Cisco Catalyst WS-C3560-48TS and DLINK 3120 interface errors

sistemaspcsnet
Level 1
Level 1

Hello, 

We are getting  a lot of FCS-Err in one FC- GIgabit trunking  interface between  Cisco Catalyst WS-C3560-48TS running IOS   Version 12.2(25)SEE3 and DLINK 3120 Firmware 4.00.015.

Our config in the cisco is the following:

interface GigabitEthernet0/1
 description SWITCH-Dlink01
 switchport trunk encapsulation dot1q
 switchport mode trunk
 macro description cisco-switch
 spanning-tree link-type point-to-point
!

-----

We have tried without "macro description cisco-switch" and "spanning-tree link-type point-to-point" too and the problem persist.

 

If we run "sh interfaces counters errors"

Port        Align-Err    FCS-Err   Xmit-Err    Rcv-Err UnderSize

Gi0/1               0      11423          0      11423  12516029

The errors counters in the DLINK are growing very fast too.

Usually these errors are related with hardware or cable problems, we have changed the cable, the SFP and the port, but the problem is still there.

We have activated the debug for the interface and syslog, but we aren't getting any error.


Do you have any idea about this issue or how to troubleshoot it?

Hi,

Try to hard set the ports on both sides to Gig/full duplex and test again.

Hi Reza,

Speed and duplex are fixed in both switches.
