Duplex: In TP ports with 10Mbps/100Mbps port speed and select “Manual” as port type, you can
further specify the current operation Duplex mode (full or half duplex) of the port(s).
Flow Control: Enable or disable the flow control.
Description: Enter a unique description for the port. Up to 35 alphanumeric characters can be
accepted.
4.4.3 Link Aggregation
Link aggregation is an inexpensive way to set up a high-speed backbone network that transfers
much more data than any one single port or device can deliver without replacing everything and
buying new hardware.
For most backbone installations, it is common to install more cabling or fiber optic pairs than
initially necessary, even if there is no immediate need for the additional cabling. This action is
taken because labor costs are higher than the cost of the cable and running extra cable reduces
future labor costs if networking needs changes. Link aggregation can allow the use of these extra
cables to increase backbone speeds with little or no extra cost if ports are available.
This Managed switch supports 2 link aggregation modes: static Port Trunk and dynamic Link
Aggregation Control Protocol (LACP) using the IEEE 802.3ad standard. These allow several
devices to communicate simultaneously at their full single-port speed while not allowing any one
single device to occupy all available backbone capacities.
Click Link Aggregation folder from the Switch Management menu and then three options within
this folder will be displayed.
1. Distribution Rule: Configure the distribution rule of Port Trunking group(s).
2. Port Trunking: Create, edit or delete port trunking group(s).
3. LACP Port Configuration: Set up the configuration of LACP on all or some ports.
