Port link aggregations can be used to increase the bandwidth of a network connection or to ensure fault recovery. Link aggregation lets you group up to 4 consecutive ports into a single dedicated connection between any two the Switch or other Layer 2 switches. However, before making any physical connections between devices, use the Link aggregation Configuration menu to specify the link aggregation on the devices at both ends. When using a port link aggregation, note that:
。The ports used in a link aggregation must all be of the same media type
。The ports that can be assigned to the same link aggregation have certain other restrictions (see below).
。Ports can only be assigned to one link aggregation.
。The ports at both ends of a connection must be configured as link aggregation ports.
。None of the ports in a link aggregation can be configured as a mirror source port or a mirror target port.
。Enable the link aggregation prior to connecting any cable between the switches to avoid creating a data loop.
。Disconnect all link aggregation port cables or disable the link aggregation ports before removing a port link aggre- gation to avoid creating a data loop.
It allows a maximum of 4 ports to be aggregated at the same time and up to 2 groups. If the group is defined as a local static link aggregation group, then the number of ports must be the same as the group member ports.
