I have 2 S3048-ON configured with VLT (virtual link trunk), and a Dell 5548 connected to one of the S3048-ON (tried both one and two cables).
All switches are configured with RSTP, and have configured priorities.
But both S3048-ON and Dell 5548 thinks they’re root.
I can’t seem to trigger Dell 5548 to “surrender” and not be root bridge.
Haven’t seen this behavior before. Any insights ?
Attached some screenshots.
