Port Trunking Overview
A port trunk is an economical way for you to increase the bandwidth
between the Ethernet switch and another networking device, such as a
network server, router, workstation, or another Ethernet switch. A port
trunk is a group of ports that have been grouped together to function as
one logical path. A port trunk increases the bandwidth between the switch
and the other network device and is useful in situations where a single
physical link between the devices is insufficient to handle the traffic load.
Static Port Trunk
Overview
A static port trunk consists of two to eight ports on the switch that function
as a single virtual link between the switch and another device. A static port
trunk improves performance by distributing the traffic across multiple ports
between the devices and enhances reliability by reducing the reliance on a
single physical link.
A static trunk is easy to configure. You simply designate the ports on the
switch that are to be in the trunk and the management software on the
switch automatically groups them together.
The example in Figure 14 illustrates a static port trunk of four links
between two AT-GS950/48 Gigabit Ethernet Smart Switches.
Figure 14. Static Port Trunk Example
Network equipment vendors tend to employ different techniques to
implement static trunks. Consequently, a static trunk on one device might
not be compatible with the same feature on a device from a different
manufacturer. For this reason static trunks are typically employed only
between devices from the same vendor. That is not to say that an Allied
Telesis layer 2 managed switch cannot form a static trunk with a device
from another manufacturer; but there is the possibility that the
implementations of static trunking on the two devices might not be
compatible.
