RSTP Configuration Commands in Interface Configuration
Mode
rapid-spanning-tree all
The rapid-spanning-tree all command, in Interface Configuration mode, displays the current
status of rapid-spanning-tree parameters for all the switch's logical interfaces. The command
is equivalent to the rapid-spanning-tree interface all command in Protocol Configuration
mode. See also Displaying Port Rapid-Spanning-Tree Topology Settings.

rapid-spanning-tree edge-port
The rapid-spanning-tree edge-port command, in Interface Configuration mode, changes the
admin status. The no form of this command disables the admin status.
The EdgePort parameter is controlled by the RSTP state machine and the Command Line
Interface (CLI):
Admin EdgePort
The admin EdgePort parameter can be set by the CLI on a per-Port basis in order to
indicate that a given Port is permitted to transit directly to the Forwarding Port State when
a Port becomes Designated.
This functionality is provided in order to permit Bridge Ports that are (administratively)
known to be at the edge of the Bridged LAN to transition to Forwarding without delay.
However, as the presence of a Bridge on a Port that has been marked as an edge Port
could potentially cause a loop in the active topology, it is necessary to qualify the value of
the administrative state variable according to the port's knowledge of whether or not any
BPDUs have been received on the Port.
EdgePort
The Bridge Detection state machine controls the value of the corresponding
operational state variable, operational EdgePort, which may be used in order to
determine whether a port that becomes Designated is permitted to transit directly to
Forwarding. A value of enabled in the show commands indicates that this state transition
