Hi,
I am using two PTP550 to connect my two locations to reduce the downtime.
Where both PTP550 connected to a single switch (CiscoSG300) at both sides. I enabled the STP in PTP550 as well as in the Cisco SG350 Switch.
While connecting both PTP550 two switch, my network stopped working. So I keep one ptp550 as disconnected and manually connecting when one link gets down.
CiscoSG300Switch--------1.PTP550Master + 2.PTP550Master----------------------------------------1.PTP550Slave + 2.PTP550Master------ CiscoSG300Switch.
Please help to work two PTP550 as an automatic failover.
Regards,
Prem Vishwakarma
