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 spanning-tree rstp mac-flush-threshold threshold-value Parameters threshold-value-Enter the threshold value for the number of flushes, from 0 to 65535. The default value is 65535. Default Not configured Command Mode CONFIGURATION Usage Information 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 non-default 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, 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. Example OS10(config)# spanning-tree rstp mac-flush-threshold 255 Supported Releases 10.4.0E(R1) or later spanning-tree rstp max-age Configures the time period the bridge maintains configuration information before refreshing the information by recomputing the RSTP topology. Syntax Parameters Default Command Mode Usage Information max-age seconds seconds - Enter a maximum age value in seconds, from 6 to 40. 20 seconds CONFIGURATION None 366 Layer 2
