configure stpd bpdu-forwarding

configure stpd bpdu-forwarding [on | off]


This command specifies whether to forward or drop BPDUs when STP is disabled.

Syntax Description

bpdu-forwarding Specifies forwarding or discarding spanning tree BPDUs when STP is disabled.
on Forward STP BPDUs when spanning tree is disabled (default).
off Drop STP BPDUs when spanning tree is disabled.


The default is on.

Usage Guidelines

STP must be disabled globally to disable BPDU forwarding; otherwise, an error message appears:
Error: All Spanning Tree Domains must be disabled globally before configuring stpd bpdu-forwarding off. 
When the BPDU forwarding is off and you try to configure the filter method using the configure stpd filter-method [system-wide| port-based] command, the following error message appears:
Error: Spanning Tree Forwarding must be enabled globally before configuring filter-method.  


The following example disables BPDU forwarding when STP is disabled:
