Oracle SBC Security Guide

 enable-snmp-syslog-notify – enable syslog conversion to SNMP

 enable-snmp-monitor-traps – enable unique trap-IDs for each syslog event

The SBC setting to enable environmental monitors may seem advantageous, but is not recommended, and

should remain at the default – disabled. The same traps are already sent as part of the ap-smgmt MIB.

 enable-env-monitor-traps – sends traps for environmental issues like temperature, voltage, fan

speeds, etc.

SNMP Traps

The following are a selection of the most common or important traps sent by the SD. The full list of traps

can be found in the MIB Reference Guide and MIB files for the release implemented:

 apSwCfgActivateNotification (1.3.6.1.4.1.9148.3.4.3.0.1)

o Generated when the activate-config command is issued at ACLI and configuration has

been changed at run time. This trap may be seen often but is only informational and

doesn’t necessarily mean there is an issue (unless the config changes are service affecting

or the change was not authorized).

 apEnvMonStatusChangeNotification (1.3.6.1.4.1.9148.3.3.2.1.0)

o Generated when the environmental state of the SBC changes. Environment traps include

main board PROM temperature, CPU voltage, state of power supplies, fan speeds, etc. To

receive this trap, the system-config parameter enable-env-monitor-traps needs to be

enabled. An example of this trap for voltage state change is found in [4].

 apSysMgmtGroupTrap (1.3.6.1.4.1.9148.3.2.3.0.1)

o Generated when an SBC resource threshold or health score is exceeded. For example, if

NAT table usage, ARP table usage, memory usage, or CPU usage reaches 90% or

greater. Also, If the health score for an HA pair falls below 60.

 apSysMgmtExpDOSTrap (1.3.6.1.4.1.9148.3.2.8.0.2)

o Generated when an endpoint exceeds configured thresholds and is denied access by the

SD.

 apSysMgmtInetAddrWithReasonDOSTrap (1.3.6.1.4.1.9148.3.2.8.0.4)

o This trap is generated when the IDS Reporting Feature Group license (available in S-

CX6.3 and above) is installed. This trap is generated when thresholds are exceeded, and

contains further data on the end-point and reason why the trap was generated. When IDS

Reporting is installed the apSysMgmtExpDOSTrap is disabled.

 apSysMgmtInetAddrTrustedToUntrustedDOSTrap (1.3.6.1.4.1.9148.3.2.8.0.5.)

o This trap is available in S-C[xz]6.4.0 and above. It will be generated when the number of

rejected messages exceeds the configured threshold and the endpoint is demoted from the

trusted to untrusted list. The trap-on-demote-to-untrusted setting under media-manager

must be enabled for this trap to be sent.

 apSysMgmtRejectedMesagesThresholdExeededTrap (.1.3.6.1.4.1.9148.3.2.6.0.57)

o This trap is available in S-C[xz]6.4.0 and above. A trap will be generated when the

number of rejected messages exceed the configured threshold and the endpoint is put into

the untrusted queue.

 apSysMgmtSipRejectionTrap (.1.3.6.1.4.1.9148.3.2.10.0.1)

o Generated when a SIP INVITE or REGISTRATION request fails

 apSysMgmtPowerTrap (1.3.6.1.4.1.9148.3.2.6.0.1)

o Generated if a power supply is powered down, powered up, inserted (present) or removed

(not present).

 apSysMgmtTempTrap (1.3.6.1.4.1.9148.3.2.6.0.2)
