Description

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.

Default

Usage Guidelines

STP must be disabled globally to disable BPDU forwarding; otherwise, an error message appears:

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:
