The SAP edge-port command is used to instruct STP to dynamically decide whether the SAP is connected to another bridge.
If auto-edge is enabled, and STP concludes there is no bridge behind the SAP, the OPER_EDGE variable is dynamically set to true. If auto-edge is enabled, and a BPDU is received, the OPER_EDGE variable is dynamically set to true (see SAP Edge Port).
Valid values for SAP auto-edge are enabled and disabled with enabled being the default.
CLI syntax:
config>service>vpls>sap>stp#
[no] auto-edge
