802.1D-1998/802.1D-2004/802.1Q-2005 Compatibility
MSTP or RSTP can interoperate with legacy equipment and is capable of automatically adjusting BPDU packets to 802.1D-1998
format when necessary. However, any segment using 802.1D-1998 STP will not benefit from the rapid transition and rapid
topology change detection of MSTP or RSTP. The protocol also provides for a variable used for migration in the event that legacy
equipment on a segment is updated to use RSTP or MSTP.
The Spanning Tree Protocol (STP) operates on two levels:
1.
On the switch level, the settings are globally implemented.
2.
On the port level, the settings are implemented on a per-user-defined group of ports basis.
