Hi - I have several interfaces on a Cisco 2950T-24 switch showing an increasing "deferred" counter even though those ports are set to full-duplex. There are no other errors on the interfaces and traffic is light.
Can anyone tell me why the counter might be increasing and what symptoms I should expect. (I appear to be suffering packet loss but not 100% sure if I am on the right track). Thanks....
"The deferred counter counts the number of times the interface has tried to send a frame, but found the carrier busy at the first attempt (Carrier Sense). This does not constitute a problem, and is part of normal Ethernet operation." So if you don't see any other errors, then you might not having a problem. Are you sure you have a packet loss?
Thanks for the response - I actually did know what the definition of deferred was - I don't expect to see deferred counts increasing on a Fastethernet port set to full-duplex however.
Should I consider this normal on full-duplex FE ??
BTW - we were seeing packet loss across a C2950T-24 running 12.1(13)EA1 we have upgraded to 12.1(14) and the problem appears to have disappeared. Can't see any notices about this on the Cisco web site though....
