bandwidth usage 100%

Unanswered Question
Mar 24th, 2008

We are using cisco 1811 connect to ADSL2+ service in Australia. ADSL2 speed should be up to 24Mb download. When I check the monitor of interface, the usage are steadily at 100%. But check the actually download usage from the isp, the download is fairly low. When I show int dialer0, the output of 5 mins average is 599000bit/sec.

Also in traffic monitor session, more than 50% input packets is DNS.

So what makes the bandwidth usage so high? Can DNS chew up all the bandwidth?Is there a way I can check?

I have this problem too.

can you manually check the bandwidth parameter defined under the interface ?

most of the times you end up seeing the wrong counter values being displayed because of the incorrect bandwidth value set or the default value comes up with each interfaces.
