Summit WM-Series WLAN Switch and Altitude Access Point Software Version 1.0 User Guide

Port Type or Function
A new Summit WM-Series Switch is shipped from the factory with all its data ports set up as “Host
ports”, and support of management traffic disabled on all data ports. In the Summit WM-Series Switch
Configuration – IP Addresses screen, you can redefine the data ports to function as one of three types:
Host Port
Use “Host Port” for connecting Altitude APs, with no dynamic routing. A “Host Port” has dynamic
routing disabled to ensure that the port does not participate in dynamic routing operations, such as
OSPF, to advertise the availability of WM-ADs hosted by the Summit WM-Series Switch. “Host
Ports” may still be used as the target for static route definitions.
Third-Party AP Port
Define as3rd-Party AP a port to which you will connect third-party access points. No more than
one port can be configured for third-party APs.
Selecting this option prepares the port to support a third-party AP setup that allows the mapping of
an WM-AD to the physical port. The WM-AD settings then permit the definition of policy, such as
filters and Captive Portal, that manage the traffic flow for wireless users connected to these access
points.
The third-party access points must be operating as layer-2 bridges. The “third-party AP” WM-AD is
isolated from the rest of the network. The Summit WM-Series Switch assumes control over the layer-
3 functions such as DHCP.
Altitude APs must not be attached to a “3rd-Party AP” port.
Router Port
Define asRouter Port a port that you wish to connect to an upstream next-hop router in the
network. Dynamic routing protocol such as OSPF can be turned on for this port type.
Altitude APs can be attached to aRouter port. The Summit WM-Series Switch will create a virtual
WM-AD port and handle wireless device traffic in the same manner as a “Host port”. Third-party
access points must not be directly connected to a “Router” port.
There is a fourth port type that is not configurable in the user interface:
WM Access Domain Services (WM-AD) interface
An WM-AD port is a virtual port created automatically on the Summit WM-Series Switch when a
new WM-AD is defined. The WM-AD port becomes the default gateway for wireless devices on this
WM-AD. No Altitude APs can be associated with an WM-AD port and no routing is permitted on
this port.
