As noted above, five new MIBs cover the device's general parameters. Each contains a
Configuration subtree for configuring related parameters. In some, there also are Status and
Action subtrees.
The 5 MIBs are:
AC-ANALOG-MIB
AC-CONTROL-MIB
AC-MEDIA-MIB
AC-PSTN-MIB
AC-SYSTEM-MIB
Other proprietary MIBs are:
acGateway MIB - This proprietary MIB contains objects related to configuration of the
device when applied as a SIP or H.323 media gateway only. This MIB complements the
other proprietary MIBs.
The acGateway MIB has the following groups:
Common
SIP - for SIP parameters only
H.323 - for H.323 parameters only
acAtm - This proprietary MIB contains objects related to configuration and status of the
device when applied as an ATM media gateway only. This MIB complements the other
proprietary MIBs.
The acAtm MIB has the following groups:
acAtmConfiguration - for configuring ATM related parameters
acAtmStatus - for the status of ATM connections
acAlarm - This is 3Com's proprietary carrier-grade alarm MIB. It is a simpler
implementation of the notificationLogMIB and the IETF suggested alarmMIB (both also
supported in all 3Com devices).
The acAlarm MIB has the following groups:
ActiveAlarm - straightforward (single-indexed) table, listing all currently active alarms,
together with their bindings (the alarm bindings are defined in acAlarm. acAlarmVarbinds
and also in acBoard.acTrap. acBoardTrapDefinitions.
oid_1_3_6_1_4_1_5003_9_10_1_21_2_0).
acAlarmHistory - straightforward (single-indexed) table, listing all recently raised alarms
together with their bindings (the alarm bindings are defined in acAlarm. acAlarmVarbinds
and also in acBoard.acTrap. acBoardTrapDefinitions.
oid_1_3_6_1_4_1_5003_9_10_1_21_2_0).
The table size can be altered via
notificationLogMIB.notificationLogMIBObjects.nlmConfig.nlmConfigGlobalEntryLimit or
notificationLogMIB.notificationLogMIBObjects.nlmConfig.nlmConfigLogTable.nlm
ConfigLogEntry.nlmConfigLogEntryLimit.
The table size can be any value between 50 to 1000 and is 500 by default.
