Re: Simple Spanning Tree Question

Usually It shows the mac of the switch with .... 0019.307b.0000 instead of
0019.307b.0f80 ( which is i believe the mac of the port )

I think if it shows in the sh span brief , it will show also in sh mac-ad
if it is shown as root, it will be shown also in the span tree of other
switch

cheers,
