spanning-tree rpvst-filter

Syntax

spanning-tree rpvst-filter no spanning-tree rpvst-filter

描述

Enables the RPVST filter for the interface.

When the RPVST filter is enabled, the ingressing RPVST proprietary BPDUs are dropped after copying to CPU whereas the standard IEEE RPVST BPDUs are still allowed. This helps in preventing the flooding of RPVST proprietary BPDUs under an MSTP-RPVST interop environment.

NOTE:

If the neighboring switch is running RPVST then this pair of switches will not converge as RPVST BPDUs will not reach them.

If enabling RPVST filter causes a high traffic load, shutdown the port and reconfigure the BPDU filter with the CLI command:no spanning tree rpvst-filter.

RPVST filter is disabled by default.

Command context

Example

On the 6400 Switch Series, interface identification differs.

Enabling the RPVST filter on interface 1/1/1:

switch#configure terminalswitch(config)#interface 1/1/1switch(config-if)#spanning-tree rpvst-filter

Disabling RPVST filter on interface 1/1/1:

switch#configure terminalswitch(config)#interface 1/1/1switch(config-if)#没有扩充树rpvst-filter
