AX411 Access Point Wireless LAN Initial Software Configuration Overview

The procedures in this topic describe how to establish communication between the AX411 Access Point and the SRX Series Services Gateway that manages it. When this communication is established, the Status LED on the access point lights green, showing that the access point is being managed by the services gateway. Then the services gateway loads a default configuration onto the access point that establishes a basic wireless LAN.

Once you have established communication between the access point and the services gateway, you can perform advanced software configuration of the access point as described in the Junos OS WLAN Configuration and Administration Guide.

If one or more access points are connected to the built-in Ethernet ports on the services gateway other than ge-0/0/0, and the ports are in their factory default configuration, each access point will automatically obtain an IP address using DHCP, and the services gateway will deliver a default configuration to the access point. The Status LED on the access point will light green, showing that the access point is being managed by the services gateway. By default, the services gateway will accommodate up to two access points. You can connect and use more than two access points if you also install access point licenses on the services gateway.

For services gateways in the SRX200 line, the factory default settings establish a VLAN consisting of all of the built-in ports except 0/0 (interface ge-0/0/0). These ports all have a family setting of “ethernet-switching.” The VLAN has a logical interface that has an IP address and belongs to the Trust zone. DHCP is enabled for the VLAN. Access points connected to these ports operate in Layer 2 management mode by default.

For the SRX650 Services Gateway, the factory default settings establish a logical interface for each of the four built-in Ethernet ports except ge-0/0/0. Each logical interface has an IP address and belongs to the Trust zone. DHCP is enabled on each port. Access points connected to these ports operate in Layer 3 management mode by default.

For more information about access point Layer 2 and Layer 3 management modes, see the Junos OS WLAN Configuration and Administration Guide.

The easiest way to check whether the services gateway is properly configured to communicate with the access point is to perform the sequence of tasks described in Table 1. If at the end of this sequence the Status LED on the access point is steady green and you can detect the juniper-default wireless network with a laptop or other Wi-Fi device, the services gateway is properly configured.

The most important aspect of the services gateway configuration is that the access point must be able to obtain an IP address from the services gateway using DHCP. The access point must obtain an IP address using DHCP in order for the services gateway to manage the access point, even if the access point is configured to use a static IP address. The factory default configuration for services gateways in the SRX200 line enables DHCP for the logical interface of the VLAN to which all of the built-in ports except 0/0 (interface ge-0/0/0) belong. The factory default configuration for SRX650 Services Gateways enables DHCP on the logical interface for each of the built-in ports except 0/0.

If the ports of your services gateway are not in their factory default configurations, see AX411 Access Point Configuration Example: Layer 2 Mode (CLI) and AX411 Access Point Configuration Example: Layer 3 Mode (CLI) for examples of how you can configure the services gateway ports for access points in Layer 2 or Layer 3 operation.
