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.
