This object controls the format of the RADIUS password attribute that is included in requests to the RADIUS server for authenticating non-EAP clients (MAC addresses). If the ipAddr(0) bit is set, the password attribute will contain the switch's IP address encoded as a string of four 3-digit 0-padded integers. For example, the encoding for the IP address 47.80.225.1 would be '047080225001'. If the macAddr(1) bit is set, the password attribute will contain the MAC address to be authenticated as a string of six 2-digit hex numbers. For example, the MAC address 00:08:01:0a:33:34 would be encoded as '0008010a3334'. If the portNumber(2) bit is set, the password attribute will contain the port number on which the MAC address was seen, encoded as a string of two 2-digit 0-padded integers. The first integer is the unit/slot number, and the second number is the port number on that unit/slot. For a standalone stackable unit, the unit/slot number will be 0. For example, the encoding for unit/port 1/23 would be '0123', and the encoding for port 7 on a standalone stackable unit would be '0007'. If the key(3) bit is set, the password attribute will contain a custom configured string of up to 32 characters in length. If padding(4) bit is set, the password will contain dots even if fields in the password are blank. For instance, IP and Key will be represented as IP...Key. If the bit is not set, there will be dots only to separate fields. IP and Key will be IP.Key, while IP, Mac, Port or Key alone will be as they are, with no dots. The fields in the password attribute will appear in the order of the bits defined in this object, i.e., IP addr, followed by MAC addr, followed by port number, and finally by the key. Fields are separated by a '.' character. The separators are present regardless of whether a field is present if padding is used. So, for example, if all four fields are present, the password attribute might contain: 047080225001.0008010a3334.0123.ERS4000isGreat If none of the three fields are present, the password attribute will be '...' with padding used, or '' with no padding.
