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 DGS-3312SR supports up to six port trunk groups with two to eight ports in each group. A potential bit rate of 8000
Mbps can be achieved.
Figure 4- 8. Example of Port Trunk 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.
