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.
