Purpose

To describe the Simple Network Management Protocol (SNMP) Environmental Traps for AP Session Border Controllers

Details

The following objects fall into the SBC Environmental SNMP MIB.

- Changes in Voltage
- Changes in Temperature
- Changes in the status of the Fan Pack
- Changes in the status of the Power Supplies
- Changes in the I2C communication bus

To begin, the Environmental TRAPs can be enabled or disabled. In other words, if it's decided to enable SNMP TRAPS, it's possible to select whether or not the SBC should forward Environmental Alarms as SNMP TRAPS. This option is controlled in the sytem-config by either enabling or disabling the option "enable-snmp-monitor-traps". Enabling this option means the SBC will forward SNMP TRAPS for Environmental changes. The default is disabled. To enable, follow these steps.
(Please note that these changes will require a system reboot to take effect.)

Once the SBC's Environmental traps are enabled, there are two different formats to be aware of.

By default, the SBC will send an SNMP TRAP which will contain a unique SNMP OID for each event. Here are examples:

- Temperature Trap OID (apSysMgmtTempTrap)
o 1.3.6.1.4.1.9148.3.2.6.0.2
- Fan Pack Trap OID (apSysMgmtFanTrap)
o 1.3.6.1.4.1.9148.3.2.6.0.3
- Power Supplies Trap OID (apSysMgmtPowerTrap)
o 1.3.6.1.4.1.9148.3.2.6.0.1

However, the SBC can also be configured in such a way that every Environmental SNMP TRAP has the same TRAP OID (1.3.6.1.4.1.9148.3.3.4.0.2 - apEnvMonStatusChangeNotification). The common TRAP has the following structure.

1.3.6.1.4.1.9148.3.3.3.1 apEnvMonTrapInstance
<Value> which will be an OID related to Environmental object reporting the alarm, including location or instance>
1.3.6.1.4.1.9148.3.3.3.2 apEnvMonTrapPreviousState
<Value> an integer reflecting the previous state
1.3.6.1.4.1.9148.3.3.3.3 apEnvMonTrapCurrentState
<Value> an integer reflecting the current state

The Common OID requires correlation of the data within the Values to determine which Object is alarming and whether the Trap is an alarm or a clearing event.

The difference in the format of the Environmental TRAP is controlled in the sytem-config by either enabling or disabling the option "enable-env-monitor-traps". By default this option is disabled. Meaning, the SBC would send a SNMP TRAP with a unique TRAP OID. If enabled, the SBC will also send the "apEnvMonStatusChangeNotification" trap. To enable, follow these steps.
