Hi,
i have a cisco 2911 router with 100M ethernet link.
The bandwidth is below 200/255, even than the output drops are increasing.
The CPU process is normal. I cannot find out a cause for the same.
Can someone help.

Post the complete output to the command "sh interface <PORT>".

Total output drops: 12467088
This means that packets meant to go through the WAN link is being dropped by the router.
