Once the Network Location Register (NLR) package has been successfully installed, it must be configured to make it fully functional. Basic configuration steps include adding subscribers and groups to the RFSS and defining home ranges for those subscribers and groups that are homed at that RFSS. This chapter describes how to configure the Web interface and the Network Interface Function (NIF), and it includes the following topics:
•Network Interface Function
The Web interface has configuration parameters that should be modified after installation. To configure the Web Interface, perform the following procedure:
Step 1 Open the file, located at /home/NlrUser/WebInterface/include/config.inc.php.
Step 2 Modify the entry "THIS_NLR", so that it represents the RFSS that this NLR is part of. The format for this entry is the same as for other /etc/hosts entries, for example:
The identifiers are all hexadecimal numbers which are zero padded and are of the following fixed lengths:
•Rfss_Id: 2 hexadecimal characters (that is, 8 bits).
•System_Id: 3 hexadecimal characters (that is, 12 bits).
•Wacn_Id: 5 hexadecimal characters (that is, 20 bits).
If the NLR is co-hosted on the same machine as the RNC and the hostname of the RNC is of the above format, then the commented entry including "uname -n" may be used to set "THIS_NLR" identity instead.
Network Interface Function
For versions 2.03.000 and later, additional steps must be performed to allow communication between the NLR and RNC. To configure the NIF, perform the following procedure:
Step 1 Allocate an IP address to the NIF so that the NIF can communicate with the RNC.
The IP address chosen must not be in use by any other core network process. If the NLR is co- hosted on the same machine as the RNC, then the new IP address can either be added on the same interface or on a separate interface if the host machine has this capability. The use of localhost or 127.0.0.1 for this address is not recommended as these addresses are not externally visible.
Step 2 Assign a valid SUID to the NIF, so that it can communicate with the NLR.
Typically, this will consist of the home WACN and SYSTEM identifiers, along with the last octet of the NIF IP address as the unitId, converted to ISSI (zero-padded hexadecimal) format.
Step 3 Open the config.inc.php file, located at /home/NlrUser/WebInterface/include/config.inc.php and do the following:
•Enter the NIF SUID and IP address values.
•Add a unit subscriber via the NLR web interface matching the NIF_SUID you have specified. For more information about adding a subscriber, see the "Adding a Single Subscriber" section and the "Adding Multiple Subscribers" section.
Step 4 Open the Nif.config file, located at /home/NlrUser/bin/Nif/Nif.config and do the following:
•Edit the site details in the fields NIF.SiteId, NIF.RfssId, NIF.SystemId and NIF.WacnId to match the details in the /etc/hosts file.
•In the SIP.Local IPAddress field, enter the same IP address used in the config.inc.php file for the NIF_ADDRESS.
Step 5 Edit /etc/hosts on the NIF host machine, adding an entry for the RNC, so that this NIF can communicate with the RNC. For more information, see the Cisco RFSS Network Controller Series User Guide.
If the NLR is co-hosted on the same machine as the RNC, there should already be an entry for the RNC host.
Step 6 Edit /etc/hosts on the RNC host machine, adding an entry for the NIF so the RNC can communicate with this NIF. For more information, see the Cisco RFSS Network Controller Series User Guide.
Step 7 Restart the monit service. To do this, type:
There should be an entry for the "NifService" running.
