force-up ethernet
The member ports of a dynamic LAG are logically operational only if the dynamic LAG is operating.
Dynamic LAG configuration mode
The
no form of the command causes the specified port to be logically operational only when
the dynamic LAG is operating.
When the dynamic LAG is not operational, the port goes to "force-up" mode. In this mode, the port is logically operational, which enables a PXE-capable host to boot from the network using this port. Once the host successfully boots from the network, the dynamic LAG can connect the host to the network with the LAG link. Even if the dynamic LAG fails later, this port is brought back to "force-up" mode and remains logically operational.
A port that is in "force-up" mode has the operational status ("Ope" ) of "Frc". Use
the
show lag command to display the operational status.
If any port in a dynamic LAG receives an LACPDU, the port in force-up mode leaves force-mode and becomes a member port in the dynamic LAG.
