• When you remove a physical port from a port channel in the Error Disable state, the error disabled
state is cleared on this physical port (the physical port is enabled in the hardware).
• You can clear the Error Disabled state with any of the following methods:
• Use the
shutdown
command on the interface.
• Disable the
shutdown-on-violation
command on the interface (using the
no spanning-
tree stp-id portfast [bpduguard | [shutdown-on-violation]]
command).
• Disable spanning tree on the interface (using the
no spanning-tree
command in INTERFACE
mode).
• 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.

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.
