The NMS displays the alarm that the number of Pause frames received by an NE40E-X8A exceeds the specified threshold. This affects the existing services.
1. Run the display trap-buffer command on the NE40E-X8A to view alarm information.
2. Check that the device's interface status is normal.
3. Communicate with other parties. It is found that Pause frames are generated because the time parameter is carried. After a simple parsing of the received Pause frames, the device can determine the duration in which Pause frames are stopped from being sent. If the peer device experiences congestion, the local interface receives multiple consecutive Pause frames in most cases. The involved interface keeps sending Pause frames so long as the congestion status is not released. The NIC processing capability fails to support too many packets on the peer device. Therefore, the network congestion issue on the NE40E-X8A needs to be resolved.
