The above is the port status of a problem port , we've connect and Access point to this port . It shows 25650input errors and 8559 CRC error, is it a cabling problem or the port is faulty , what does it means?

Hi Raymond,

Normally this points to layer 1 issues please check the following:

1. Check the speed/duplex both the ends

2. Check the cable / fiber / trasnceiver
3. Check by changing the speed and duplexto half or Auto
4. Chek if the grounding is proper

5. Check patch panel (if there is one)

Also this is a link for a cable test check it out:

Hope this helps.

Hi,

Check with cable and if possible run tdr on that port.

CRC is definitely a physical layer issue.

Whats the distance b/w these two endpoints.
