4.8.2 Configuring Layer 3 Access Port Adoption

The configuration activity required for adopting access ports in a layer 3 environment is unique. In a layer 3 environment, switch discovery is attempted in the following ways:

•On the local VLAN

•Through the DHCP Server

Initially, the access port attempts to find its wireless switch by broadcasting a Hello packet on its local VLAN. During this activity:

1.All switches on the VLAN that receive this Hello packet respond with a parent packet.

2.If no response is received, the access port attempts to discover its switch by first obtaining an IP address from a DHCP (or DNS) server and checking the options field within the DHCP response.

The options field (Option 189) contains a list of switch IP addresses available for the access port.

3.The system administrator now programs these options into the DHCP server.

4.If the access port finds the list, it sends a unidirectional Hello packet (encapsulated in a UDP/IP frame) to each switch on the list.

5.Each switch that receives such a packet responds with a Parent response.
