View System view

Parameters number: Maximum number of times the device deletes forwarding address entries within a certain period of time immediately after it receives TC-BPDUs, in the range of 1 to 255.

Description Use the stp tc-protection threshold command to configure the maximum number of times the device deletes forwarding address entries within 10 seconds immediately after it receives TC-BPDUs.

Use the undo stp tc-protection threshold command to restore the default configuration.

By default, the device limits the maximum number of times of deleting forwarding address entries within a certain period of time immediately after it receives TC-BPDUs to 6 times.

Examples # Set the maximum number of times the device deletes forwarding address entries within a certain period of time immediately after it receives TC-BPDUs to 10.

stp timer forward-delay

Syntax stp timer forward-delay centi-seconds

undo stp timer forward-delay

View System view

Parameters centi-seconds: Forward delay, in the range 400 to 3,000 (in centiseconds). This argument must be a multiple of 100.

Description Use the stp timer forward-delaycommand to set the forward delay timer of the device.

Use the undo stp timer forward-delaycommand to restore the forward delay timer of the device to the default setting.

By default, the forward delay timer is set to 1,500 centiseconds.

In order to prevent temporary loops, a port must go through an intermediate state, the learning state, before it transitions from the discarding state to the
