Link aggregation groups multiple ports together in parallel to act as a single logical link. Aggregation-enabled devices treat all physical links (ports) in an aggregation group entirely as a single logical link (port). Member ports in an aggregation group share egress/ingress traffic load, delivering a bandwidth that is multiple of a single physical link. The feature is available is at Manage > Switch < Details > Link Aggregation
To Configure trunk , you must select aggregation type . Select from the following options:
LACP: LACP is a dynamic protocol which helps to automate the configuration and maintenance of LAG’s. The main purpose of LACP is to automatically configure individual links to an aggregate bundle, while adding new links and helping to recover from link failures if the need arises. LACP can monitor to verify if all the links are connected to the authorized group. LACP is a standard in computer networking, hence LACP should be enabled on the Switch's trunk ports initially in order for both the participating Switches/devices that support the standard to use it.
Static: Static configuration is used when connecting to a switch that doesn't support LACP.
Disable : Disable the trunk that you configured previously.
Then select the Member Ports to add into the trunk group. There are two ways to select the ports
Click on the port picker to select multiple ports.
2. Click Pencil icon to input port numbers
After you complete the trunk settings , remember to click Apply to take effect .
