What is rldot1dStpFilterBpdu?

This read-write TruthValue setting controls whether the switch discards (filters) incoming Spanning Tree BPDU frames on ports where STP is turned off. Administrators use it to prevent a device with STP disabled from forwarding BPDUs into a network segment, which can otherwise trigger unwanted topology changes elsewhere. For example, on an access switch where STP has been disabled for a legacy device, an admin would set this to true(1) so any stray BPDUs the device generates are dropped instead of relayed.

Examples
