Chapter 16 Link Aggregation

You must connect all ports point-to-point to the same Ethernet switch and configure the ports 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 flow control settings.

Configure trunk groups or LACP before you connect the Ethernet switch to avoid causing network topology loops.

16.2.1 Link Aggregation ID

LACP aggregation ID consists of the following information2:

16.3 Static Trunking Example

This example shows you how to create a static port trunk group for ports 2-5.

1Make your physical connections - make sure that the ports that you want to belong to the trunk group are connected to the same destination. The following figure shows ports 2-5 on switch A connected to switch B.

Figure 49 Trunking Example - Physical Connections

2.Port Priority and Port Number are 0 as it is the aggregator ID for the trunk group, not the individual port.
