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.
4.8.3 Configuring WLAN Assignment
Use the WLAN Assignment tab to assign WLANs and security schemes.
