Filtering – Filters BPDU packets when Spanning Tree is disabled on an interface or globally on the device. Filtering is used when a bridge interconnects two regions and there is a need to have a separate spanning tree for each region. Filtering the BPDU in the bridge connecting the two regions will serve this purpose.

Flooding – Floods BPDU packets when Spanning Tree is disabled on an interface or globally on the device. This is the default value.

Bridging – Forwards BPDU packets (subject to ingress and egress VLAN rules) when Spanning Tree is disabled on an interface or globally on the device.
