Hi all,
Today's fun involved setting up my Windows box to bridge two Ethernets
together. Attached to these two interfaces are C3560-8PCs. I am capturing
DTP and STP traffic between the switches using WireShark. When I do ISL
trunking, this works great, as there is no native VLAN. When I do dot1q, I
get an unexpected result. Basically, the Windows box is participating in
STP and is winning in the native VLAN, as it doesn't do extended system ID
(thus, priority is default of 32768 vs. 32769 on VLAN1)! I'd like to either
disable STP on the Windows box altogether or, at the very least, raise the
priority such that it doesn't become root. Yes, of course I can just lower
the priority on all of my switches instead, which is Plan B. But I'm pretty
sure the problem can be solved on the Windows box, and I know some of you
around here are pretty Microsoft smart, whereas I am not.
Regards,
Scott
