NOTE
Earlier implementation of Rapid Spanning Tree Protocol (RSTP), which was 802.1W Draft 3 provides
only a subset of the IEEE 802.1W standard; whereas the 802.1W RSTP feature provides the full
standard. The implementation of the 802.1W Draft 3 is referred to as RSTP Draft3. RSTP Draft3 will
continue to be supported on Dell devices for backward compatibility. Users currently using RSTP
Draft 3 should migrate to 802.1W.
