Flush MAC Addresses after a Topology Change
Dell Networking OS has an optimized MAC address flush mechanism for RSTP, MSTP, and PVST+ that
flushes addresses only when necessary, which allows for faster convergence during topology changes.
However, you may activate the flushing mechanism defined by 802.1Q-2003 using the tc-flush-
standard
command, which flushes MAC addresses after every topology change notification.
To view the enable status of this feature, use the show running-config spanning-tree mstp
command from EXEC Privilege mode.
MSTP Sample Configurations
The running-configurations support the topology shown in the following illustration.
The configurations are from Dell Networking OS systems.
