Enabling the device to log events of detecting or
receiving TC BPDUs
About spanning tree TC BPDU event logging
This feature allows the device to generate logs when it detects or receives TC BPDUs. This feature
applies only to PVST mode.
Procedure
1.
Enter system view.
system-view
2.
Enable the device to log events of receiving or detecting TC BPDUs.
stp log enable tc
By default, the device does not generate logs when it detects or receives TC BPDUs.
Disabling the device from reactivating edge ports
shut down by BPDU guard
About disabling the device from reactivating edge ports shut down by BPDU guard
BPDU guard shuts down edge ports that have received configuration BPDUs and notifies the NMS of
the shutdown event.
The device reactivates the ports that have been shut down when the port status detection timer
expires. You can set this timer by using the
shutdown-interval
command. For more information
about this command, see device management commands in
Fundamentals Command Reference
.
Restrictions and guidelines
This feature prevents the device from reactivating edge ports shut down by BPDU guard after this
feature is configured. The device does not bring up the shutdown ports if you execute the
undo stp
port shutdown permanent
command. To bring up these ports, use the
undo shutdown
command.
Procedure
1.
Enter system view.
system-view
2.
Disable the device from reactivating edge ports shut down by BPDU guard.
stp port shutdown permanent
By default, the device reactivates an edge port shut down by BPDU guard after the port status
detection timer expires.
Enabling BPDU transparent transmission on a
port
Restrictions and guidelines
Perform this task to enable a port to transmit BPDUs transparently. Whether the spanning tree
protocols are enabled on a port does not affect the BPDU transparent transmission feature.
