Aggregating Ports
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. The device supports up to four LAGs, each having six members.
Each LAG is composed of ports of the same speed, set to
The device provides LAG Load Balancing based on both source MAC addresses and destination MAC addresses.
Aggregated Links are treated by the system as a single logical port. Specifically, the Aggregated Link has similar port attributes to a
The following guidelines should be followed when adding ports to a LAG:
•There is no Layer 3 interface defined on the port.
•The port does not belong to any VLAN.
•The port does not belong to any other LAG.
•The port is not a mirrored port.
•The port's 802.1p priority is equal to LAGs 802.1p priority.
•QoS Trust is not disabled on the port.
•GVRP is not enabled.
The device uses a hash function to determine which frames are carried on which
Each Aggregated Link has an Aggregated Link Port Type, including Gigabit Ethernet ports. Ports can be added to an Aggregated Link only if they are the same port type. When ports are removed from an Aggregated Links, the ports revert to the original port settings. To open the Link Aggregation page, click Switch→ Link Aggregation in the tree view.
