SNMP (Simple Network Management Protocol) is a standard network protocol that allows the monitoring
and management of data devices across a network.
An SNMP agent can be built into network devices such as routers and hubs. An SNMP manager
application (for example CastleRock or HP OpenView) can then communicate with those devices.
This communication can be:
•
Polling: Supported by IP Office 2.0 and above
Some SNMP manager applications send out polling messages to the network. They then record
the responds of any SNMP enabled devices (agents). This allows the manager to create a
network map and to raise an alarm when devices previously present do not respond.
•
Most SNMP manager applications can also do simple IP address polling to locate non-
SNMP enabled devices. However this method of polling does not identify the device type
or other information.
•
SNMP polling including details about the responding device. For example an IP Office
control unit's response includes the control unit type, level of software, routing table
information, up time, etc.
•
Traps: Supported by IP Office 2.0 and above
When certain events occur, a devices SNMP agent can send details of the event to the SNMP
manager. This is called an SNMP 'trap'. These appear in the event log of the SNMP manager.
Most SMNP manager's can be configured to give additional alerts in response to particular traps.
•
Management: Not supported by IP Office 2.0 and above
Some SNMP agents support device management and configuration changes through the SNMP
manager interface.
IP Office 2.0 and above allows IP Office Control Units to act as read-only SNMP v1 agents. It can
include the sending of events traps to up to two different SNMP manager addresses.
•
IP Office 3.2 supports the use of SMTP to email SNMP alarms. This allows the IP Office's SNMP
alarms to be used without having to setup an SNMP manager application.
IP Office SNMP operation has been tested against Castle Rock SNMPc-EE 5.1.6c and HP OpenView
Network Node Manager 6.41.
•
A MIB file exists for the SNMP monitoring of Avaya 4600 and 5600 Series IP phones. The MIB
file can be obtained from the Avaya support website (http://support.avaya.com).
•
The Avaya IP DECT system can also be monitored using SNMP. Refer to the IP DECT
Installation manual.
