Hello.
Can you provide us with your real configurations? I see by your port descriptions that they are not accurate.
From both sites provide
show run
show int trunk
show cdp nei det
Thanks

Hi,
Yes the config is tailred with other IP.
one Site.B If I remove "switchport mode access" from internface fa 0/5 then i dont get this error.
If I change the VLAN-ID on Site.B then its to ok.
I am trying to understand why with same vlan.id I get this error

If running CDP you can do a show CDP neighbors and you can see what the native VLAN that is being received. This might help you figure out which side is wrong.
Workaround would be to hard configure the native VLAN.
