Configuring DHCP for 9600 Series IP Telephones

To administer DHCP option 242, make a copy of an existing option 176 for your 46xx IP Telephones. You can then either:

Only the following parameters can be set in the DHCP site-specific option for 96xx telephones, although most of them can be set in a 46xxsettings.txt file as well.

Table 6:  Parameters Set by DHCP  
Parameter
Description
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.
HTTPSRVR
IP Address(es) or DNS name(s) of HTTP file server(s) used to download 96xx telephone software files. The files are digitally signed, so TLS is not required for security.
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 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 except for BRURI.
STATIC
Controls whether to use a manually-programmed file server or CM IP Address instead of those received via DHCP or a settings file. If a manually-programmed file server IP Address is to be used, STATIC must be set via DHCP.
MCIPADD
CM server(s) IP Address(es) or DNS name(s). 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 via DHCP improves reliability if the file server is not available due to server or network problems.
DOT1X
Controls the operational mode for 802.1X. The default is 0 (pass-through of multicast EAPOL messages to an attached PC, and enable Supplicant operation for unicast EAPOL messages).
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.
LOGLOCAL
Controls the severity level of events logged in the SNMP MIB. The default is 7.
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 (CRAFT).
PROCSTAT
Controls whether local (Craft) procedures are allowed. The default is 0 (access to all administrative options is allowed).
SNMPADD
Allowable source IP Address(es) for SNMP queries. The default is " " (Null).
SNMPSTRING
SNMP community name string. The default is " " (Null).
VLANTEST
Controls the length of time the telephone tries DHCP with a non-zero VLAN ID. When the interval is exceeded, the telephone records the VLAN ID so that it is not used again, and DHCP continues on the default VLAN. The default is 60 seconds.
