rotocol“ (SNMP) is a network protocol for controlling and moni-
toring network elements (e.g. router, server, switches, SIP stations etc.) via one central management
station/PC. In this process the protocol is controlling the communication between the monitored de-
vice and the monitoring station. SNMP describes the structure of the data packets as well as the
communication process.
The state of the respective device is detected by programs (so called “agents”) which are running di-
rectly on the monitored device (i.e. SIP station). By means of the SNMP, the “management station” is
able to communicate with this “agent” via network.
Management Information Base
The respective values (of a SIP station) read out by the management station, are described in a
“Management Information Base” (MIB). MIBs are description files in which the single values are listed
in table form. A MIB contain values specifically from one single SIP station only.
Using SNMP Function for SIP Stations
For use of the monitoring function via SNMP for SIP stations, following requirements have to be con-
sidered:
SNMPv2c
MIB
according
RFC 1213
Support for
IP-MIB
and
IF-MIB
Commend-MIB
Private Enterprise Number (PEN): 37568
(for download of the MIB see web link on
page 69
)
MIB Browser
By means of a MIB browser the values can be displayed. There are different providers for this type of
browser; some MIB browsers can be downloaded from the WWW as freeware.
In order to be able to use the SNMP function for the SIP station, the feature has to be activated as
well as the IP address of the management station has to be entered via the
web interface

Attention:
For reading out the MIB values, the “
SNMP Version 2
” has to be selected in the MIB browser.
