Link Aggregation

Understanding Port Trunk Groups
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline.
The Switch supports up to 32 port trunk groups with two to eight ports in each group. A potential bit rate of 8000
Mbps can be achieved.
The Switch treats all ports in a trunk group as a single port. Data transmitted to a specific host (destination address)
will always be transmitted over the same port in a trunk group. This allows packets in a data stream to arrive in the
same order they were sent.
Link aggregation 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.
Link aggregation is most commonly used to link a bandwidth intensive network device or devices, such as a server,
to the backbone of a network.
The Switch allows the creation of up to 32 link aggregation groups, each group consisting of 2 to 8 links (ports).
The (optional) Gigabit ports can only belong to a single link aggregation group.
occurs. A lower Internal cost represents a quicker transmission. Selecting 0 (zero) for
this parameter will set the quickest route automatically and optimally for an interface.
Enter a value between 0 and 240 to set the priority for the port interface. A higher
priority will designate the interface to forward packets first. A lower number denotes a
higher priority.
