VLAN ID parameter
You can define a specific VLAN tag to be applied to a particular interface. All packets associated with
that port will be tagged with the corresponding VLAN. This allows the Summit WM Controller to
directly attach to a VLAN network without the need to remove VLAN tags at the connection port.
You can redefine the data ports to function as one of three types:
z Host Port
Use a host port definition for connecting Altitude APs with no OSPF routing function on this port.
z Third-Party AP Port
Use a third-party AP port definition for a port to which you will connect third-party APs. Only one
port can be configured for third-party APs.
Selecting this option prepares the port to support a third-party AP setup allowing the mapping of a
WM-AD to the physical port. The WM-AD settings permit the definition of policy, such as filters and
Captive Portal, which manage the traffic flow for wireless users connected to these APs.
The third-party APs must operate as layer-2 bridges. The third-party AP WM-AD is isolated from
the rest of the network. The Summit WM Controller assumes control over the layer-3 functions
including DHCP.
z Router Port
Use a router port definition for a port that you want to connect to a OSPF area to exchange routes to
other OSPF routers.
Altitude APs can be attached to a router port. The Summit WM Controller will create a virtual WM-
AD port and handle wireless device traffic in the same manner as a host port.
NOTE
Third-party access points must not be directly connected to a router or host port.
There is a fourth port type that is not configurable in the Summit WM GUI:
z WM Access Domain Services (WM-AD) interface
A WM-AD port is a virtual port created automatically on the Summit WM Controller 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 a WM-AD port and no routing is permitted on this
port.
