AT ${WORK} we have a couple of stacked Dell PowerSwitch S4048-ON running PVST STP connected to a Cisco switch running rapid-PVST STP. TLDR; port-channels on the Dells needs portmode hybrid in addition to switchport to enable VLAN 1, and it helps to ignore “invalid” PVST-BPDUs by adding no spanning-tree pvst err-disable cause invalid-pvst-bpdu to the […]
