DHCP Server Administration
Issue 1 January 2008 51
Table 7: Parameters Set by DHCP
Parameter Description
HTTPDIR Specifies the path name to prepend to all file names used in HTTP GET
operations during startup. (0 to 127 ASCII characters, no spaces.) The command
is “GET HTTPDIR myhttpdir”. The path (relative to the root of the HTTP file
server) where 96xx telephone files are stored. If an Avaya file server is used to
download configuration files over TLS, but a different server is used to download
software files via HTTP, set the path of the Avaya server in the DHCP
site-specific option, and set HTTPDIR again in the 46xxsettings.txt file with the
appropriate path for the second server. HTTPDIR is the path for all HTTP
operations.
HTTPPORT Destination port for HTTP requests (0-65535, default is 80).
HTTPPROXY IP or DNS address of the HTTP server for SCEP. 0 to 255 characters in dotted
decimal or DNS name format followed by a colon and port number. The colon
and port number are optional. If this parameter is not null, this (proxy) transport
address is used to set up the HTTP connection as the transport protocol for
SCEP.
HTTPSRVR IP Address(es) or DNS name(s) of HTTP file server(s) used to download
telephone files.
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 (sends Destination Unreachable messages for
closed ports used by traceroute).
ICMPRED Controls whether ICMP Redirect messages are processed. The default is 0
(redirect messages are not processed).
L2Q 802.1Q tagging mode. The default is 0 (automatic).
L2QVLAN VLAN ID of the voice VLAN. The default is 0.
LOGSRVR Syslog server IP or DNS address.
MTU_SIZE Maximum transmission unit size. Used to accommodate older Ethernet switches
that cannot support the longer maximum frame length of tagged frames (since
802.1Q adds 4 octets to the frame).
PHY1STAT Controls the Ethernet line interface speed. The default is 1 (auto-negotiate).
PHY2STAT Controls the secondary Ethernet interface speed. The default is 1
(auto-negotiate).
PROCPSWD Security string used to access local procedures. The default is 27238.
PROCSTAT Controls whether local procedures are enabled. The default is 0 (enabled).
SIPPROXYSRVR SIP proxy/registrar server IP or DNS address. (0 to 255 characters; zero or one
IP Address in dotted decimal or DNS name format, separated by commas
without any intervening spaces.) The default is null.
SNTPSRVR List of SNTP server IP or DNS address(es) used to retrieve date and time via
SNTP
TLSDIR Used as path name that is prepended to all file names used in HTTPS get
operations during initialization (0-127 character string).
TLSPORT Destination TCP port used for requests to https server (0-65535). The default is
443.
TLSSRVR IP Address(es) or DNS name(s) of Avaya file server(s) used to download
configuration files.
Note: Transport Layer Security is used to authenticate the server.
VLANTEST Number of seconds to wait for a DHCPOFFER on a non-zero VLAN. The default
is 60 seconds.
