Dell EMC SmartFabric OS10 User Guide Release 10.5.0

As specified in IEEE 802.1w, OS10 assumes a port that runs in full-duplex mode is 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.

OS10 assumes a port that runs in half-duplex mode is a shared link, to which the fast transition feature is not applicable. Also, If you explicitly designate a port as a shared link, you cannot use the fast transition feature, regardless of the duplex setting.

To hasten the spanning-tree state transitions, you can set the link type to point-to-point. To set the link type to point-to-point:

• Use the following command in INTERFACE mode.
