In the CLI

To set an uplink priority:

(Instant Access Point)(config)# uplink

(Instant Access Point)(uplink)# uplink-priority {cellular <priority> | ethernet <priority>|[po

rt <Interface-number> <priority>]|wifi <priority>}

(Instant Access Point)(uplink)# end

(Instant Access Point)# commit apply

For example, to set a priority for Ethernet uplink:

(Instant Access Point)(uplink)# uplink-priority ethernet port 0 1

(Instant Access Point)(uplink)# end

(Instant Access Point)# 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 OAW-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 OAW-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 AOS-W Instant UI or CLI.

In the AOS-W 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 Access Point)(config)# uplink

(Instant Access Point)(uplink)# preemption

(Instant Access Point)(uplink)# end

(Instant Access Point)# commit apply

Switching Uplinks Based on VPN and Internet Availability

The default priority for uplink switchover is Ethernet and then 3G/4G. The OAW-IAP can switch to the lower priority

uplink if the current uplink is down.

Switching Uplinks Based on VPN Status

AOS-W Instant supports switching uplinks based on the VPN status when deploying multiple uplinks (Ethernet,

3G/4G, and Wi-Fi). When VPN is used with multiple backhaul options, the OAW-IAP switches to an uplink

connection based on the VPN connection status, instead of only using the Ethernet or the physical backhaul link.

The following configuration conditions apply to uplink switching:

l If the current uplink is Ethernet and the VPN connection is down, the OAW-IAP tries to reconnect to VPN. The

retry time depends on the fast failover configuration and the primary or backup VPN tunnel. If this fails, the OAW-

IAP waits for the VPN failover timeout and selects a different uplink such as 3G/4G or Wi-Fi.
