spanning-tree rstp forward-time Configures a time interval for the interface to wait in the Blocking state or Learning state before moving to the Forwarding state. Syntax Parameters Default Command Mode Usage Information Example spanning-tree rstp forward-time seconds seconds - Enter the number of seconds an interface waits in the Blocking or Learning States before moving to the Forwarding state, from 4 to 30. 15 seconds CONFIGURATION None OS10(config)# spanning-tree rstp forward-time 16 Supported Releases 10.2.0E or later spanning-tree rstp hello-time Sets the time interval between generation and transmission of RSTP BPDUs. Syntax Parameters Default Command Mode Usage Information Example spanning-tree rstp hello-time seconds seconds - Enter a hello-time interval value in seconds, from 1 to 10. 2 seconds CONFIGURATION Dell EMC recommends increasing the hello-time for large configurations, especially configurations with multiple ports. OS10(config)# spanning-tree rstp hello-time 5 Supported Releases 10.2.0E or later spanning-tree rstp mac-flush-threshold Sets the flush indication threshold value on the RSTP instance. Syntax Parameters Default Command Mode Usage Information Example spanning-tree rstp mac-flush-threshold threshold-value threshold-value-Enter the threshold value for the number of flushes, from 0 to 65535. The default value is 65535. 65535 CONFIGURATION The threshold value indicates the number of flush indications to go before the flush interval timer is triggered. When flush indication threshold is set to the default value and the flush interval is set to a nondefault value, flushing occurs during the first flush indication trigger. When the flush indication threshold value is non-default (n) and flush interval value is non-default, port-based flushing is triggered until the threshold (n) is reached. Once the threshold is reached, the MAC flush timer starts. On timer expiry, the system triggers instance-based flushing. When the timer is running, all port-and-instance-based flushing is suppressed. The no form of the command sets the flush indication threshold to its default value. OS10(config)# spanning-tree rstp mac-flush-threshold 255 532 Layer 2
