Stp Switch Settings - D-Link DGS-3212SR User Manual

D-Link DGS-3212SR Layer 2 Gigabit Ethernet Switch
learning states. An edge port loses its status if it receives a BPDU packet, immediately becoming a normal
spanning tree port.
P2P Port
A P2P port is also capable of rapid transition. P2P ports may be used to connect to other bridges. Under RSTP,
all ports operating in full-duplex mode are considered to be P2P ports, unless manually overridden through
configuration.
802.1d/802.1w Compatibility
RSTP can interoperate with legacy equipment and is capable of automatically adjusting BPDU packets to 802.1d
format when necessary. However, any segment using 802.1 STP will not benefit from the rapid transition and
rapid topology change detection of 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.

STP Switch Settings

The Spanning Tree Protocol (STP) operates on two levels. On the switch level, the settings are globally
implemented. On the port level, the settings are implemented on a per user-defined Group of ports basis.
