What Is CISCO-WAN-RTP-CONN-MIB?

CISCO-WAN-RTP-CONN-MIB is a Cisco-proprietary MIB for VISM media gateway cards, defining RTP (Real-time Transport Protocol) connections that carry voice bearer traffic between VISM endpoints in VoIP trunking applications. It exposes configuration objects for each RTP connection, including local/remote IP addressing and ports, codec type, packetization period, and voice-activity-detection (VAD) timers. Its role in monitoring is chiefly software/configuration-level: confirming a given RTP connection is correctly established end-to-end with the expected codec and QoS/ToS marking, plus (via its bearer stats group) tracking voice bearer traffic health rather than physical hardware status. It works alongside other Cisco WAN VISM MIBs (LAPD trunk, tone plan, announcement) that together implement VISM's VoIP trunking feature set. Locating vismRtpConnGrpTable and the bearer-stats objects under the CISCO-WAN-RTP-CONN-MIB OID tree is a typical first step before it is deployed on Cisco WAN switching platforms (e.g., MGX 8000 series) providing VoIP trunking for carrier telephony networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-WAN-RTP-CONN-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

What Can Be Monitored

RTP connection endpoint/IP/port mapping
codec type in use per connection
bearer ToS/QoS marking
RTP bearer statistics (loss/quality indicators)
voice-activity-detection timer settings

Supported Devices

Cisco WAN switching platforms with VISM cards, e.g. Cisco MGX 8000 series

Monitoring Examples

An administrator would poll vismRtpConnGrpTable/vismRtpConnGrpEntry, indexed by vismRtpConnNum and vismRtpEndptNum, to verify vismRtpRmtIp/vismRtpRmtPort match the intended remote VISM endpoint, and that vismRtpCodecType and vismRtpBearerTos are set as expected for the trunk's QoS policy. The vismRtpBearerStatsGrp objects would be checked for packet loss or jitter symptoms on an active call path. An unexpected vismRtpConnMode or a vismRtpVadTimer misconfiguration could explain choppy audio or unexpected silence suppression on a voice trunk.

IP vismRtpRmtIp	1.3.6.1.4.1.351.150.20.1.1.1.1.4	IpAddress	read-create	This object determines the remote VISM's IP address. For every RTP connection the remote port and remote IP pair needs to be unique.
RowStatus (1)
ROW vismRtpRowStatus	1.3.6.1.4.1.351.150.20.1.1.1.1.18	RowStatus	read-create	This object is used to create, modify or delete an entry. An entry can be created using the 'createAndGo' option. Before creating a RTP connection, the endpoint should have already been created. And the line signaling type should have been configured. For creating a RTP connection, vismRtpEndptNum, vismRtpLocPort, vismRtpRmtPort, vismRtpRmtIp and vismRtpCodecType need to be provided. For the other objects the default will be applied. The RowStatus would be set to 'active' by the agent while creating a RTP connection. While deleting a RTP connection the RowStaus will be set to 'destroy'. The RTP connection won't be deleted if there are still call going on the connection.
TruthValue (7)

In the case of switching application, the CAS bits are backhauled to the Call Agent through xGCP-CAS protocol. Note that if the line signaling type is CAS the default value is 'true(1)', else the default value is 'false(2)'.

T/F vismRtpICSEnable	1.3.6.1.4.1.351.150.20.1.1.1.1.16	TruthValue	read-create	This attribute is used to enable or disable the ICS(Idle Channel Suppression) for a connection. This can be specified while adding the connection and cannot be modified. When the ICS is enabled the DSP will look for the idle CAS (ABCD bits) pattern specified in ds0IdleCode in dsx0 MIB. If the idle pattern is present the DSP stops generating voice packets towards network side. By default the ds0IdleCode will be zero unless the user has configured it before adding the cid. If the ds0IdleCode is changed after the connection is added it will have no affect unless the card is reset.
T/F vismRtpTriRedundancy	1.3.6.1.4.1.351.150.20.1.1.1.1.12	TruthValue	read-create	This object tells whether the packets need to be sent in triplicates or not. If it is set to 'true(1)' the packets will be sent three times else will only be sent once (this is used for reliable links to save bandwidth). This object will override the card level object configuration vismVoIpTripleRedundancy(defined in CISCO-VISM-MODULE-MIB MIB). The default value is 'true(1)' if vismRtpDtmfTransport or vismRtpCasTransport is true, else 'false(2)'.
T/F vismRtpVad	1.3.6.1.4.1.351.150.20.1.1.1.1.15	TruthValue	read-create	This attribute defines whether the VAD has to be applied on this channel, upon detection of silence. For algorithms that do not have VAD standards, Cisco-proprietary VAD can be applied and the generic SID (Silence Information Descriptor) packet as specified in I.366.2 standards can be sent to the other end. When the codecType is clearChannel VAD has to be off.
