D-Link DES-3326SR Layer 3 Switch
The following fields are configured in the STP Port Settings – Edit menu:
Parameter Description
Cost A Port Cost can be set from 1 to 200000000 . The lower the
number, the greater the probability the port will be chosen to
forward packets.
Default port cost:
100Mbps port = 200000
Gigabit ports = 20000
Priority <128> A Port Priority can be from 0 to 240 . The lower the number,
the greater the probability the port will be chosen as the Root
Port.
Migration <No>
Select Yes or No. Choosing Yes will enable the port to
migrate from 802.1d STP status to 802.1w RSTP status.
RSTP can coexist with standard STP, however the benefits of
RSTP are not realized on a port where an 802.1d network
connects to an 802.1w enabled network. Migration should be
enabled (yes) on ports connected to network stations or
segments that will be upgraded to 802.1w RSTP on all or
some portion of the segment.
Edge <No> Select True or False. Choosing true designates the port as an
edge port. Edge ports cannot create loops, however an edge
port can lose edge port status if a topology change creates a
potential for a loop. An edge port normally should not receive
BPDU packets. If a BPDU packet is received it automatically
loses edge port status. False indicates the port does not have
edge port status.
P2P <Yes> Select True or False. Choosing true indicates a point-to-point
(p2p) shared link. These are similar to edge ports however
they are restricted in that a p2p port must operate in full-
duplex. Like edge ports, p2p ports transition to a forwarding
state rapidly thus benefiting from RSTP.
Configure Ports from __ to __ A consecutive groups of ports may be configured starting with
the selected port.
