Configure Trunk

To configure a port trunking group, highlight Configure TRUNK on the Configuration menu and press
Enter.
Link aggregation, or 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.
The switch allows the creation of up to 6 port trunking groups, each group consisting of up to 16 links
(ports). The trunked ports can be non-continuous (that is, have non-sequential port numbers). All of
the ports in the group must be members of the same VLAN. Further, the trunked ports must all be of
the same speed and should be configured as full duplex.
The configuration of the lowest numbered port in the group becomes the configuration for all of the
ports in the port trunking group. This port is called the Master Port of the group, and all configuration
options – including the VLAN configuration – that can be applied to the Master Port are applied to the
entire port trunking group.
Load balancing is automatically applied to the ports in the trunked group, and a link failure within the
group causes the network traffic to be directed to the remaining links in the group.
The Spanning Tree Protocol will treat a port trunking group as a single link, on the switch level. On the
port level, the STP will use the port parameters of the Master Port in the calculation of port cost and in
determining the state of the port trunking group. If two redundant port trunking groups are configured
