1.1 Overview

Link aggregation means aggregating several links together to form an aggregation

group, so as to implement outgoing/incoming load sharing among the member ports in

the group and to enhance the connection reliability.

Depending on different aggregation modes, aggregation groups fall into three types:

manual, static LACP, and dynamic LACP. Depending on whether or not load sharing is

implemented, aggregation groups can be load-sharing or non-load-sharing aggregation

groups.

Note:

Up to 384 aggregation groups can be created in a system, where up to 64 load-sharing

aggregation groups can be created.

For the member ports in an aggregation group, their basic configuration must be the

same. The basic configuration includes STP, QoS, VLAN, port attributes and other

associated settings.

STP configuration, including STP status (enabled or disabled), link attribute

(point-to-point or non-point-to-point), STP priority, STP path cost, STP standard

packet format, maximum transmission speed, loop guard status, root guard status,

edge port or not.

QoS configuration, including traffic rate limiting, priority marking, default 802.1p

priority, bandwidth assurance, congestion avoidance, traffic redirection, traffic

statistics, and so on.

VLAN configuration, including permitted VLANs, and default VLAN ID.
