Link Aggregation

7.2.9.1

Static Trunk

"Ling Aggregation" (also called "Trunking"), parallel link bundling) is the
grouping of physical ports into one logical ling with higher capacity. When
bundling ports, it can be more cost effective to use multiple lower-speed links
than to underutilize a high-speed, but expensive "Port Link".
However, the more ports you aggregate, the fewer available ports you have. A
"Trunk Group" is one logical link containing multiple ports. The switch supports
both static and dynamic "Link Aggregation".
"Link Aggregation"
In a well-planned network, only static "Link Aggregation" is recommended. This
ensures increased network stability and control over "Trunk Groups" on your
switch.
7.2.9.2

LACP

The switch supports static and dynamic (LACP) "Port Trunking" according to
IEEE 802.3ad. The IEEE 802.3ad standard describes LACP ("Link Aggregation
Control Protocol") for dynamic creation and management of "Trunk Groups".
When you enable "LACP Link Aggregation" on a port, the port can automatically
negotiate with the ports at the remote end of a link to establish "Trunk Groups".
LACP also allows port redundancy, i.e., if an operational port fails, then one of
the "standby" ports becomes operational without user intervention
The following should be noted:
• All ports must be connected peer-to-peer to the same ETHERNET switch
and configured for "LACP Trunking".
• LACP only works on full-duplex links.
• All ports in the same "Trunk Group" must have the same media type, speed,
duplex mode and settings for "Flow Control".
• Configure the "Trunk Groups" or LACPs before you connect to the
ETHERNET switch to prevent looping in the network topology.
