Flush Mac Addresses After A Topology Change - Dell Force10 S4810P Configuration Manual

To enable EdgePort on an interface, use the following command:
Task
Enable EdgePort on an interface.
Verify that EdgePort is enabled on a port using the command
shown in Figure
FTOS Behavior: Regarding
1 If the interface to be shutdown is a port channel then all the member ports are disabled in the hardware.
2 When a physical port is added to a port channel already in error disable state, the new member port will also be disabled
in the hardware.
3 When a physical port is removed from a port channel in error disable state, the error disabled state is cleared on this
physical port (the physical port will be enabled in the hardware).
4 The command does not clear the error disabled state of the port or the hardware disabled state. The interface
reset linecard
continues to be disables in the hardware.
The error disabled state can be cleared with any of the following methods:
•Perform an
shutdown
•Disable the

•Disable spanning tree on the interface (

Flush MAC Addresses after a Topology Change

FTOS 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 command
which flushes MAC addresses upon every topology change notification. View the enable status of this
feature using the command
