DEVM_1.3.6.1.4.1.2011.5.25.41.4.5 hwIfMonitorInputRateRising

Trap Buffer Description

Interface input flow bandwidth usage exceeded the trap threshold. (Interface=[IfIndex], BandWidthUsage=[hwIfMonitorInputRatePercentage], TrapThreshold=[hwIfMonitorInputRateThreshold], InterfaceName=[InterfaceName])

The trap was generated when the percentage of the rate of received traffic to the total bandwidth on an interface was greater than the threshold.

In VS mode, this trap is supported only by the admin VS.

Impact on the System

When the rate of traffic is close to 100% out of the total bandwidth, delay or packet loss will occur.

Possible Causes

The interface traffic statistics collection period can be configured. The default value is 300s. The average rate of the previous statistics collection period is calculated in every 1/6 of the statistics collection period and then divided by the interface bandwidth to obtain the interface bandwidth usage. If the interface bandwidth usage exceeds the interface alarm threshold, the interface rate threshold-crossing alarm is triggered.

Procedure

1. Run the display this interface command on the interface to check whether the traffic threshold is too low. The threshold range is specified by users according to actual services.

If so, go to Step 2.
If not, go to Step 3.

2. Run the trap-threshold input-rate bandwidth-in-use command to re-set the threshold and then check whether the alarm is cleared.

If so, go to Step 4.
If not, go to Step 3.

3. Collect alarm information and configuration information, and then contact technical support personnel.

4. End.
