l 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 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. You can enforce a specific uplink on a W-IAP by using the Instant UI or CLI. In the Instant UI To enforce an uplink: 1. Click the System > show advanced settings > Uplink. The Uplink tab contents are displayed. 2. Under Uplink Management, select the type of uplink from the Enforce Uplink drop-down list. If Ethernet uplink is selected, the Port field is displayed. 3. Specify the Ethernet interface port number. 4. Click OK. The selected uplink is enforced on the W-IAP. In the CLI To enforce an uplink: (Instant AP)(config)# uplink (Instant AP)(uplink)# enforce {cellular|ethernet|wifi|none} (Instant AP)(uplink)# end (Instant AP)# commit apply Setting an Uplink Priority You can set an uplink priority by using the 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 Priority List, select the uplink, and click the icons at the bottom of the Uplink Priority List section, to increase or decrease the priority. By default, the Eth0 uplink is set as a high priority uplink. 3. Click OK. The selected uplink is prioritized over other uplinks. In the CLI To set an uplink priority: (Instant AP)(config)# uplink (Instant AP)(uplink)# uplink-priority {cellular | ethernet |[port ]|wifi } (Instant AP)(uplink)# end (Instant AP)# commit apply For example, to set a priority for Ethernet uplink: (Instant AP)(uplink)# uplink-priority ethernet port 0 1 (Instant AP)(uplink)# end (Instant AP)# commit apply 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 W-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 W-IAP periodically tries to use a higher priority uplink, and switches to a higher priority uplink even if the current uplink is active.

3. Specify the Ethernet interface port number.
4. Click
OK
. The selected uplink is enforced on the W-IAP.
In the CLI
To enforce an uplink:
(Instant AP)(config)# uplink
(Instant AP)(uplink)# enforce {cellular|ethernet|wifi|none}
(Instant AP)(uplink)# end
(Instant AP)# commit apply
Setting an Uplink Priority

3. Click
OK
. The selected uplink is prioritized over other uplinks.
In the CLI
To set an uplink priority:
(Instant AP)(config)# uplink
(Instant AP)(uplink)# uplink-priority {cellular <priority> | ethernet <priority>|[port
<Interface-number> <priority>]|wifi <priority>}
(Instant AP)(uplink)# end
(Instant AP)# commit apply
For example, to set a priority for Ethernet uplink:
(Instant AP)(uplink)# uplink-priority ethernet port 0 1
(Instant AP)(uplink)# end
(Instant AP)# commit apply
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 W-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 W-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.
