TelcoBridges offers basic support  for SNMP versions 1, 2, and 3. 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 ([[Media:TB-MIB-2011.txt|'''TB-MIB''']]).

=== SNMP IF-MIB ifTable interface type ===
 +
The following table provides the interfaces type supported by TelcoBridges (IF-MIB ifTable described in [https://tools.ietf.org/html/rfc1573 RFC1573]) with their corresponding description. The ifType are described in Internet Assigned Number Authority (IANA) in [http://www.iana.org/assignments/ianaiftype-mib IANAifType-MIB]

=== 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 [[SNMP#Configuration|SNMP configuration]].

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 Tctrl version history). 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).

Supported SNMP MIB modules

  1. RFC 1213 MIB II (RFC1213-MIB)
    • All tables of the RFC1213-MIB are supported, with the exception of:
      • ipRouteTable
      • EGP group

  2. RFC 1573 Evolution of Interfaces Group of MIB-II (IF-MIB)
    • The following tables are supported:
      • ifTable

  4. RFC 2496 - Definitions of Managed Object for the DS3/E3 Interface Type (DS3-MIB)
    • The following tables of the DS3-MIB are supported:
      • Dsx3ConfigTable
      • Dsx3CurrentTable
      • Dsx3IntervalTable

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 SNMP 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 CONSIDERED AS AN ALARM 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.

Note

The ifIndex is a random value that can change after configuring the system, or adding new elements. This should not be relied on as a reference value. Please use the ifDescr instead.

SNMP SET

The SNMP SET command is not supported by TelcoBridges products. However, a RESTful API can be used to change the configuration remotely.


Configuration

The below procedures should be used to support SNMP v1 ONLY for Toolpack systems previous to 2.5.80:
