Interfac GigabitEthernet 2/9/1 :: Received Pause Frames Exceeded Threshold

At time something is not that big thing but live network is live which makes you so careful and conscious that you take care of each and every alarms of Router (NE40E). I saw the above alarms on my NE40E, when I try to troubleshoot so it was not that big problem. At time due to this may be some data services lost on that interface. You can get this due to some reasons which include “The receiving rate of pause frames exceeded the threshold” or it is receiving for continuous time.

Solution:

You just need to check the rate on the interface; if you see this alarm what you need is to reduce the traffic rate from neighbor node. In my case when I notice this so no high rate was noticed on the interface, it just appear for a while and then disappear.

I hope this will be informative for you.
