4.6.3 Link Aggregation
Link aggregation can be used to increase the bandwidth of a network connection or to ensure fault recovery. Link
aggregation lets you group up consecutive ports into a single dedicated connection between any two of the
Switches or other Layer 2 switches. However, before making any physical connections between devices, use the
Link Aggregation 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 (RJ-45, 100 Mbps fiber).
。 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.
。 All of the ports in a link aggregation have to be treated as a whole when moved from/to, added or deleted
from a VLAN.
。 The Spanning Tree Protocol will treat all the ports in a link aggregation as a whole.
。 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
aggregation to avoid creating a data loop.
It allows a maximum of four ports to be aggregated at the same time and up to 4 groups. If the group is defined as
a LACP static link aggregationing group, then any extra ports selected are placed in a standby mode for
redundancy if one of the other ports fails. If the group is defined as a local static link aggregationing group, then
the number of ports must be the same as the group member ports.
