Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-VOICE-LMR-MIB?

CISCO-VOICE-LMR-MIB supports Cisco's Land Mobile Radio (LMR) gateway integration feature, which lets IP telephony/voice gateways interoperate with two-way radio systems by injecting configurable static tones -- wake-up, guard/idle, and pause tones -- before and during voice playout to keep the radio channel active and correctly selected. It exposes configuration objects defining tone classes, digital filter settings, guard tone frequency/amplitude, and idle-tone behavior, along with per-class signal tone sequence tables. This MIB is almost entirely configuration-oriented rather than exposing hardware/performance counters, so its monitoring value is limited to verifying tone-class settings are correctly provisioned for a given radio interoperability deployment (e.g., confirming guard tone frequency matches what the radio system expects). It depends on the voice gateway's underlying dial-peer/voice-port configuration framework on which LMR tone classes are applied. It is deployed on Cisco voice gateways used to bridge IP/PSTN calls into Land Mobile Radio (public safety/two-way radio) systems. Network engineers evaluating or troubleshooting this functionality can download the CISCO-VOICE-LMR-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-VOICE-LMR-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.

Monitoring Examples

cvlClassTable/cvlClassEntry exposes cvlClassName alongside cvlGuardToneFreq and cvlGuardToneAmp, letting an admin verify the configured guard tone matches the frequency/amplitude expected by the connected radio system. cvlSignalToneTable/cvlSignalToneEntry defines the tone-and-pause sequence used to wake and select a radio channel, so an operator can confirm the sequence is correctly provisioned; this MIB is configuration-focused with essentially no runtime performance counters to monitor for anomalies.

What Can Be Monitored

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoVoiceLmrMIB	1.3.6.1.4.1.9.9.510			This MIB module provides management of voice tone signal as static injected tone for Land Mobile Radio The tone signal includes tone, pause, guard/idle tone. User can configure a sequence of tone and pause to be played out before any voice sample is played out. These tones are used to wake up the radio and select the radio channel. During the voice playout, a configured guard tone will be mixed with the voice to keep the radio active. For some radio systems, there is no need for the guard tone, but a configured idle tone is needed to inform the radio that the channel is idle. It is possible that the radio system will generate guard/idle tone. In that case, the IOS can instruct the DSP to filter out the radio generated guard/idle tone by enabling digital filter. Digital filter is able to filter out either 1950HZ or 2175HZ tone.
cvlClassEntry	1.3.6.1.4.1.9.9.510.1.1.1.1		not-accessible	A concept row in cvlClassTable. It has class name, tone frequency, tone amplitude, guard/idle tone indicator and digital filter information.
U32 cvlClassIndex	1.3.6.1.4.1.9.9.510.1.1.1.1.1	Unsigned32	not-accessible	An arbitrary integer which increases monotonically to index the cvlClassTable.
STR cvlClassName	1.3.6.1.4.1.9.9.510.1.1.1.1.2	SnmpAdminString	read-only	The object reflects the voice class name.
cvlClassTable	1.3.6.1.4.1.9.9.510.1.1.1		not-accessible	The table contains the LMR guard/idle tone frequency and amplitude. It also specifies what frequency will be filtered out from radio voice input by dsp digital filter.
INT cvlDigitalFilter	1.3.6.1.4.1.9.9.510.1.1.1.1.3	INTEGER	read-only	This object reflects which tone frequency should be filtered out from radio input.
VOI cvlGuardToneAmp	1.3.6.1.4.1.9.9.510.1.1.1.1.5	VoiceAmplitude	read-only	This object reflects the guard/idle tone amplitude in dbm.
VOI cvlGuardToneFreq	1.3.6.1.4.1.9.9.510.1.1.1.1.4	VoiceFrequency	read-only	This object reflects the guard/idle tone frequency between 1-4000 HZ. If there is no guard/idle tone configured for this voice class, cvlGuardToneFreq has value 0.
T/F cvlIdleToneFlag	1.3.6.1.4.1.9.9.510.1.1.1.1.6	TruthValue	read-only	This object reflects this voice class has guard/idle tone configured. true means guard tone and false means idle tone.
