Auditing
Auditing includes regular auditing and data auditing. With regular auditing, you
can use the SNMP agent to poll the value of the following MIB variables:
• sysUpTime (1.3.6.1.4.1.562.29.1.1.3)
• currentTxNotificationSequenceNum (1.3.6.1.4.1.562.29.1.6.1)
Active alarm status
A management application can determine the latest alarm for a particular
network element. When the network element instance restarts, the value is
reset to zero.
SNMP management
The MAS platform provides SNMP management. SNMP management
supports outgoing traps for logs and alarms to remote SNMP-based Network
Management Stations (NMS). In addition, NMS can query alarm table and
audit services. Use the Nortel MAS Console to activate the Windows SNMP
service and configure system parameters.
Traps
Traps use the Nortel Reliable MIB format to support active and cleared alarm
notifications as well as informational log messages. To enable or disable
alarm-related traps and information log traps, use the Nortel MAS Console.
MAS SNMP agent
The MAS SNMP agent supports queries on the ActiveAlarm table and audits
for resynchronization with the management server. These queries can be in
the form of Get requests on specific fields or GetNext requests for table
traversal.
SNMPv1/v2
SNMPv1/v2 uses community names to authenticate messages. The
community name is like a password shared by the SNMP NMS and the MAS
SNMP agent. The community name must be the same value on both the NMS
and the MAS SNMP agent.
Supported MIBs
Nortel supports the following MIBs. You must load MIBs in the following order:
1 nortel.mib
2 nortelGenericMIBs-smi2.mib
3 nortelNMItextConv-smi2.mib
4 nortelNMIconfigMgmt-smi2.mib
5 nortelNMIconformance-smi2.mib
