Ser. Int. 5 min Input/Output Rate

Dear Net Pros,

On my serial interface of my AS 5350, I am having the following output as given below. The 5 minute input rate is half of the 5 minute output rate. Can someone suggest how I can fix this problem. I am currently also having access-lists configured in my gateway. Need some solution at the earliest possible.

The fact that the TX rate is twice that of the RX rate does not necessarily mean there is a problem, it just means you are sending more traffic than recieving.

I would be investigating why you are seeing output queue drops, even though the txload is low (11/255) -

Output queue 0/4096, 8898 drops; input queue 0/4096, 0 drops

Do you have LLQ set up and you are pushing too much traffic through the priority queue - if you exceed the strict priority setting this traffic is dropped.

Need configs and a better description of what is being passed through the router.

Here is the Gateway Config for you:
