Overview

Reply Attributes are configuration parameters that the RADIUS server sends back to the Network Access Server (NAS) in response to an authentication request. These attributes allow the admin to identify how the network is established, determine what level of access is granted to a user, or configure reply attributes to assign VLANs based on user groups, ensuring network segmentation and access control.

VLAN (Virtual Local Area Network) tagging is a method of adding a unique tag to various networks to indicate which VLAN they belong to. It can help in managing traffic by segmenting users into various groups without the need for physically separate networks.

For example, a company has two SSIDs, namely Corporate SSID and Guest SSID. Employees are required to connect to the Corporate SSID and are placed in VLAN 5, while the guests are allowed to connect to the Guest SSID and are placed in VLAN 10. When the employees connect to the Wi-Fi network using their credentials, the RADIUS server authenticates the user and sends a reply attribute specifying VLAN 5. When the guests connect to the network via a different protocol, the reply attribute specifies VLAN 5. This way, the admin can ensure that the employees in VLAN 5 have access to the internal resources, and the guests in VLAN 10 only have access to the internet. Here, the user's traffic is routed to the appropriate segment, and they are granted access only to their allowed resources.
