Traffic exceeds link capacity.
We have router which connected 45m hssi(A) with FR switch. That router contains two other interfaces, one is 45m hssi(B) and the other is 100m fddi (C). Because the most of the inbound traffic from (B) and (C) goes to (A) interface, the toal inbound traffic of (B) and (C) cannot exceed 45m. (Is it right ?) But the output rate of interface (A) exceeds 45m, -I can verify them in "sh int <int-name>"-, it increases upto 60~70 mbps. (Not really, but the statistic from CISCO commands.) When the phenomenen occurs, the total inbound traffic of (B) and (C) shows near 45 mbps (about 43.x mbps). My question is: Is it true that it indicates 60~70 mbps ? (Of cause, it has many output drops.) or Is it bug? The cpu load increases upto 99%, and it freezes router for short time -about 1~2 minute-. How to resolve this errors ? Our Router is: CISCO 7507 RSP2 IOS: 11.1.19 (CC) Enable CEF on (A): It is better than not using CEF. But the result doen't matter. (High CPU load, ..) Any Idea ? Thanks in advance --Jaeho Yang.

I recall this being a bug, I had a T1 that did 1.9 mb/s. I recall 11.2.x or 11.1.21 fixing it.

We're not talking an aggregate number here are we? Or is it that the average in (or out) over the previous 5 minutes was greater than the speed of the circuit? Brian On Wed, 23 Sep 1998 alex@nac.net wrote:

I would recommend upgrading to the latest version of CC IOS, as there are a number of bugs (including an OSPF one) in the version that you are running. 11.1.21CC is currently the latest, and has been working well for me for over two weeks. I seem to recall seeing a ddts related to it, but can't find the exact one... - Jared On Wed, Sep 23, 1998 at 12:51:37PM -0400, Brian Horvitz wrote:
