SNMP trap and syslog processing

When SNMP trap and syslog processing is enabled, Network Protocol Manager for OSPF obtains status for the OSPF-enabled devices by extracting the following information from the SNMP trap messages and syslog messages that are sent by the devices:

• Configuration status

• Change status

• Adjacency status

  SNMP traps and syslog messages are recommended but not required because Network Protocol Manager for OSPF polls the OSPF network for status information. However, if neither SNMP traps nor syslog messages are received by Network Protocol Manager for OSPF, immediate asynchronous notification of status change is not available; rather, the response time is determined by the length of the SNMP polling interval (240 seconds by default).

  By default, SNMP trap and syslog processing is disabled. The Network Protocol Manager Configuration Guide provides information about enabling trap and syslog processing and identifies the trap and syslog messages processed by Network Protocol Manager for OSPF.
