Question around oneway traffic patterns in a ring design
Say I have a ring of 4 switches interconnected with WDM equipment over dualfiberpairs
Between switch 1 and 2 I loose the link, so the switch flags the port as down Local fault.
However the WDM equipment manages to have one TX/RX active in one direction only. But the switch acts as if the ring is down and opens the secondary port on the master.
In this scenario traffic would still arrive at the masters secondary port but just one-way.
My question around this. Would this cause a loop ?
Switch 1 would still receive all the traffic from switch 2 but it could not send anything back since its one-way traffic only.
