on Catalyst 2900 series switch, the port which is connecting switch to
the outside router suddenly started blinking orange. Everyone able to
get into the network but the connection became slow. Is it the problem
with the network traffic or more collisins or the cable problem.
What's the solution. How to check for more collisions?

Please somebody help.

Thanks
Suda

duplex mismatch?

do a sh int, look at number of collisions. Clear couters on interface then
do sh int again. See if number of collisions is going up.

there should be a mode button on the switch so that you can check 
different things, duplex/conn/..., so the blinking orange light 
indicates things that depand...

Hi,

I checked all those different modes. Everything looks good. And also
checked for no. of collisions by using show interface. It showed so
many no. of collisions (around 500,000).
So I believe, only solution for decreasing the no. of collisions is
increasing the bandwidth. Or something else can i do from my side??

Actually the switch is configured to have only two VLAN. That's it
nothing much complex configuration is used. So is it problem with
configuration?

Thanks
Suda

Hi,

I just now checked up  for the duplex mode. Actullay it is in half
duplex mode. So is it the real problem. Should i need to change it to
Full duplex mode.

As you said i did the clear counters on the interface and did the sh
int. It showed me 69 collisions immediatley after clearing the
counters. It is really  issue of collisions because of half duplex
mode?

Thanks
Suda
