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
number of port trunk groups, supported by the Switch, is equal to half of the total physical ports on the Switch. Each
port trunk group can have two to eight physical ports assigned to each group.
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.

will designate the interface to forward packets first. A lower number denotes a higher
priority.
