Enabling Uplink Preemption
The following configuration conditions apply to uplink preemption:
l Preemption can be enabled only when no uplink is enforced.
l When preemption is disabled and the current uplink goes down, the IAP tries to find an available uplink based on
the uplink priority configuration.
l When preemption is enabled and if the current uplink is active, the IAP periodically tries to use a higher priority
uplink, and switches to a higher priority uplink even if the current uplink is active.
You can enable uplink preemption using Instant UI or CLI.
In the Instant UI
1. Click the System > show advanced settings > Uplink. The Uplink tab contents are displayed.
2. Under Uplink Management, ensure that the Enforce Uplink is set to none.
3. Select Enabled from the Pre-emption drop-down list.
4. Click OK.
In the CLI
To enable uplink preemption:
(Instant AP)(config)# uplink
(Instant AP)(uplink)# preemption
