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.
