D-Link DES-3326SR Layer 3 Switch
Edge Port
The edge port is a configurable designation used for a port that is directly connected to a segment where a loop
cannot be created. An example would be a port connected directly to a single workstation. Ports that are
designated as edge ports, transition to a forwarding state immediately without going through the listening and
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.
802.1w/802.1d 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.
Configure STP Switch Settings
Spanning Tree Protocol 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.
