A P2P port is also capable of rapid transition. P2P ports may be use d to connect to oth er bridges. Under RST P, all
ports operating in full-duplex mode are considered to be P2P ports, unless manually overridden through configuration.
802.1D and 802.1w Compatibility RSTP can interoperate with legacy equipment and is capable of autom atically adjusting BPDU packets to 80 2.1D
format when necessary. However, any segment using 802.1D STP will not benef it from the rapid trans ition and rapid
topology change detection of RSTP. The protocol also provides for a var iable used for migration in the event that
legacy equipment on a segment is updated to use RSTP.
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 gro up of ports basis.
