Preparing the Network for Distributed Access Points

An AP that is not directly connected to a RoamAbout wireless switch is considered a Distributed AP. Distributed APs require the following support in order to find a RoamAbout wireless switch to configure and manage the AP:

•Power—Power over Ethernet (PoE) must be provided on one of the Ethernet connections to the AP. Use a PoE injection device that has been tested by Enterasys Networks. Providing PoE on both of the Ethernet connections allows for redundant PoE.

•DHCP—A Distributed AP uses IP for communication, and relies on DHCP to obtain IP parameters. Therefore, DHCP services must be available on the subnet that the AP is connected to. DHCP must provide the following parameters to the AP:

–IP address

–Gateway address

The DHCP server might also need to supply the following DNS parameters, unless the RoamAbout wireless switch is in the same subnet as the APs, or DHCP option 43 is used to supply a list of RoamAbout wireless switch IP addresses or hostnames in the DHCP message.

–Domain name

–DNS server address

•DNS—If the intermediate network between the RoamAbout wireless switch and Distributed AP includes one or more IP routers, do one of the following:

–Configure DHCP option 43 on the DHCP server (see above).

–Create a wlan‐switch.mynetwork.com entry on the DNS server.
