6.2.4 SNMP
♦
♦
♦
♦
To manage a large network of RFP offers, an SNMP agent is provided for each RFP.
The SNMP agent responds to SNMPv1, and SNMPv2c reads requests for the standard
MIB-II objects.
The agent supports both SNMPv1 and SNMPv2c alerts ('coldStart' , 'nsNotifyShutdown' ,
'authenticationFailure’ and 'nsNotifyRestart').
Decoding SNMP messages with your network management system or MIB browser
always requires the publicly available IETF MIB definitions (see reference documents at
the beginning of the document), which can be downloaded
