CHAPTER 9 Getting Started with SNMP
Mediant 800 SBC | SNMP Reference Guide
MEGACO and MGCP (amongst these are also the SIP relevant objects) and subtrees
that are specific to the different CPs.
●
acAnalog MIB: all objects in this MIB are related only to the configuration, status and
line testing or resetting of analog interfaces..
●
acPSTN MIB: configuration and status of trunk related objects only. Most of the MIB
objects are trunk specific. .
●
acSystem MIB: configuration and status of a wide range of general objects along with
chassis related objects and a variety of actions that can be instigated.
■
Performance monitoring MIBs – in the acPerformance subtree
. The different MIB
modules are grouped according to different virtual modules of the device. In general, the
division is as follows (a more detailed breakdown of the MIBs is discussed below):
●
acPMMedia, acPMControl, acPMAnalog, acPMPSTN, acPMSystem: module specific
parameters performance monitoring MIBs
●
acPMMediaServer MIB: performance monitoring specifically for MediaServer related
parameters (IVR, BCT, Conference and Trunk-Testing)
●
acPerfH323SIPGateway MIB: performance specific for SIP CP devices. This MIB’s
structure is unlike the other performance monitoring MIBs.
■
Proprietary Carrier Grade Alarm MIB – in the acFault subtree
:
●
acAlarm: a proprietary simplification of the standard notificationLogMIB and
alarmMIB (both are also supported)
The structure of the different MIBs is similar, depending on the subtree in which they reside.
The MIBs in the acBoardMibs subtree have a very similar structure (except the acBoard and
acGateway MIBs). Each MIB can be made up of four major subtrees:
■
Configuration subtree: mostly read-write objects, tables and scalars. The relevant
module’s configuration is done via these objects.
■
Status subtree: read-only objects, tables and scalars. Module status is collected by these
objects.
■
Action subtree: read-write objects that are used to instigate actions on the device (such as
reset, save configuration, and so on) and read-only objects used to receive the actions’
results.
■
Chassis subtree (in acSystem MIB only): read-write and read-only objects related to chassis
control and management (this includes, fan trays, power supply modules, PSTN IF
modules, etc’).
The acBoard MIB contains some deprecated objects and current proprietary trap definitions.
The acGateway MIB contains only the configuration subtree which in return is divided into
common, SIP and H323 subtrees. The H323 subtree is mostly deprecated or obsolete.
