The spoke SDP edge-port command is used to instruct STP to dynamically decide whether the spoke SDP is connected to another bridge.
If auto-edge is enabled, and STP concludes there is no bridge behind the spoke SDP, 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 Spoke SDP edge port).
Valid values for spoke SDP auto-edge are enabled and disabled, with enabled being the default.
CLI syntax:
config>service>vpls>spoke-sdp>stp#
[no] auto-edge
