Preparing The Network For Distributed Access Points - Enterasys RoamAbout RBT-8110 Installation Manual

Preparing the Network for Distributed Access Points

An AP that is not directly connected to a RoamAbout wireless switch is considered a Distributed
AP (DAP). RoamAbout APs are DAPs that require the following support in order to find a
RoamAbout wireless switch to configure and manage them:
• 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:
•
•
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.
•
•
• DNS—If the intermediate network between the RoamAbout wireless switch and DAP
includes one or more IP routers, do one of the following:
•
•
IP address
Default router (gateway) address
Domain name
DNS server address
Configure DHCP option 43 on the DHCP server (see above).
Create a wlan‐switch.mynetwork.com entry on the DNS server.
