We are using dell S4048-ON switches in VLT setup to connect our servers in port-channel setup. We noticed that port flapping of interfaces sends out spanning tree changes throughout the infrastructure which in turn makes switches send "reset" packets for server ssh connections (thus disconnecting them). To protect against that we set "bpduguard" setting on port-channel as well as physical ports. Bpduguard command protects from spanning tree changes but we noticed that this command breaks port-channels on the switches and they begin to work through physical interfaces instead of port-channel interfaces (even though the server believes it to still be in port-channel setup). Without bpduguard command port-channels establish correctly on the switch but to prevent spanning tree changes we must keep it on. Is there perhaps a proper way of setting bpduguard on port-channels and their physical ports?
