Hi,

In this simple example, where I configured a mismatch native vlan :

sw 1 : dot1Q, native vlan = 1
sw 2 : dot1Q, native vlan = 2

SH IP INT BRIEF shows that :
fa0/x stays up/up
vlan1 goes up/down

What is the logic behind this behavior ?
I would have expected the fa0/x to go up/down !

Thanks,
Navid
