Concept Guide

2. Under Uplink Management, configure the following parameters:
l VPN failover timeout—To configure uplink switching based on VPNstatus, specify the duration to
wait for an uplink switch. The default duration is set to 180 seconds.
l Internet failoverTo configure uplink switching based on Internet availability, perform the following
steps:
a. Select Enabled from the Internet failover drop-down list.
b. Specify the required values for the following fields:
n Max allowed test packet loss The maximum number of ICMP test packets that are
allowed to be lost to determine if the W-IAP must switch to a different uplink
connection. You can specify a value within the range of 1—1000.
n Secs between test packets The frequency at which ICMP test packets are sent.You
can specify a value within the range of 1—3600 seconds.
n Internet check time Internet check timeout is the duration for the test packet
timeout. You can specify a value within the range of 0—3600 seconds and the default
value is 10 seconds.
c. Click OK.
When Internet failover is enabled, the W-IAP ignores the VPN status, although uplink switching based on VPN
status is enabled.
In the CLI
To enable uplink switching based on VPN status:
(Instant AP)(config)# uplink
(Instant AP)(uplink)# failover-vpn-timeout <seconds>
(Instant AP)(uplink)# end
(Instant AP)# commit apply
To enable uplink switching based on Internet availability:
(Instant AP)(config)# uplink
(Instant AP)(uplink)# failover-internet
(Instant AP)(uplink)# failover-internet-pkt-lost-cnt <count>
(Instant AP)(uplink)# failover-internet-pkt-send-freq <frequency>
(Instant AP)(uplink)# end
(Instant AP)# commit apply
