Figure 9-4. VLAN Port Settings

LAGs

A Link Aggregated Group (LAG) is composed of ports with the same speed, set to full-duplex

operation. Up to six Aggregated Links may be defined, each with up to four member ports, to form

a single Link Aggregated Group (LAG). This enables:

•

Fault tolerance protection from physical link disruption

•

Higher bandwidth connections

•

Improved bandwidth granularity

•

High bandwidth server connectivity

With the departmental PowerConnect 2708/2716/2724 switches installed, network redundancy and

improved traffic performance are facilitated. The PowerConnect device serves to connect the

departmental groups of users to another switch that is located on another floor. In addition, LAGs

are used to ensure that a backup, in case one line is disabled.

The following figure illustrates the concept of Aggragated Links in the switch.
