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.

This example uses the following steps:
1 Enable MSTP globally and set the region name and revision map MSTP instances to the VLANs.
2 Assign Layer-2 interfaces to the MSTP topology.
3 Create VLANs mapped to MSTP instances tag interfaces to the VLANs.
