Hello, I have recently noticed a possible bug on DELL Powerconnect 6248 (fw: 3.3.9.1)
I run MST with 1 instance and bpdu-filter disabled. I noticed that when a port is enabled via dot1x mac-based authentication that port does NOT send BPDUs even though I can see with "show interface detail ethernet X" the "BPDU: sent" counter increasing
When the port is not authenticated with dot1x everything works and I receive the BPDUs.
