For RADIUS authentication of a NEAP host MAC address, the switch generates a <user name, password> pair as described in the following list:
The user name is the NEAP MAC address in string format.
The password is a string that combines the switch IP address, MAC address, port number and user-configurable key string. If padding option is enabled, the system will specify a dot(.) for every missing parameter. IP address is represented by three decimal characters per octet.
Important
Use the following Global Configuration examples to select a password format that combines one or more of these three elements:
Padding enabled , password = 010010011253..05. (when the switch IP address and port are used).
Padding enabled, password = 010010011253… (when only the switch IP address is used).
No padding (default option). Password = 000011220001 (when only the user‘s MAC address is used).
switch IP address = 192.0.2.5 non-EAP host MAC address = 00 C0 C1 C2 C3 C4 port = 25 Key-String = abcdef
user name = 00C0C1C2C3C4
password = 010010011253.00C0C1C2C3C4.25.abcdef
