This feature helps to automatically determine a port is an edge port or non-edge port. If no BPDU is received for a period of time on auto edge enabled ports the switch marks those ports as edge ports.
If BPDU is received then the switch marks those ports as non-edge ports.
The condition statement is used to determine a port is an edge or non-edge port by Bridge detection state machine.
The Edge Delay timer - The time remaining, in the absence of a received BPDU, before this port is identified as Edge Port.
PortEnabled - Will say that the port is enabled/disabled.
AdminEdge - Configuration of Edge port by administrator.
AutoEdge - Configuration of Auto edge feature is enable or disabled.
SendRstp - Variable Transmit state machine used to identify the BPDU type.
Proposing - Set by a Designated Port that is not Forwarding, and conveyed to the Root
Port or Alternate Port of a neighboring Bridge in the Proposal flag of an RST BPDU
