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. spanning-tree link-type point-to-point RSTP commands show spanning-tree active Displays the RSTP configuration and information for RSTP-active interfaces.
