Other Network Considerations - Avaya J169 Installing And Administering

Administering your phone
• DNS server address or addresses if applicable
As the LAN or System Administrator, you must also:
• Administer the DHCP server.
• Edit the configuration file on the applicable HTTP or HTTPS file server.

Other network considerations

SNMP enablement
The phone support SNMPv2c and Structure of Management Information Version 2 (SMIv2). The
phones also respond correctly to queries from entities that comply with earlier versions of SNMP,
such as SNMPv1. The phones respond to queries directed either at the MIB-II or the read-only
Custom MIB. Read-only means that you cannot change the values externally with network
management tools. H.323 Release 6.4 onwards, SNMP can be used to query the hardware
revisions on the phone.
You can restrict the IP addresses from which the phones accepts SNMP queries using the
SNMPADD parameter. You can also customize your community string with the SNMPSTRING
parameter.
Configuration of SNMPSTRING and SNMPADD can also be done using the Communication
Manager. The deskphones get this configuration after they register with the Communication
Manager.
Note:
SNMP is disabled by default. Administrators must start SNMP by setting the SNMPADD and
SNMPSTRING parameters appropriately.
For more information about SNMP and MIBs, see the IETF website. The Avaya Custom MIB
for the deskphones is a part of the software distribution file available for download on the
Avaya support site at http://www.avaya.com/support.
Ping and traceroute
All phones respond to a ping or traceroute message sent from the call server switch or any other
network source. The call server can also instruct the phone to originate a ping or a traceroute to a
specified IP address. The phone carries out that instruction and sends a message to the call
server indicating the results. For more information about administering an IP telephone system on
Communication Manager.
IP address and settings reuse
After you successfully register the phone with a call server, the phone saves the IP address and
the parameter values in the non-volatile memory of the phone. The phone can reuse the saved
parameters if the DHCP or HTTP/HTTPS server is not available for any reason after a restart. The
setting for the DHCPSTD parameter indicates whether to keep the IP address if no response is
received for lease renewal. If set to 1 (No) the phone strictly follows the DHCP standard with
