Parameters • enable-Enables preemption on the port channel. • disable-Disables preemption on the port channel. Default Enabled Command Mode Port-channel INTERFACE Usage Information When you enable preemption, the fallback port election preempts the already elected fallback port and elects a new fallback port. The new port is elected based on the following events: • When a nonfallback port is configured with low priority. • When a low-priority port becomes operationally UP. • When a port with the least numbering is operationally UP. • If nondefault LACP port priority is configured on a port even though preemption is disabled, aport with the lowest priority is elected as fallback port, • The lacp fallback preemption disable command is not applicable on port priority events that you have configured or triggered.
