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?
