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 this function on all its 10/100/1000 Ethernet Ports and on all its 10G interfaces. The 10/100/1000 ports support up to 32
port trunk groups with 2 to 8 ports in each group. A potential bit rate of 8000 Mbps can be achieved when using the
10/100/1000Mbps Ethernet ports. The 10G interfaces also support port trunk groups with 2 interfaces in each group.
Figure 3- 26. 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.
