Problem Interface

[peguayapero]

I have the following message:

reliability 255/255, txload 248/255, rxload 40/255

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 258145

That signifies, I have time out when I do ping, that I can do?

The complete exit of sh interface s0/0, is the following one:

Hi,

Output drops are a result of your traffic exceeding the capacity of your link and from what I can see, you are driving the interfaces to capacity - your txload is 248/255 - very high indeed.

The only solution to your problem is to add more bandwidth.

Hope that helps - pls rate the post if it does.

How know which are the normal values of txload and rxload?

[pkhatri]

There is no such thing as a 'normal' value. However, if you start approaching 255/255, you know that you are pushing the interface hard and it's time to get a bit more bandwidth. The load is the proportion of actual traffic to interface bandwidth.

Hope that helps - pls rate the post if it does.

On the other hand in the same one router in the same instant, in another interface, I had the following exit:

The values, txload they are normal?, I have Total output drops, Why?, bandwidth problem?
