The Simple Network Management Protocol (SNMP) is used in network management systems to monitor attached hardware for changes in operation activity. SNMP provides a standardized approach to monitoring and managing network systems.
For information on configuring your TMedia product to use the SNMP protocol, see the section labeled "Related Tasks".

TelcoBridges and SNMP

TelcoBridges offers basic support for SNMP versions 1, 2, and 3. Toolpack supports SNMP V2 and V3 since release 2.5.80 (see TMG-CONTROL version history). More specifically, this grants users the ability to remotely poll (or GET) system variables, known as Managed Objects, which are represented in files known as MIB modules. TelcoBridges currently offers polling on standard MIB modules (RTP, SONET, DS1, DS3, ISDN, etc...) and on the TelcoBridges privately defined module (TB-MIB).


The following procedures should be used to support SNMP v1 ONLY for Toolpack system previous to 2.5.80:

SNMP traps

The SNMP traps module of TelcoBridges products monitor the operation status of some MIBS OIDs and generates notifications when the states change. The default monitoring polling period is set to 1 minute. This value can be modified in the tbSnmpAgent configuration.

IF-MIB SNMP Trap/Notification (see RFC1573.txt)

Trap Name OID OBJECTS RELEASE
linkDown 1.3.6.1.6.3.1.1.5.3 { ifIndex, ifAdminStatus, ifOperStatus, ifDescr } 2.8
linkUp 1.3.6.1.6.3.1.1.5.4 { ifIndex, ifAdminStatus, ifOperStatus, ifDescr } 2.8
linkDown 1.3.6.1.6.3.1.1.5.3 { ifIndex, ifAdminStatus, ifOperStatus } 2.6 and 2.7
linkUp 1.3.6.1.6.3.1.1.5.4 { ifIndex, ifAdminStatus, ifOperStatus } 2.6 and 2.7

TB-MIB SNMP Trap/Notification

Trap Name Details OID OBJECTS RELEASE
tbNapAvailability The network access point has a new percentage of availability for calls
  1. For TDM networks (tbNapSignalingType=isdn(1), ss7(2), casr2(6)) this means there are a percentage of channels available for calls. ss7 includes sigtran signaling type.
  2. For SIP networks (tbNapSignalingType=sip(3)), this means the remote SIP device is answering or not SIP OPTIONS polling messages and calls can be or can`t be made to this network.
  3. When using H.248 (tbNapSignalingType=tdmMedia(5), voipMedia(4)) this means there are TDM channels or RTP ports available or not for calls.
