Configuring an IPSec Tunnel
An IPsec tunnel is configured to ensure that the data flow between the networks is encrypted. When
configured, the IPSec tunnel to the controller secures corporate data.
You can configure an IPSec tunnel from Virtual Controller using the Instant UI or CLI.
In the Instant UI
To configure a tunnel using the IPSec protocol:
1. Click the More > VPN link at the top right corner of the Instant UI. The Tunneling window is displayed.
2. Select Aruba IPSec from the Protocol drop-down list.
3. Enter the IP address or fully qualified domain name (FQDN) for the primary VPN/IPSec endpoint in the
Primary host field.
4. Enter the IP address or FQDN for the backup VPN/IPSec endpoint in the Backup host field. This entry is
optional. When you specify the primary and backup host details, the other fields are displayed.
5. Specify the following parameters. A sample configuration is shown in Figure 52.
a. To allow the VPN tunnel to switch back to the primary host when it becomes available again, select
Enabled from the Preemption drop-down list. This step is optional.
b. If Preemption is enabled, specify a value in seconds for Hold time. When preemption is enabled and
the primary host comes up, the VPNtunnel switches back to the primary host after the specified hold-
time. The default value for Hold time is 600 seconds.
c. To allow the W-IAP to create a backup VPN tunnel to the controller along with the primary tunnel, and
maintain both the primary and backup tunnels separately, select Enabled from the Fast failover drop-
down list. When fast failover is enabled and if the primary tunnel fails, the W-IAP can switch the data
stream to the backup tunnel. This reduces the total failover time to less than one minute.
d. To disconnect all wired and wireless users when the system switches during VPNtunnel transition from
primary to backup and backup to primary, set Reconnect user on failover to Enabled.
e. To configure an interval during which the wired and wireless users are disconnected during a VPN tunnel
switch, specify a value in seconds for Reconnect time on failover within a range of 30—900 seconds.
By default, the reconnection duration is set to 60 seconds.
f. Specify a value in seconds for Secs between test packets. Based on the configured frequency, the W-
IAP can verify if an active VPN connection is available. The default value is 5 seconds, which means that
the W-IAP sends one packet to the controller every 5 seconds.
g. Enter a value for Max allowed test packet loss, to define a number for lost packets, after which the
W-IAP can determine that the VPNconnection is unavailable. The default value is 2.
