SIP User's Manual 14. SNMP-Based Management
Version 5.0 309 December 2006
The MIBs include:
• acPMMedia: for media (voice) related monitoring (e.g., RTP, DSP’s).
• acPMControl: for Control-Protocol related monitoring (e.g., connections,
commands).
• acPMAnalog: for analog channels in offhook state.
• acPMSystem: for general (system related) monitoring.
The log trap, acPerformanceMonitoringThresholdCrossing (non-alarm), is sent out every
time the threshold of a Performance Monitored object is crossed. The severity field is
'indeterminate' when the crossing is above the threshold and 'cleared' when it falls bellow
the threshold. The 'source' varbind in the trap indicates the object for which the threshold is
being crossed.
14.5 Total Counters
The counter’s attribute 'total' accumulates counter values since the board’s most recent
restart. The user can reset the total’s value by setting the Reset-Total object.
Each MIB module has its own Reset Total object, as follows:
 PM-Analog: acPMAnalogConfigurationResetTotalCounters
 PM-Control: acPMControlConfigurationResetTotalCounters
 PM-Media: acPMMediaConfigurationResetTotalCounters
 PM-PSTN: acPMPSTNConfigurationResetTotalCounters
 PM-System: acPMSystemConfigurationResetTotalCounters
14.6 Supported MIBs
The MediaPack contains an embedded SNMP Agent supporting the following MIBs:
 Standard MIB (MIB-2): The various SNMP values in the standard MIB are defined in
RFC 1213. The standard MIB includes various objects to measure and monitor IP
activity, TCP activity, UDP activity, IP routes, TCP connections, interfaces and general
system indicators.
 RTP MIB: The RTP MIB is supported in conformance with the IETF RFC 2959. It
contains objects relevant to the RTP streams generated and terminated by the device
and to RTCP information related to these streams.
 NOTIFICATION-LOG-MIB: This standard MIB (RFC 3014 -
iso.org.dod.internet.mgmt.mib-2) is supported as part of our implementation of carrier
grade alarms.
 ALARM-MIB: This is an IETF MIB (RFC 3877) also supported as part of our
implementation of carrier grade alarms. This MIB is a new standard and is therefore
under the audioCodes.acExperimental branch.
 SNMP-TARGET-MIB: According to RFC 2273. It allows for the configuration of trap
destinations and trusted managers.
 SNMP MIB: This MIB (RFC 3418) allows support of the coldStart and
authenticationFailure traps.
 SNMP Framework MIB: (RFC 3411).
 SNMP Usm MIB: this MIB (RFC 3414) implements the user-based Security Model.
 SNMP Vacm MIB: This MIB (RFC 3415) implements the view-based Access Control
Model.
 SNMP Community MIB: This MIB (RFC 3584). implements community string
management.
 ipForward MIB: (RFC 2096) fully supported
