Fabio Semperboni Hi Gian Matteo Esposito, * The lines beginning L2 Switched ndicate the hardware-switching statistics. * About your second question, the answer is yes; the input/output drop counter will raise I forgot I had configured the PIX Outside interface for auto/auto because of some testing I was doing a few week ago (DOH!) I re-configured for 100/Full, and I'm working perfectly I'll find a higher-quality cable & see what happens.In summary, we're saying that CRC errors usually mean noise, or bad cabling, and framing-errors usually mean speed/duplex mis-match?

This problem occurs also when one site of a link is configured on auto-duplex and the other fixed (full-duplex).

A: Quick Answer There are numerous causes for Cyclic Redundancy Check (CRC) errors. Other input-related errors can also cause the input error count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum Bad hard drive sectors, scratched or dirty external media, loose wiring inside the computer and faulty external drives or buggy software are all potential causes.

Size/max/drops = the current number of frames in the queue / the max number of frames the queue can hold before it must start dropping frames / the actual number of In copper the signal travels by transferring state between electrons (electrons themselves are not traveling very much) and in fiber the signal travels by the photons reflecting off the walls of ARP type: ARPA, ARP Timeout 04:00:00 ARP type defines the encapsulation type of the interface; tipically, for ethernet interface is ARPA. Crc Errors Dsl Note: This counter is updated only when packets are process switched, not when packets are fast switched.

It is thus meant to ensure that the frame was not corrupted in transit. Input Errors On Interface Cisco Router Join us on Youtube!

The most common cause of late collisions is that your Ethernet cable segments are too long for the speed at which you are transmitting. Frame Errors cord cutting is not just for cable TV, but for power tools [HomeImprovement] by aurgathor338. For instance, any Ethernet packet that is less than 64 bytes is considered a runt. In TDM networks, there are many problems that cause CRC errors.

On a LAN, this usually indicates noise or transmission problems on the LAN interface or the LAN bus itself. No buffers: Number of received packets discarded because there was no buffer space in the main system. Now that have insight into what my interfaces are doing, I'm noticing some odd things.FA0/1 is hard-coded 100Mbit, Full-duplex.
