Port LACP Trunking
Figure 7-6. Port LACP Trunking Settings window
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 8 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.
