Link Aggregation (Port Trunking)
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data pipeline.
NOTE: In the current DGS-3024 firmware version, only Static Type Link
Agggregation is supported. LACP Type Link Aggregation (802.3ad) is not
yet supported.
Static Type Link Aggregation is usually referred as “Port Trunking.” In this
section, the terms “Link Aggregation” and “Port Trunking” will be used
synonymously.
The DGS-3024 supports up to four port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can
be achieved.
Figure 7- 6. Example of Port Trunk Group
The Switch treats all ports in a trunk group as a single port. Data transmitted to a specific host 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
uplinked ports of the port trunking group.
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.
Port trunking is most commonly used to link a bandwidth intensive network device or devices, such as a server, to the
backbone of a network.
