Managing STP BPDU After Disabling LLDP
Netvisor ONE optimizes STP BPDUs by not sending BPDUs on any ports if the ports are not switch ports. This is the default setting for the parameter, bpdus-bridge-port.
If you do not configure LLDP, Netvisor One does not detect host ports and does not t send BPDU packets. As a result, both ports are in Forwarding state.
When you add the parameter, bpdus-all-ports, to allow sending BPDUs on ports even if ports are not detected, unless the port is configured as an edge port. On a switch with a port connected to itself with this configuration one of the ports goes into a Discarding state.
