Configuring a Tunnel from an AP to a Mobility Controller
19.2.1
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 the VC using the SCALANCE W UI or the CLI.
In the SCALANCE W UI
To configure a tunnel for IPsec protocol:
1.
Click the More > VPN link in the SCALANCE W 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 text box.
4.
Enter the IP address or FQDN for the backup VPN/IPsec endpoint in the Backup host text
box. This entry is optional. When you specify the primary and backup host details, the
other details are displayed.
5.
Specify the following parameters. A sample configuration is shown in Figure
IPsec
Configuration
.
–
To allow the VPN tunnel to switch back to the primary host when it becomes available
again, selectEnabled from the Preemption drop-down list. This step is optional.
–
If Preemption is enabled, specify a value in seconds for Hold time. When preemption
is enabled and the primary host comes up, the VPN tunnel switches back to the
primary host after the specified hold- time. The default value for Hold time is 600
seconds.
–
To allow the AP 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 AP can switch the data stream to the backup tunnel. This reduces the
total failover time to less than one minute.
