Port Trunking Overview
Port trunking is an economical way for you to increase the bandwidth
between two Ethernet switches. For the AT-8400 Series switch, a port
trunk can consists of up to eight ports that have been grouped together
to function as one logical path. A port trunk increases the bandwidth
between switches and is useful in situations where a single physical data
link between switches is insufficient to handle the traffic load.
A port trunk sends packets from a particular source to a particular
destination over the same link within the trunk. A single link is
designated for flooding broadcasts and packets of unknown destination.
The example in Figure 35 consists of a 1,000 Mbps port trunk with four
data links between two AT-8400 switches.
