Figure 6-64. STP Port Settings screen
The STP port settings that can be configured are:
•
Configure Port from [ ] to [ ] –
Enter the desired ports in the two fields offered.
•
Port Cost –
A Port Cost can be set from
1
to
65535
. The lower the number, the greater the probability the
port will be chosen to forward packets.
•
Priority
–
A Port Priority can be from
0
to
255
. The lower the number, the greater the probability the port
will be chosen as the Root Port.
•
Fast STP –
Toggle between
Normal
and
Fast
.
Port Trunking
Port trunking allows several ports to be grouped together and to act as a single link. This gives a bandwidth that is a
multiple of a single link’s bandwidth.
Trunking, also known as link aggregation, is most commonly used to link a bandwidth intensive network device or devices
– such as a server or server farm – to the backbone of a network.
Note:
The DGS-3308 allows the creation of up to 4 port trunk groups, each consisting of up to 4 links
(ports). The aggregated links must be contiguous (they must have sequential port numbers) and
all of the ports in the group must be members of the same VLAN. Further, the linked ports
must all be of the same speed and should be configured as full duplex.
The configuration of the lowest numbered port in the group becomes the configuration for all of the ports in the aggregation
group. This port is called the base port of the group, and all configuration options – including the VLAN configuration –
that can be applied to the base port are applied to the entire link aggregation group.
