4.12 Trunking Configuration

The Port Trunking Configuration is used to configure the settings of Link Aggregation. You
can bundle more than one port with the same speed, full duplex and the same MAC to be a
single logical port, thus the logical port aggregates the bandwidth of these ports. This
means you can apply your current Ethernet equipments to build the bandwidth aggregation.
For example, if there are three Fast Ethernet ports aggregated in a logical port, then this
logical port has bandwidth three times as high as a single Fast Ethernet port has.

The switch supports two kinds of port trunking methods:

LACP:

Ports using Link Aggregation Control Protocol (according to IEEE 802.3ad
specification)

as their trunking method can choose their unique LACP GroupID

(1~8) to form a logic “trunked port”. The benefit of using LACP is that a port makes
an agreement with its peer port before it becomes a ready member of a “trunk
group” (also called aggregator). LACP is safer than the other trunking method -
static trunk.

The switch LACP does not support the followings:

Link Aggregation across switches

Aggregation with non-IEEE 802.3 MAC link

Operating in half-duplex mode

Aggregate the ports with different data rates

Static Trunk:

Ports using Static Trunk as their trunk method can choose their unique Static
