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.

Main functions are as follows:

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.

Common SNMP Agent Subagent (OAGS)

OAGS plays the SNMP subagent role to support the standard SNMP (SNMPv2c/SNMPv3).

Also, through master agent (SNMPD) OAGS plays an interface role for the upper

management system for the command inquiry and change of ACR to be operated through

the get/get-next/get-bulk/set/trap command defined by SNMP.

Main functions are as follows:

y Providing private MIB

− Provide private MIB to the management system.

− Generate the message data file necessary for the interface function between OAM

blocks.

y SNMP command processing

Process the command received from the management system and transmit the

corresponding result via the SNMPD.

y Notification function

Send the SNMP trap to master agent (SNMPD) whenever there are needs to inform the

change or the alarm of the SPI-2L10 data to the upper management system.
