Switching to the RSTP Mode

Switching to the RSTP Mode


If an interface on an RSTP-enabled device is connected to an STP-enabled device, the interface switches to the STP compatible mode.

If the STP-enabled device is powered off or disconnected from the RSTP-enabled device, or the STP-enabled device is switched to the RSTP mode, the interface does not automatically switch back to the RSTP mode. In any of these cases, run the stp mcheck command to switch the interface to the RSTP mode.
