1.1 Overview

1.1.1 Introduction to Link Aggregation

Link aggregation means aggregating several ports together to implement the
outgoing/incoming load sharing among the member ports and to enhance the
connection reliability.
In terms of load sharing, link aggregation may be load-sharing aggregation and
non-load-sharing aggregation.
Note:
Currently, the S3100 series only supports manually-configured aggregation groups.
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 not), STP priority, maximum transmission speed, loop prevention
status, root protection status, edge port or not.
QoS configuration, including traffic 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.
Port attribute configuration, including port rate, duplex mode, and link type (Trunk,
Hybrid or Access).
The S3100 series supports up to three load-sharing aggregation groups, with two FE
(Fast Ethernet) groups and one GE (Gigabit Ethernet) group.
