Configuring the Trap Function
Context
A device generates traps no matter whether an NQA test succeeds or fails. NQA supports three types of traps as defined in DISMAN-PING-MIB. NQA also supports the sending of traps to the NMS when the one-way or two-way transmission delay exceeds the threshold.
- For all test instances, if the two-way transmission delay exceeds the threshold and the trap function is enabled, traps are sent to the NMS with the specified IP address.
- During a jitter test, if the one-way delay from the source to the destination or from the destination to the source exceeds the threshold and the trap function is enabled, the NQA client sends a trap message to the specified NMS IP address.
Traps carry the following information: destination IP addresses, operating status, destination IP address of the test packet, minimum RTT, maximum RTT, total RTT, number of sent probe packets, number of received packets, RTT square sum, and time of the latest successful probe.
Configuration Procedure
The following optional configuration tasks are performed on the NQA client.
These configurations take effect only after the NQA alarm function is enabled.
- Enabling the NQA Alarm Function
- Configuring the NQA Client to Send Traps When a Test Fails
- Configuring the NQA Client to Send Traps When a Probe Fails
- Configuring the NQA Client to Send Traps After a Probe Succeeds
- Configuring the NQA Client to Send Traps When the Transmission Delay Exceeds the Threshold
- Verifying the NQA Trap Function Configuration
