preemption
Enables pre-emption when no
uplinks are enforced. When
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

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.
Uplink Priority
When uplink priority is configured, the W-IAP tries to get a higher priority link every ten minutes even if the current
uplink is up. This does not affect the current uplink connection. If the higher uplink is usable, the W-IAP switches
over to that uplink. Preemption is enabled by default.
