NOTE

When multiple ports from the same server are connected to an ICX 6650, the port on the ICX 6650

connected to the PXE-capable port on the server is the port that must be configured to the force-up

state. The PXE-capable port varies from server to server.

Keep the following points in mind when configuring a port to a force-up state:

• A port can only be configured as the force-up port before the client is deployed.

• Only one port in an LACP link aggregation group can be configured as the force-up port. If you

configure multiple ports as force-up, this error message is displayed: Error: port portno is

already configured as force-up port.

• When a port is configured for force-up and the server boots for the first time, the port does not wait

for any LACPDU but immediately begin to forward packets.

• If the port receives an LACPDU, it bundles with other ports and forms a link aggregation group. The

server is operational.

• If the force-up port goes down while in a link aggregation group, the port continues to perform as a

normal LACP trunk, and the server remains operational, with some ports down.

• If the force-up port stops receiving LACPDU, the port ignores the time-out and remains operational.

To configure the LACP client in a force-up state, use the client-interface link-aggregation force-

up ethernet command at the Client level.

Syntax: [no] client-interface link-aggregation force-up ethernet unit/

slotnum/portnum

The following example shows the link aggregation information for a port

configured to a force-up state.
