Attribute 26 (Vender-Specific) defined in thisprotocol allows a device vendor to extend RADIUS to implement functions that are notdefined in standard RADIUS.Figure 1-4 depicts the format of attribute 26. The Vendor-ID field used to identify avendor occupies four bytes, where the first byte is 0, and the other three bytes aredefined in RFC 1700. Here, the vendor can encapsulate multiple customizedsub-attributes (containing vendor-specific Type, Length and Value) to implement aRADIUS extension.Type……Length07Vendor-ID7 15 31Vendor-ID Type (specified) Length (specified)Specified attribute value……Figure 1-4 Vendor-specific attribute format
