2.Under UPLINK PRIORITY LIST, select the uplink, and 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.

Enabling uplink pre-emption

The following configuration conditions apply to uplink pre-emption:

Pre-emption can be enabled only when no uplink is enforced.

When pre-emption is disabled and the current uplink fails, the AP tries to find an available uplink based on the uplink priority configuration.

When pre-emption is enabled and if the current uplink is active, the AP periodically tries to use a higher priority uplink, and switches to a higher priority uplink even if the current uplink is active.

To enable uplink pre-emption:

1.Select Wireless Configuration > System > Uplink. The Uplink details are displayed.

2.Under MANAGEMENT, ensure that the ENFORCE UPLINK is set to None.

3.From PRE-EMPTION, select Enabled.

4.Click OK.

Switching uplinks based on internet availability

You can configure Cloud Network Manager to switch uplinks based on internet availability.

When the uplink switchover based on internet availability is enabled, the AP continuously sends ICMP packets to some well-known internet servers. If the request is timed out due to a bad uplink connection or uplink interface failure, and the internet is not reachable from the current uplink, the AP switches to a different connection.

To configure uplink switching:

1.Select Wireless Configuration > System > UPLINK. The Uplink details are displayed.

2.Under Management, configure:

INTERNET FAILOVER — To configure uplink switching based on Internet availability, perform the following steps:

a.Select Enabled from INTERNET FAILOVER.

b.Specify values for FAILOVER INTERNET PACKET SEND FREQUENCY, FAILOVER INTERNET PACKET LOST COUNT, and INTERNET CHECK COUNT,

c.Click OK.

Mobility and client management

This section provides the following information:

Layer-3 mobility overview

APs form a single Cloud Network Manager network when they are in the same Layer-2 (L2) domain. As the number of clients increase, multiple subnets are required to avoid broadcast overhead. In such a scenario, a client must be allowed to roam away from the Cloud Network Manager network to which it first connected (home network) to another network supporting the same WLAN access parameters (foreign network) and continue its existing sessions.
