Threshold Example

Suppose you want SNMP to warn you if the number of high-priority (Priority

Level 1) packets queued for transmission is approaching the maximum number

supported by an interface. This maximum value is specified by the

wfCctOptsCngcCfgQp1Threshold MIB object. Using the threshold parameters,

you set a threshold for wfCctOptsCngcCfgQp1Threshold equal to 205.

You also set the polling interval to 20 seconds to indicate that, every 20 seconds,

the agent should check variables for which you have configured thresholds. You

set the threshold action to Greaterthan and set the threshold levels and severity of

events to the values shown in Table 2-2

When you add this threshold to the MIB, the agent polls the variable

wfCctOptsCngcCfgQp1Threshold every 20 seconds and responds as follows:

• If its value is greater than 102, but less than or equal to 153, the manager logs

an informational event indicating that the queue depth exceeded the low

threshold.

• If its value is greater than 153 but less than or equal to 205, the manager logs

an informational event indicating that the queue depth exceeded the medium

threshold.

• If its value is greater than 205, the manager logs a warning event indicating

that the queue depth exceeded the high threshold.

Event Message Format

By default, the threshold event messages include the MIB object identifier (OID)

of the variable that exceeded the threshold, the value of the variable, and the

threshold level exceeded.
