BPDU Control Configure the way to treat BPDUs (Bridge Protocol Data Units) received on this port. You must
activate bridging control protocol transparency in the Switch Setup screen first.
Select Peer to look at the information in the received BPDUs. For example, the root bridge’s
existence, if any bridge was added or removed from the STP (Spanning Tree Protocol)
network, if any loop occurred in the STP network.
Select Tunnel to add the incoming port’s PVID on the received BPDUs and then forward them
to the next Switch.
Select Discard to drop all BPDUs received on this port. Set this only on an edge port of a STP
network.
Select Network to forward VLAN-tagged BPDUs to the next Switch directly and handle VLAN-
untagged BPDUs as the Peer option.
See Section 14.1.2 on page 161 for more information about BPDU.
