Add a Vendor-Specific Attribute (VSA) A Vendor Specific Attribute (VSA) is a RADIUS attribute defined for a specific vendor. You are able to add vendor-specific attributes to a vendor by clicking the vendor in the RADIUS dictionary list view and then clicking the Add VSA icon link. Each attribute has a name and a unique number specific to that vendor. Refer to your vendor's documentation for the attribute name, number and type settings to use. The attribute type can be one of:  Integer  String  Binary  IPv4 Address  Date/Time  IPv6 Address  IPv6 Prefix  Interface ID (8 octets)  Ascend Binary Filter Attribute numbers are normally small decimal numbers in the range 0-255. These may be entered in decimal, or in hexadecimal using the '0x' prefix. Certain vendors in the dictionary have support for larger attribute values. If you want the attribute to appear in the active session views and on RADIUS accounting reports, check the Visible in Active Sessions check box. This allows the attribute to be searched and filtered. Once the data has been entered, click the Create Attribute button to complete the creation. Click the Cancel button if you do not want to proceed with creating this vendor attribute. Amigopod 3.7 | Deployment Guide RADIUS Services | 75
