stp transmit-limit (interface view)

stp transmit-limit (interface view)

Function

The stp transmit-limit command sets the maximum number of BPDUs that the current port can send in a specified period.

The undo stp transmit-limit command restores the default maximum BPDUs.

Format

stp transmit-limit packet-number

undo stp transmit-limit

Parameters

Parameter Description Value
packet-number

Specifies the maximum number of BPDUs that a port can send in a specified period.

The value is an integer that ranges from 1 to 255.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

On a network where a spanning tree protocol is enabled, a switching device periodically sends BPDUs to other devices in the same spanning tree with the interval of the Hello Time. Sending BPDUs periodically ensures that the spanning tree is stable. If the number of sent BPDUs are great in a specified period, excessive system and bandwidth resources will be consumed.

To prevent this problem from occurring, run the stp transmit-limit command to set the maximum number of BPDUs that can be sent by an interface in a specified period. In this manner, the BPDU sending speed is controlled, preventing excessive use of system and bandwidth resources by MSTP when the network topology flaps.

Precautions

After the stp transmit-limit command is configured, the maximum number of BPDUs sent in a specified period by the interface is determined by the set value.

Example

# Set the maximum BPDUs that GE0/0/1 can send in a specified period to 5.
