Configure An Edgeport - Dell Force10 C150 Configuration Manual

Configure an EdgePort

The EdgePort feature enables interfaces to begin forwarding traffic approximately 30 seconds sooner. In
this mode an interface forwards frames by default until it receives a BPDU that indicates that it should
behave otherwise; it does not go through the Learning and Listening states. The

receiving the BPDU, the physical interface remains up and spanning-tree will drop packets in the hardware
after a BPDU violation. BPDUs are dropped in the software after receiving the BPDU violation. This
feature is the same as PortFast mode in Spanning Tree.
Caution:
Configure EdgePort only on links connecting to an end station. EdgePort can cause loops if it is enabled
on an interface connected to a network.
To enable EdgePort on an MSTP-enabled 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).

The error disabled state can be cleared with any of the following methods:
