preemption
Enables pre-emption when no

enabled, if the current uplink is
active, the W-IAP periodically
tries to use a higher priority
uplink, and switches to a higher
priority uplink even if the current
uplink is active.
— Disabled
uplink-priority
{cellular <priority>|ethernet <priority>|
[port <Interface-number> <priority>]|
wifi <priority>}

Usage Guidelines
Use this command to set preferences for enforcing uplinks or enabling preemption and to configure uplink
switchover.
Enforcing uplinks
The following configuration conditions apply to the uplink enforcement:
l When an uplink is enforced, the W-IAP uses the specified uplink regardless of uplink preemption
configuration and the current uplink status.
l When an uplink is enforced and multiple Ethernet ports are configured and uplink is enabled on the wired
profiles, the W-IAP tries to find an alternate Ethernet link based on the priority configured.
l When no uplink is enforced and preemption is not enabled, and if the current uplink fails, the W-IAP tries to
find an available uplink based on the priority configured.
Uplink Preemption
When no uplink is enforced and preemption is enabled, and if the current uplink fails, the W-IAP tries to find an
available uplink based on in the priority configured. If current uplink is active, the W-IAP periodically tries to use
a higher priority uplink and switches to the higher priority uplink even if the current uplink is active.
