G SNMP Monitoring

Simple Network Management Protocol (SNMP) polling (GET and SET) requests are used to retrieve operational data and modify configuration are supported by SBC. The SBC supports SNMPv1 and SNMPv2c for GET and SET requests. Oracle recommends using SNMPv3. Oracle release-specific SNMP MIBs can be found on docs.oracle.com for the release in use.

Below is a recommended list of SNMP OIDs to retrieve regularly from the Oracle System Management MIB (ap-smgmt.mib). Use the snmpgetnext, snmpgetbulk, snmpwalk, or snmpwalkbulk commands. These will provide useful data on overall system performance and security issues.
