Port Aggregation optimizes port usage by linking a group of ports together to form a single Link Aggregated Group (LAG). Port Aggregation multiplies the

bandwidth between the devices, increases port flexibility, and provides link redundancy. Both the PowerConnect 3324 and PowerConnect 3348 support up to

six LAGs, and eight ports per LAG per stack or stand-alone unit.

Each LAG is composed of ports of the same speed, set to full-duplex operations. Ports in a LAG, can be of different media types (UTP/Fiber, or different fiber

types), provided they operate at the same speed.

Aggregated links can be assigned manually or automatically by enabling the Link Aggregation Control Protocol (LACP) on the relevant links. PowerConnect

3324/3348 provides LAG Load Balancing based on both source MAC addresses and destination MAC addresses.

Aggregated links are treated as a single logical port by the system. Specifically, the Aggregated link has similar port attributes to a non-aggregated port,

including auto-negotiation, speed, duplex setting, and so forth.

PowerConnect 3324/3348 supports both static LAGs and Link Aggregation Control Protocol (LACP) LAGs. LACP LAGs negotiate aggregated port links with other

LACP ports located on a different device. If the other device ports are also LACP ports, the devices establish a LAG between them.

Use the following guidelines when adding ports to a LAG for either a standalone or a stacking configuration:

No Layer 3 interface is defined on the port.

The port does not belong to any VLAN.
