Third-Party Performance Monitoring Measurements; Trunkpack-Vop Series Supported Mibs - Nortel Mediant TP-1610 SIP User Manual

11.4 Third-Party Performance Monitoring
Measurements
Performance measurements are available for a third-party performance monitoring system
through an SNMP interface. These measurements can be polled at scheduled intervals by an
external poller or utility in a media server or other off-device system.
The device provides two types of performance measurements:
Gauges: Gauges represent the current state of activities on the device. Gauges, unlike
1.
counters, can decrease in value, and like counters, can increase. The value of a gauge is the
current value or a snapshot of the current activity on the device.
Counters: Counters always increase in value and are cumulative. Counters, unlike gauges,
2.
never decrease in value unless the off-device system is reset. the counters are then zeroed.
Performance measurements are provided by three proprietary MIBs (acPerfMediaGateway,
acPerfMediaServices and acPerfH323SIPGateway). The first MIB is a generic-type of
performance measurements MIB available on all Mediant 2000 and related devices. The second
is specific to the media server, and the third is for H.323/SIP media gateways.
The generic performance measurements MIB covers:
•
Control protocol
•
RTP stream
•
System packets statistics
Performance
Proxy/Gatekeeper routing tables.

11.5 TrunkPack-VoP Series Supported MIBs

The Mediant 2000 contains an embedded SNMP Agent supporting the following MIBs:
•
Standard MIB (MIB-II) - 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's RFC 2959. It contains
objects relevant to the RTP streams generated and terminated by the device and to RTCP
information related to these streams.
•
Trunk MIB - The Trunk MIB contains objects relevant to E1/T1 Trunk interfaces.
•
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 proposed MIB also supported as part of our implementation of
carrier grade alarms. This MIB is still not standard and is therefore under the
audioCodes.acExperimental branch.
•
SNMP-TARGET-MIB - This MIB is partially supported (RFC 2273). It allows for the
configuration of trap destinations and trusted managers only.
•
SNMP Research International Enterprise MIBs - Mediant 2000 supports two SNMP
Research International MIBs: SR-COMMUNITY-MIB and TGT-ADDRESS-MASK-MIB.
These MIBs are used in the configuration of SNMPv2c community strings and trusted
managers.
In addition to the standard MIBs, the complete series contains several proprietary MIBs:
•
acBoard MIB - This proprietary MIB contains objects related to configuration of the device
and channels, as well as to run-time information. Through this MIB, users can set up the
device configuration parameters, reset the device, monitor the device's operational
robustness and Quality of Service during run-time, and receive traps.
