Two PTP550 - Failover

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.

Hi,

Do you have manageable switches on the both sides of the links?
I guess you can disable STP on PTP550s and leave it running on switches.
PTP550s will be transparent for STP.

Thank you.

Yes, both side has managed switch. 

I'll try the option to disable  STP in PTP550 and check the same. 

Thanks!
