But the switch acts as if the ring is down and opens the secondary port on the master. <BR /> <BR /> In this scenario traffic would still arrive at the masters secondary port but just one-way. <BR /> <BR /> My question around this. Would this cause a loop ? <BR /> Switch 1 would still receive all the traffic from switch 2 but it could not send anything back since its one-way traffic only. <BR /> <BR /> Makes sense?
