In our DC we have connection between TWO devices via 10Gbase-SR-S module. Reissue the command to clear the interface statistics again. we see input errors on interface Gi0/1 on cisco 1941/K9. If runts and Cyclic Redundancy Check (CRC) errors are incrementing in the show interface command output, or Frame Check Sequence (FCS) errors and runts are incrementing in the show port command output, check the port speed and duplex settings. Other input-related errors can also cause the input error count to be increased, and The "input errors" counter will increment whenever the interface receives a frame with any sort of input error, which includes CRC among other types of errors. The picture attached is an example sent to another network and another IP LAN interface. Solved: In viewing logs on each of my Catalyst 3500XL Switches I see several Input errors, collisions, 23467079 packets input, 29007154284 bytes, 0 no buffer. " interface to report incrementing input errors and gives possible workarounds to prevent these errors, while indicating the release in which the issue is resolved. Description: how interfaces show interfaces counters errors. I have 2 questions: 1. What I actualy need is a method to show all interfaces in a specific vlan containing input errors in a campus network of about 40 Cat.
