* Disabling global spanning tree (using the
no spanning-tree
command in CONFIGURATION
mode).
Example of Enabling an EdgePort on an Interface
To verify that EdgePort is enabled, use the
show config
command from INTERFACE mode.
Dell(conf-if-te-3/11)#spanning-tree mstp edge-port
Dell(conf-if-te-3/11)#show config
!
interface TenGigabitEthernet 3/11
no ip address

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.
