native vlan mismatch messages

Hello all

i know this is a very basic question, but I found out something...perhaps has
someone similar experience?
I have in the core a Cat6500 with CatOs 6.3.(1) and both port 8/5 and 8/6 are
configured with following:

set port channel off
set trunk mode off

But only one switch say to me native vlan mismatch. Both WS-C3548-XL have all
ports assigned to the default vlan 1 and the only difference is really only
the software! Have a look the both statements:

The first question is general: Is there a way to stop this native vlan
mismatch, without to disable cdp and not to change the vlan nummer on the
access-switch to the same as the port on the core switch?

The second question is to this problem? Does anybody share the same
experience with me somewhere else?

Oliver
