Description: This persistent variable controls the generation of SNMP traps by the Agent within the NMU of the radio.

'disabled' forces the Agent to not generate any SNMP traps.

'unLimited' allows the Agent to send any and all traps, without any controls to limit the flow. (Other filters may cause traps not to be sent.) 'unLimited' is the default value.

'feedbackPinLimited' causes the Agent to limit the number of traps that can be sent in a specified time period. If the Agent needs to send more traps than allowed, then it sends a final Trap (nmu.trap.nmTrapsDisabled) indicating that the limit has been reached. The Agent then disables its ability to send traps. This method is described in RFC 1224. Setting this MIB to 'feedbackPinLimited' automatically causes the variable 'trapFlow' to be forced to 'open'. For details see the MIB descriptions for the two other controlling variables 'trapWindowPeriod' and 'trapMaxPerWindow'.

The Agent determines if a trap can be sent by examining several controls (or filters), all of which enable the sending of the trap. These are described in their order of checking below:

One, the MIB variable that enables that specific trap to be sent is enabled. (Each trap can be selectively enabled or disabled.) If a trap is not sent due to this filter, then 'trapFilteredSpecific' is incremented.

Two, the MIB 'trapControl', is set to 'unLimited'; or, it is set to 'feedbackPinLimited' and 'trapFlow' is set to 'open'. If a trap is not sent due to this filter, then 'trapFilteredControl' is incremented.

Three, one or more trap managers must be defined in the table 'trapMgrTable' with a valid IP address in 'trapMgrTable.trapMgrAddress', and their control variable 'trapMgrTable.trapMgrControl' must be configured to 1) 'both' or 'standard' and the trap is a standard trap; or 2) 'enterprise' or 'both', and the trap is an enterprise trap. If a trap is not sent due to this filter, then 'trapFilteredManager' is incremented.

Four, the trap has no associated severity level, or the severity level of the trap is equal or higher than the value specified by the severity filter 'trapSeverityFilter'. If a trap is not sent due to this filter, then 'trapFilterdSeverity' is incremented.
