• Topology now allow for VLANs without L3 presence
Note: The concepts introduced in V7.0 facilitate the integration between HiPath.
WLAN and the Enterasys Policy Manager. However, discussion about their
integration, the communication between the two, provisioning model, and so on
are not part of this document.
The configurable high-level distinct umbrella elements of a VNS are:
• Topology
• Policy
• WLAN Services
It is important to note, however, that Topologies are associated with Policies,
which makes configuration of a VNS association between a WLAN Service and
a Policy (that inturn defines a Policy).
5.1.1 Topology
A Topology is represented by the configurable networking parameters and
options which define the HiPath Wireless Controller and APs’ interactions with the
other networking elements. The main attributes of a topology are:
• Name
• Mode, which can be one of the following:
– Routed
– Bridge Traffic Locally at AP
– Bridge Traffic Locally at HWC
• VLAN ID
• Tagged or untagged
• Port attachments to the network for the HiPath Wireless Controller only. This
is not required for Routed or Bridge Traffic Locally at AP topologies, but it is
required for Bridge Traffic Local at HWC.
• Interface (L3) definition, i.e., the IP address assigned to the HiPath Wireless
Controller’s interface attached to the network described by a given topology
(optional)
• Topologu type, which is the intuitive description of traffic forwarding
mechanisms. The options are:
– “Physical,” describing an Ethernet port
