Please post
Rack1R2#sh run interface fa0/0.126
Also, It would be good to sniff what the switch is sending out, as BSD-BOX
might be a culprit as well. Are you sure your BSD-BOX supports it? When you
install VLANs on BSD, there could be a problem with sniffing VLANs.
Try insalling routers (or any device) instead of it, or sniff like that:
on switch2
mon sess 1 source int gi 1/0/23 both
mon sess 1 desct int gi x/x/x encap replicate
