Hm... by default native VLAN should be VLAN1, and by default dot1q VLAN1
on routers at always placed at main interface - Gi0/1 at this case.

The problem (interface down , interface up) is also when I create any
subinterface, so:

conf t
  int giga0/1.400
  int giga0/1.401

will do 2 interface flaps on the switch. I'm not using native vlan...
and I want to leave native vlan on main interface.
