two HTTPSRVR addresses,
• The ID of the Voice Virtual Local Access Network that the device must connect to,
• The ICMPDU parameter defines that Destination Unreachable messages must not be
transmitted.
HTTPSRVR="135.51.77.120,135.51.77.139",L2QVLAN=5,ICMPDU=0
The default DHCP option to set the site-specific configuration parameters is 242. You can also use
any option ranging between 128 and 254.
Note:
When the device receives DHCP ACK contents options 43 and 242, the device uses option
242.

Site-specific configuration parameters
The following table contains a list of site-specific configuration parameters that you can define for
the device.
Parameter Description
CAPTIVE_PO Specifies the URL of a captive portal server.
RTAL_SERV
ER
FILE_SERVE Specifies the list of URL for downloading image and configuration files. This parameter
R_URL has higher precedence over HTTPSRVR, HTTPPORT, HTTPDIR, TLSSRVR, TLSDIR,
and TLSPORT.
HTTPDIR 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>.
HTTPPORT Destination port for HTTP requests. The default value is 80.
HTTPSRVR IP addresses or DNS names of HTTP file servers used for downloading settings and
firmware files during startup.
Because the firmware files are digitally signed, TLS is not required for security. But
configuration files are not digitally signed, so it is recommended to use HTTPS servers for
storing configuration and firmware files.
