Result
You can set only the following parameters in the DHCP site-specific option for IP Deskphones,
although most of them can be set in a 46xxsettings.txt file as well.
Table 7: Parameters Set by DHCP in a Site-Specific Option
Parameter
Description
DNSSRVR
Specifies the DNS server IP address or addresses.
DOMAIN
Specifies the string that is appended to DNS names in parameter values when
they are resolved into IP addresses.
DOT1X
Controls the operational mode for 802.1X. The default is 0, for pass-through of
multicast EAPOL messages to an attached PC, and enables Supplicant operation
for unicast EAPOL messages.
DOT1XSTAT
Controls 802.1X Supplicant operation.
HTTPDIR
Specifies the path name to prepend to all file names used in HTTP and HTTPS
GET operations during startup. (0 to 127 ASCII characters, no spaces.) The
command is
SET HTTPDIR myhttpdir
. The path relative to the root of the TLS or
HTTP file server where IP Deskphones 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 through 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 except for BRURI.
HTTPPORT
Specifies the TCP port number to download the HTTP file.
HTTPSRVR
Specifies the IP addresses or DNS names of HTTP file servers used to download
IP Deskphones software files. The 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 which sends Destination Unreachable
messages for closed ports used by traceroute.
ICMPRED
Controls whether ICMP Redirect messages are processed. The default is 0 which
redirects messages that are not processed.
L2Q
specifies the 802.1Q tagging mode. The default is 0 which signifies automatic.
L2QVLAN
VLAN ID of the voice VLAN. The default is 0.
LOGLOCAL
Controls the severity level of events logged in the SNMP MIB. The default is 7.
MCIPADD
CM servers IP addresses or DNS names. If there are too many addresses or
names to include all of them in the DHCP site-specific option, include at least one
from each major system. Then set MCIPADD again in the 46xxsettings.txt file with
the complete list of addresses. Providing a subset of the addresses through DHCP
improves reliability if the file server is not available due to server or network
problems.
NDREDV6
NDREDV6 IPv6 only. Controls whether IPv6 Neighbor Discovery Redirect
messages will be processed.
