DHCP site-specific option

You can set the values of site-specific configuration parameters through a DHCP option. The default
DHCP option to set the site-specific configuration parameters is 242. You can also use any option
between 128 to 254. Whichever option you select to specify the site-specific configuration, you must
specify that option number in the Site-Specific Option Number (SSON) parameter. You can set the
SSON parameter through the device interface.
Following is an example of the DHCP 242 option string that specifies the HTTPSRVR and the Voice
VLAN that the device must connect to.
HTTPSRVR=10.138.251.67,L2QVLAN=1104
The following table lists the site-specific configuration parameters that you can define for the device.
Parameter Description
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 is 80.
HTTPSRVR IP addresses or DNS names of HTTP file servers used for downloading settings, language,
and firmware files during startup.
The firmware files are digitally signed, so TLS is not required for security.
ICMPDU Controls the extent to which ICMP Destination Unreachable messages are sent in response
to messages sent to closed ports so as not to reveal information to potential hackers. The
default is 1, that is sends Destination Unreachable messages for closed ports used by
traceroute.
ICMPRED Controls whether ICMP Redirect messages are processed. The default is 0, that is, redirect
messages are not processed.
L2Q 802.1Q tagging mode. The default is 0 for automatic.
L2QVLAN VLAN ID of the voice VLAN. The default is 0.
PHY1STAT Controls the Ethernet line interface speed. The default is 1 for auto-negotiate.
