3G/4G Switch Network
Uplink Switchover
The default priority for uplink switchover is Ethernet and then 3G/4G. The IAP has the ability to switch to the
lower priority uplink if the current uplink is down.
Uplink Switching based on VPN Status
Instant supports switching uplinks based on the VPN status when deploying mixed uplinks (Eth0, 3G/4G). When
VPN is used with multiple backhaul options, the IAP switches to an uplink connection based on the VPN
connection status instead of only using Eth0, the physical backhaul link. The behavior of the uplink switching is
described as follows:
If the current uplink is Eth0, this uplink is used until the VPN connection is down. When the VPN
connection is down at which point a different uplink (3G) is selected.
If the current uplink is 3G, and Eth0 has a physical link, the IAP periodically suspends user traffic to try and
connect to the VPN on the Eth0. If the IAP succeeds, then the IAP switches to Eth0. If the IAP does not
succeed, then the IAP restores the VPN connection to the current uplink.
Uplink Preemption
With this feature, the 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 IAP switches over to that uplink.
Pre-emption is enabled by default and the user can disable it by configuration.
Uplink Preference
Select the type of uplink from the
uplink preference
drop-down list under
Management
. To use a 3G/4G uplink,
select
3G/4G
from the
Uplink preference
drop-down list.
NOTE:
IAP reboot is not required for uplink swtichover process.
NOTE:
If VPN is configured, IAP monitors the VPN status, once VPN status is down for 3 minutes, the uplink switches over (if low
priority uplink is detected, and the uplink preference is none).
NOTE:
This feature is automatically enabled when a VPN is configured in the IAP.
