Dell EMC SmartFabric OS10 User Guide Release 10.5.0

• auto — Enter the keyword to sets the link-type based on the duplex setting of the interface.
• point-to-point—Specifies that the interface is a point-to-point or full-duplex link.
• shared—Specifies that the interface is a half-duplex medium.

As specified in IEEE 802.1w, OS10 assumes a port that runs in full-duplex mode as a point-to-point link. A point-to-point link transitions to forwarding state faster. By default, OS10 derives the link-type of a port from the duplex mode. You can override the duplex mode using the spanning-tree link-type command.

As half-duplex mode is considered as a shared link, the fast transition feature is not applicable for shared links. If you designate a port as a shared link, you cannot use the fast transition feature, regardless of the duplex setting.
