Re: newbe question - roo with 2 network nterfaces

Can you guarantee that the interface is not transmitting or is it being
perceived as not transmitting ? IE: you can run tcpdump on the IP
interface in question, and traffic that is supposed to be sourced from
the interface in fact is not transmitted at all ? Best to verify this
using targets on the same IP subnet / broadcast domain to eliminate
routing changes/problems. Need to know whether the problem is real or
perceived prior to further troubleshooting; lots of things can happen
when Layer 2 participation changes and spanning tree is brought into the
equation.
