Understanding Port Trunk Groups
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline. DES-3800 Series
supports up to 32 port trunk groups with 2 to 8 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.
NOTE: If any ports within the trunk group become disconnected, packets intended for the
disconnected port will be load shared among the other unlinked ports of the link aggregation
group.
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.
