SECTION 2 " Features and Functional Overview

Configuration of individual radio options and the WLIF wireless access point configuration are discussed in Section 4, “Configuration.”

OWL/IP Port

The OWL/IP port is a logical port used in installations where the wireless infrastructure is required to operate across multiple IP subnets; that is, in installations where IP routers are used.

The OWL/IP port is an advanced capability that allows stations supporting IP and nonroutable protocols such as NNL (used in some terminal emulation installations) to roam without losing connectivity when a wireless LAN installation must extend over multiple IP subnets. In some cases, OWL/IP may also provide connectivity in larger, routed networks when roaming between IP subnets is not required, but where it is desirable to configure a single wireless network across router boundaries.

OWL/IP uses General Router Encapsulation (GRE), a registered protocol from the TCP/IP protocol suite. GRE allows frames destined for stations on a different IP subnet to be encapsulated with an IP address that passes transparently through routers. Encapsulation is also sometimes referred to as tunneling.

To simplify configuration, OWL/IP functionality is treated as an additional port within the access point architecture. It is a logical port in that there is no physical radio or wired LAN port associated with OWL/IP.

Encapsulated frames may be sent through any of the three physical ports. Access points separated by one or more routers may be thought of as originating and receiving nodes on the two sides of a tunnel that is established through the router.
