Trunk group overview
11
• Make sure the device on the other end of the trunk link can support the same number of ports
in the link. For example, if you configure a three-port trunk group on the device and the other
end is a different type of switch, make sure the other switch can support a three-port trunk
group.
• All the ports must be connected to the same device at the other end.
• All trunk group member properties must match the lead port of the trunk group with respect to
the following parameters:
• port tag type (untagged or tagged port)
• statically configured port speed and duplex
• QoS priority
To change port parameters, you must change them on the primary port. The software
automatically applies the changes to the other ports in the trunk group.
Trunk group configuration examples
Figure 76 shows some examples of valid 2-port trunk group links between devices. The trunk
groups in this example are switch trunk groups between two devices. Ports in a valid 2-port trunk
group on one device are connected to two ports in a valid 2-port trunk group on another device. The
same rules apply to 3-port, 4-port, etc., trunk groups.
