Configure An Edgeport - Dell Force10 S4810P Configuration Manual

• Port priority influences the likelihood that a port will be selected to be a forwarding port in case that
several ports have the same port cost.
To change the port cost or priority of an interface, use the following commands:
Task
Change the port cost of an interface.
Range: 0 to 65535
Default: see Table 42-2.
Change the port priority of an interface.
Range: 0 to 15
Default: 128
View the current values for interface parameters using the
privilege mode. See

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
shutdown-on-violation
only is implemented, although the interface is placed in an Error Disabled state when receiving
bpduguard
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.
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 interface, use the following command:
