Command Mode
CONFIGURATION
Usage Information
The threshold value indicates the number of port-based flush requests allowed to be invoked before starting the flush optimization. When the flush interval value is non-zero, port-and-instance-based flushing is triggered until the threshold is reached. Once the threshold is reached, MAC-flush timer starts. On timer expiry, the system triggers VLAN-based flushing. When the timer is running, any port-and-vlan-based flushing is suppressed. The no form of the command resets the flush indication threshold of the specific instance to its default value.
Example 
OS10(config)# spanning-tree vlan 100 mac-flush-threshold 255
Supported Releases
10.4.0E(R1) or later
