SPANNING TREE BPDU

spanning-tree bpdu

Overview Use this command in Global Configuration mode to configure BPDU (Bridge
Protocol Data Unit) discarding or forwarding, with STP (Spanning Tree Protocol)
disabled on the switch.
See the Usage note about disabling Spanning Tree before using this command,
and using this command to forward unsupported BPDUs unchanged for
unsupported STP Protocols.
There is not a no variant for this command. Instead, apply the discard parameter
to reset it back to the default then re-enable STP with spanning-tree enable
command.
Syntax
spanning-tree bpdu
{discard|forward|forward-untagged-vlan|forward-vlan}
Default The discard parameter is enabled by default.
Mode Global Configuration
Usage You must first disable Spanning Tree with the
before you can use this command to then configure BPDU discarding or
forwarding.
This command enables the switch to forward unsupported BPDUs with an
unsupported Spanning Tree Protocol, such as proprietary STP protocols with
unsupported BPDUs, by forwarding BDPU (Bridge Protocol Data Unit) frames
unchanged through the switch.
When you want to revert to default behavior on the switch, issue a spanning-tree
bdpu discard command and re-enable Spanning Tree with a s panning-tree
enable command.
