input errors keep increasing

Hi there,

I've configured my router c7200 and run VLAN 802.1q. At the main trunk, I noticed on my switch Cat 2924 XL, from the sh interface output, the input error keep increasing tremendously. Below is the output:

cat2924#sh int fa0/1

My question, what makes the input errors keep on increasing? Is it indicate a problem that need to be resolve?

Need your expert advise.

Thank you very much.

Re: input errors keep increasing

usually:duplex mismatch, bad cables or NIC problems.

Re: input errors keep increasing

Vlad,

Thanks for the suggestion. I will try have a look and troubleshoot to norrow down the problem. BTW, for duplex mismatch, I sure that from the sh interface command full-duplex :) perhaps bad cables or port fast-interface NIC problems?

thanks.

Re: input errors keep increasing

Usually wiring problems specially it looks like one side is clean and the other is not . Also i have never seen a hold queue command on a layer 2 switch I think I would get rid of those 2 commands off that interface.

Re: input errors keep increasing

Hi Glen,

I think on the Cat2924 right, the wiring problems seems not clean? Not the Router right? Regarding the hold-queue not sure, but if I remove the command no service impact perhaps? Maybe used to buffer the packet in queue ...

thanks.
