Oracle SBC Security Guide
Appendix H: Simple Network Management Protocol (SNMP)
SNMP OIDs
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 (as of S-CX6.3 and above) for GET and SET requests. Oracle release specific SNMP MIBs
can be found on docs.oracle.com for the release in use.
System Management Statistics
Below is a recommended list of SNMP OIDs to GET every 5 minutes from the Oracle System
Management MIB (ap-smgmt.mib). These will provide useful data on overall system performance and
security issues.
