When you aggregate ports, the ports and LAG must fulfill
the following conditions:
• All ports within a LAG must be the same media/
format type.
• A VLAN is not configured on the port.
• The port is not assigned to another LAG.
• The Auto-negotiation mode is not configured on
the port.
• The port is in full-duplex mode.
• All ports in the LAG have the same ingress filter
ing and tagged modes.
• All ports in the LAG have the same back pressure
and flow control modes.
• All ports in the LAG have the same priority.
• All ports in the LAG have the same transceiver
type.
•Ports can be configured as LACP ports only if the
ports are not part of a previously configured LAG.
LACP is a dynamic protocol which helps to automate
the configuration and maintenance of LAG's. The main
purpose of LACP is to automatically configure individual
links to an aggregate bundle, while adding new links and
helping to recover from link failures if the need arises.
LACP can monitor to verify if all the links are connected
to the authorized group. LACP is a standard in comput-
er networking, hence LACP should be enabled on the
Switch's trunk ports initially in order for both the partic-
ipating Switches/devices that support the standard, to
use it.
