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,
1. Please check the port setting on other side (Measn on AP).Both the end of the interfaces should have same speed and duplex settings.
2. Check the phyisical cabling
3. If switch supports TDR, use the "test cable-diagnostics tdr" command.
4. use this command to clear the error: clear counters FastEthernet0/29

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:
