WLAN Overview
The wireless local area network (WLAN) system supported in this Junos OS Release consists of an SRX Series Services Gateway and one or more AX411 Series WLAN Access Points that are centrally managed by the SRX Series device. The access points are connected to the ports on the SRX Series device and can relay data between the wired and wireless network.
A WLAN allows wireless clients to communicate with each other and access the wired network. Wireless clients can be laptop or desktop computers, personal digital assistants (PDAs), or any other device equipped with a Wi-Fi adapter and supporting drivers. When a wireless client starts up, it searches for beacon frames that originate from access points to determine the service the access points provide. Upon completing predefined authentication with an access point, the client is connected or associated with the access point and can access the network. Depending upon the type of authentication configured, the access point might need to communicate with a RADIUS server to validate or authenticate the client.
The AX411 Access Point can only be managed from an SRX210, SRX240, or SRX650 Services Gateway with the appropriate access point licenses installed. Up to 32 access points can be connected to an SRX Series Services Gateway. Multiple access points can be connected to a single port on the SRX Series device through an external switch or hub.
 | Note: The SRX Series device can manage only the AX411 Access Point and not any other vendors’ access points. |
| Note: On all branch SRX Series devices, managing AX411 WLAN Access Points through a Layer 3 Aggregated Ethernet (ae) interface is not supported. |
| Note: On SRX210, SRX240, and SRX650 devices, you can configure and manage a maximum of four access points. |
The Juniper Networks WLAN provides security policies, AAA, and other security features for wireless access. Configuration and management of the AX411 Access Point is through either the Junos OS CLI or J-Web interface on the SRX Series Services Gateway. You can also use the Network and Security Manager (NSM) to configure and manage the access point through the SRX Series device. Access point logs are maintained on the SRX Series Services Gateway and upgrades of the access point software are performed from the SRX Series device.
