Configuring the Shared Licensing Server

This section describes how to configure the ASA to be a shared licensing server.
Prerequisites
The server must have a shared licensing server key.
Detailed Steps
Step1 Choose the Configuration > Device Management > Licenses > Shared SSL VPN Licenses pane.
Step2 In the Shared Secret field, enter the shared secret as a string between 4 and 128 ASCII characters.
Any participant with this secret can use the license server.
Step3 (Optional) In the TCP IP Port field, enter the port on which the server listens for SSL connections from
participants, between 1 and 65535.
The default is TCP port 50554.
Step4 (Optional) In the Refresh interval field, enter the refresh interval between 10 and 300 seconds.
This value is provided to participants to set how often they should communicate with the server. The
default is 30 seconds.
Step5 In the Interfaces that serve shared licenses area, check the Shares Licenses check box for any interfaces
on which participants contact the server.
Step6 (Optional) To identify a backup server, in the Optional backup shared SSL VPN license server area:
a. In the Backup server IP address field, enter the backup server IP address.
b. In the Primary backup server serial number field, enter the backup server serial number.
c. If the backup server is part of a failover pair, identify the standby unit serial number in the Secondary
backup server serial number field.
