Command Reference | Layer 2 functions | 195 [Note] This command can be specified only for LAN/SFP port. In order to enable the loop detection function, the loop detection function must be enabled on the entire system in addition to this command. Even if the loop detection function is enabled, the loop detection function does not operate on the following interfaces. • LAN/SFP port on which the spanning tree function is operating. However, because a Forwarding port transmits and receives LDF, the loop detection will operate if misconnection or another issue causes a loop to occur. • LAN/SFP port that is operating as a trunk port for which native VLAN is not specified • LAN/SFP port that is inside a logical interface The following table shows which function is enabled depending on the settings of the spanning tree function (STP) and the loop detection function (LPD). Interface LPD disabled LPD enabled STP disabled STP enabled STP disabled STP enaabled STP disabled - LPD disabled STP enabled - System STP disabled - LPD enabled STP enabled - - - - STP - STP - LPD LPD STP LPD STP [Example] Enable the loop detection function of LAN port #1.
