A 2900XL was installed. However on observing the utilisation we see that upto 14th led is glowing green.Next 4 were in amber color leds.What could this indicate?

Re: 2900XL

Check your users manual, it says what each mode indicates, and how to read it. The Utilization mode is a "meter" indicating the real time utilization of the switch. Think of it as a one-line bar graph.

Re: 2900XL

After checking the manual to figure out the % utilization, you can check the following:

In EXEC mode, use Show Proc CPU command to take a look at the realtime CPU utilization. On the display, the CPU% of 30 - 50 is normal on a switch. If the number is very high and stays high (say 80 - 95%), you should check the detailed process CPU% to see who is on top of the list.

Also, you can check the statistics for individual port to see if a NIC is sending garbage at high rate (bad NIC).

Hope this helps.

Re: 2900XL

The amber leds indicate maximum Utilization reached since last boot. Sometimes, when STP resolves a loop, the utilization goes up for an instant, and thet leaves the high amber marks as a scar in your switch.

I agree with someone else.. check actual utilization with CLI commands.
