DSI Signaling Server SGW Mode User Manual Issue 5

3.2.4 Installing Software Licenses

This section describes how additional licenses are installed on the Signaling Server. Each Signaling Server is

licensed to run specific components of the protocol stack. The STLCP command provides a printout that

shows which components are licensed on a particular unit. Each unit is uniquely identified by a unit identity

value, which is displayed as the UNITID parameter in the CNSYP command output.

The License File, purchased as described in this chapter, is a simple text file. The contents of the file are

similar to the following:

FEATURE SGW_U_G30 dialogic 1.000 permanent uncounted \

HOSTID=000e0de513c4 SIGN="00ED 17C4 1197 F91E E36F D5F5 9371 \

1600 2CC9 8AF4 82C9 3AF5 F1C6 9329 B5CD"

Normal operation of the license update procedure uses MML to update the system’s purchasable licenses with

the file taken directly from a Remote Data Center (RDC).

The procedure to install licenses from system start is as follows:

1. Rename the purchased license file to sgw.lic.

2. Establish an FTP session (see Section 4.9, “FTP Access” on page 30).

3. Set the FTP transfer mode to “ASCII”, since the license file is a text file.

4. Transfer the software license to the Signaling Gateway by typing the command “put sgw.lic sgw.lic”.

Note: The Signaling Gateway uses a case-sensitive file system. Therefore, it is necessary to specify

sgw.lic in lowercase.

5. Terminate the FTP session by entering “quit” or “bye”.

6. Establish an MML session and restart the unit by typing the following command:

MNRSI:RESTART=SOFT,SYSTYPE=SGW;

The machine then boots and completes the upgrade. Once the upgrade is complete, the machine is

accessible via MML.

7. Check the licenses using the STLCP command.

Note: If the licensing upgrade fails, the unit restores the previous licensing level.

3.2.5 License Update from Remote Data Center

The procedure to perform a license update from the a Remote Data Center (RDC) is as follows:

1. The user should enter:

CNUPI:DTYPE=LICENSE,RDC=<rdc id>,DIRECTORY=<subdirectory>;

to request that the license be updated from a RDC where the license file is stored in a subdirectory in the

ftproot.

2. Once you have confirmed that the license should be updated, the license file is transferred to the

Signaling Gateway without further interaction with the user. The unit indicates that the file has been

successfully transferred by displaying the “EXECUTED” response to the CNUPI command.

3. Establish an MML session and restart the unit by typing the following command:

MNRSI:RESTART=SOFT;

The machine then boots and completes the upgrade. Once the upgrade is complete, the machine is

accessible via MML.

4. Check the licenses using the STLCP command.
