Here I will make example to show how to supervise the phone with SNMP.
1. Webpage -> Management -> Auto Provision -> SNMP Service
MIB Browser: MIB_Browser.zip
1. Introduction
SNMP is a standard network management protocol that is widely used on TCP/IP networks. It can be used in a network management system to monitor any exception on devices connected to the network. SNMP uses a polling mechanism and provides a basic function set, making it applicable to small-scale networks that are sensitive to speed and cost. Moreover, SNMP messages are carried in User Datagram Protocol (UDP) packets, which are supported by most network devices. In addition, SNMP allows management information exchange between any two devices on a network, allowing network administrators to query information and locate faults on any network nodes.
On the phone, SNMP Service allows administrator disable/enable this feature, set Get and Set Community string, and up to 4 SNMP Manager IP address.
2. Using SNMP
To configure SNMP via Web interface:
You could find SNMP settings on webpage → Management → Auto Provision → SNMP Service
The above image shows the needed settings of the SNMP feature.
- SNMP Service Enable: Yes
- SNMP Get Community: string within 32 characters
- SNMP Set Community: string within 32 characters
- SNMP Manager IP 1: IP address
The SNMP request from unknown IP or carries incorrect community string will be ignored.
