Port Trunking
Port Trunking allows you to group multiple Ethernet ports in parallel to increase link bandwidth. The
aggregated ports can be viewed as a physical port that has a bandwidth equal to the combined bandwidth of
each trunked port.The member ports of the same trunk group can balance the loading and backup for each
other. The Port Trunking feature is usually used when you need higher bandwidth for the network backbone.
This is an inexpensive way for you to transfer more data.
The aggregated ports can interconnect to the another switch that also supports Port Trunking. Comtrol
supports two types of port trunking:
•
Static Trunk
•
IEEE 802.3ad
There are some different descriptions for the port trunking. Different manufacturers may use different
descriptions for their products, like Link Aggregation Group (LAG), Link Aggregation Control Protocol,
Ethernet Trunk, or Ether Channel.
When the other end uses IEEE 802.3ad LACP, you should assign IEEE 802.3ad LACP to the trunk. When the
other end uses non-802.3ad, you can then use Static Trunk.
There are two pages for port trunking,
