D-Link DES-3326S Layer 3 Switch The following fields are configured in the STP Port Settings - Edit menu: Parameter Description Cost Priority Migration Edge P2P Configure Ports from __ to __ 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 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. 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. 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. 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. A consecutive groups of ports may be configured starting with the selected port. 65

D-Link DES-3326S 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.
