Radius Client For Mac

  

O radius — Use RADIUS without EAP encapsulation for the traffic between the switch (RADIUS client) and the RADIUS server, which authenticates a MAC-based supplicant. Groupsize — Number of ASCII characters between delimiters of the MAC address sent as a user name. The option are 1, 2, 4, or 12 ASCII characters between delimiters. MAC authentication with RADIUS Server provides facility to manage multiple APs from centralized database. User Manager is a RADIUS Application developed by MikroTik team and can be used to manage PPPoE, Hotspot, DHCP and Wireless user easily. How to install User Manager RADIUS Server with basic configuration was discussed in my previous article. MAC address format within Radius authentication from WLC I have a client that is binding their DHCP IP addresses to MAC addresses for each user for security reasons. They have an existing Autonomous environment and are in the process of replacing it with a lightweight solution. The switch (RADIUS client) sends a RADIUS Access-Request to the RADIUS server containing the username and password of the connecting device. The username and password combination is always the MAC address of the connecting device, lower case without delimiting characters. The wireless lan clients are windows and non windows devices such as laptops, desktops and handhelds. So the idea is to implement NPS and to configure the Radius server creating a policy just for filtering the mac address of the device. Is this possible using NPS? How can i specify the Mac address list of all devices?

When you enable secondary authorization on your network, a wireless user first authenticates on the wireless network, and then the device used to connect to the network is authenticated to determine whether it is an authorized device.

You can enforce device authorization through Google Device Authorization, or RADIUS MAC Authorization. For more information about Google Device Authorization, see Google Device Authorization.

You can use RADIUS MAC Authentication to allow only authorized devices to connect to your wireless network. When a client associates to an SSID with RADIUS MAC Authentication enabled:

  1. User authentication is initiated based on the security settings configured for the SSID. For example, the user could authentication with WPA2 with PSK.
  2. After the user successfully authenticates, the AP authenticates the MAC address of the connecting client with a RADIUS server.
  3. If the MAC authentication is successful, the client device is allowed to access the wireless network.
  4. If the MAC authentication fails, you can configure the AP device to take one of these actions:
  • Disconnect the client device because it is not authorized.
  • Assign a role to the user from the role profiles defined in Configuration > Device Configuration > Role Profiles. For example, you can prevent unauthorized devices from accessing certain VLANs.
  • Assign the SSID Profile to the client device. For example, you can redirect the client to a portal defined on the SSID. The portal can provide information about why access was denied or provide instructions for self-registration.
  • On their first authentication attempt, users are redirected to the portal configured on the SSID Profile. The RADIUS server can register the client MAC addresses of users that successfully log in to the portal.
  • For all subsequent attempts by these clients, the RADIUS server can authenticate their MAC addresses and assign a role to the clients. You can select this role using the Select Role for Successful Clients drop-down list.

The MAC addresses defined on your RADIUS server must all be in lower case format. For example: 00:aa:11:bb:22:cc.

Configure RADIUS MAC Authentication

To configure RADIUS MAC Authentication:

  1. Select Configuration > Device Configuration > SSID Profiles.
  2. Select an SSID Profile, or create a new SSID Profile.
  3. Expand the Security section.
  4. Set the Security Mode for the SSID.
  5. Select the Secondary Authentication check box.
  6. Select RADIUS MAC Authentication.
  7. Select an action to take if the client authorization fails: Disconnect or Assign Role.
  8. If you select Assign Role, from the Select Role drop-down list, select a role profile. Only role profiles defined in Configuration > Device Configuration > Role Profiles are listed here. For more information, see Role Based Control.
  9. Save the SSID configuration.

Description

Called Station ID

A free-form text parameter that the AP passes to the RADIUS server during the authentication or accounting process as the standard RADIUS parameter, Called-Station-Id. You can use one or more of the special format specifiers, %m, %n, %l or %s, to represent the called station ID. The AP replaces %m with the Ethernet MAC address of the AP. The AP replaces %s with the SSID. The AP replaces %l with the location tag. The AP replaces %n with the device name. You can repeat the format specifiers. You can enter text instead of using the format specifiers.
Note: If the length of this parameter exceeds 255 characters, the AP uses only the first 255 characters.

NAS ID

This parameter is used when a network access server (NAS) serves as a single point to access network resources. Generally, a NAS supports hundreds of simultaneous users. When a RADIUS client connects to a NAS, the NAS sends access request packets to the RADIUS server. /mac-os-1076-dmg.html. These packets must contain either the NAS IP address or the NAS identifier. The RADIUS server uses the NAS ID or the NAS-Identifier to authenticate RADIUS clients.
You can specify a string for the NAS ID. You can use one or more of the special format specifiers, '%m, %n, %l and/or %s, to represent the NAS ID. The AP replaces %m with the Ethernet MAC address of the AP. The AP replaces %s with the SSID. The AP replaces %l with the location tag. The AP replaces %n with the device name. You can repeat the format specifiers.
The default value of NAS ID is %m-%s. The NAS ID corresponds to the NAS-Identifier attribute on the RADIUS server. The attribute ID for the NAS-Identifier RADIUS attribute is 32.
Make sure that the NAS ID you specify is not the same as the shared secret configured for the RADIUS server in the RADIUS Authentication section.
Note: The AP uses the first 255 characters if the length of this parameter exceeds 255 characters because the total permissible length of this field is 255 characters.
