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 five port trunk groups with two to eight ports in each group. A potential bit rate of 8000 Mbps can be achieved.
Figure 7- 14. 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.
NOTE:
If any ports within the trunk group become disconnected, packets intended for
the disconnected port will be load shared among the other linked 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.
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 five 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. All of the ports in the group must be members of the same
