3.3.3.1 SNMP Daemon (SNMPD)

SNMPD plays the SNMP agent role to support the standard SNMP (SNMPv2c/SNMPv3)

and an interface role for the upper management system (WSM) and interworks with

internal subagent. While receiving requests on the standard MIB object from WSM are

processed by SNMPD itself, it transmits requests on the private MIB object to subagent in

order to be handled properly.

SNMPD Main Functions

y Standard MIB processing

If the request for the MIB-II object is received, the SNMPD processes it directly and

transmits the response.

y Private MIB processing

If the request for the Private MIB object is received, it is not processed directly by the

SNMPD, but it is transmitted to the corresponding internal subagent, and then the

response is transmitted from the subagent and it is transmitted to the manager.

SNMPD Implementation

SNMPD is implemented on the MMA-G as shown below.
