MST Configuration
Command Usage
The MST region name (see
on page 339) and revision number are used to designate a
unique MST region. A bridge (i.e., spanning-tree compliant device such as this switch) can only
belong to one MST region. And all bridges in the same region must be configured with the same
MST instances.
Example
Console(config-mstp)#revision 1
Console(config-mstp)#

spanning-tree bpdu-filter
This command filters all BPDUs received on an edge port. Use the no form to disable this feature.
Syntax

Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
•
This command filters all Bridge Protocol Data Units (BPDUs) received on an interface to save
CPU processing time. This function is designed to work in conjunction with edge ports which
should only connect end stations to the switch, and therefore do not need to process BPDUs.
However, note that if a trunking port connected to another switch or bridging device is
mistakenly configured as an edge port, and BPDU filtering is enabled on this port, this might
cause a loop in the spanning tree.
•
Before enabling BPDU Filter, the interface must first be configured as an edge port with the
command.
Example
Console(config)#interface ethernet 1/5
Console(config-if)#spanning-tree edge-port
Console(config-if)#spanning-tree bpdu-filter
Console(config-if)#
