Figure 9 Fn Switch on WXR100

5Because the Fn switch was pressed while the switch was starting, the WXR100 configures the following items, to enable itself to contact 3WXM Services:

„Ports 1 and 2 in the default VLAN (VLAN 1)

„DHCP client on VLAN 1 enabled

6The WXR100 uses the DHCP client to obtain an IP configuration from a local DHCP server. After obtaining an IP configuration, the switch sends a DNS query for the IP address of well-known hostname wlan-config-srv.

7DNS replies with the IP address of the host where 3WXM Services are installed. The WXR100 sends a configuration request to 3WXM Services.

83WXM receives the configuration request, and looks in the currently selected network plan for a WXR100 configuration with the same serial number as the one in the configuration request.

„If the network plan contains a configuration with a matching serial number, 3WXM deploys the configuration to the switch. (See “Preconfiguring a Switch in 3WXM”.)

„If the network plan does not have a configuration with a matching serial number, one of the following occurs:

„If the Auto-Config IP Subnet Matching is enabled and other requirements are met, 3WXM can give the configuration to another switch with a different serial number, if the switch is the same model and is in the same IP subnet. (See “Replacing a Switch and Reusing its Configuration” on page 342 for more information.)
