H.248 User's Manual
Each MIB is made up of a list of single MIB objects, each relating to a separate
attribute within a gauge or counter. All counters and gauges give the current time
value only.
•
acPerfMediaGateway - a generic-type of PM MIB that covers:
♦
♦
♦
•
acPerfMediaServices - Media services devices specific performance MIB.
2. New Format - includes new MIBs.
They all have an identical structure, which includes two major subtrees:
•
Configuration sub tree - allows configuration of general attributes of the MIB
and specific attributes of the monitored objects.
•
Data sub tree
The monitoring results are presented in tables. There are one or two indices in each
table. If there are two - the first is a sub-set in the table (Example: trunk number) and
the second (or the single where there is only one) index represents the interval
number (present - 0, previous - 1 and the one before - 2).
The MIBs are:
•
acPMMedia - for media (voice) related monitoring such as RTP and DSP.
•
acPMControl - for Control Protocol related monitoring such as connections,
commands.
•
acPMPSTN - for PSTN related monitoring such as channel use, trunk utilization.
•
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 goes back
under the threshold. The 'source' varbind in the trap indicates the object for which the
threshold is being crossed.
8.1.4.1 TrunkPack-VoP Series Supported MIBs
The TrunkPack-VoP Series contains an embedded SNMP Agent supporting the following
MIBs:
The 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 description.
RTP MIB - The RTP MIB is supported according to RFC 2959. It contains objects
relevant to the RTP streams generated and terminated by the board and to the RTCP
information related to these streams.
Note:
Version SN09
Control protocol
RTP stream
System packets statistics
The inverse tables are NOT supported.
