acAlarm:
This is 3Com' 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 using
notificationLogMIB.notificationLogMIBObjects.nlmConfig.nlmConfigGlobalEntryLimit or
notificationLogMIB.notificationLogMIBObjects.nlmConfig.nlmConfigLogTable.nlm
ConfigLogEntry.nlmConfigLogEntryLimit.
The table size can be any value between 50 and 1000 (default is 500).
The following are special notes pertaining to MIBs:
•
A detailed explanation of each parameter can be viewed in an SNMP browser
in the “MIB Description” field.
•
Not all groups in the MIB are functional. See version release notes.
•
Certain parameters are non-functional. Their MIB status is marked “obsolete”.
•
When a parameter is set to a new value using SNMP, the change may affect
device functionality immediately or may require that the device be soft reset
for the change to take effect. This depends on the parameter type.
The current (updated) device configuration parameters are programmed into the
device provided that the user does not load an
ini
file to the device after reset.
Loading an
ini
file after reset overrides the updated parameters.
Traps
Full proprietary trap definitions and trap Varbinds are found in the acBoard MIB and acAlarm
MIB.
Table 73
lists the supported proprietary traps. For detailed information on these traps,
see
Appendix I: SNMP Traps
.
All traps are sent from the SNMP port (default 161). This is part of the NAT
traversal solution.
Full proprietary trap definitions and trap Varbinds are found in the acBoard MIB and acAlarm
MIB.
