Extending Dictionary Files with JUNOSe Parameters for the Merit AAA Server
In addition to supporting standard RADIUS attributes, the JUNOSe router supports JUNOSe-specific attributes. These attributes must be introduced to the Merit AAA server. You must use the RADIUS attributes for both Merit AAA server-JUNOSe router integration and Merit AAA server-JUNOSe router-SRC integration. See the JUNOSe Broadband Access Configuration Guide for more information about the RADIUS attributes supported by the JUNOSe router.
If you use the Merit AAA server package that we supply, you do not need to extend the dictionary files, and you can proceed to the next section. If, however, you use another version of the Merit AAA server, you must extend the dictionary file.
In such a case, move to the configuration directory of the Merit AAA installation, and edit the dictionary file. Append the JUNOSe-specific attributes to the dictionary file in the following way:
- Access the directory in which you installed the Merit AAA installation.
cd /opt/UMC/radius- Open the radius.dct file.
- At the end of the file, add the JUNOSe attributes in the ERX RADIUS Dictionary file. To locate the ERX RADIUS Dictionary file, see the JUNOSe software documentation for the supported release on the Juniper Networks Web site at
http://www.juniper.net/techpubs/software/
The next step defines the JUNOSe router as the network access server (NAS) to be recognized by the Merit AAA server. This involves the extension of the vendor file, which is located in /opt/UMC/radius/etc.
The vendor file contains a list of zero or more vendor entries. Each vendor entry contains a vendor name and a vendor number. Each entry optionally contains an interim way of mapping external (with respect to the RADIUS server) attribute numbers to internal (with respect to the RADIUS server) vendor-specific attributes. This optional mapping is used on RADIUS requests and responses. The following lines must be added, where every line starting with the character "#" indicates a comment:
