HiPath Wireless Controller, Access Points and Convergence Software V7.11, User Guide 223
“Admin,” meaning this is the native topology of the HiPath Wireless
Controller management port
“Routed,” describing the L3 stub network segments
“Bridged at Controller,” which allows L2 forwarding between the wireless
clients and core network, or
“Bridged at AP,” which is implemented by local bridging done at the APs
themselves.
Exception Filters (available only if an L3 presence has been defined)
(As a matter of implementation, a topology that does not have a layer 3
presence (IP Address) assigned to it will have a “deny all” exception filter
attached to it. This filter will not be configurable or even visible to the
administrator.)
Certificates (only allowed if an L3 presence has been defined)
Multicast filters
The main Topologies GUI includes a field for configuring the internal VLAN. This
field's default value is 1 as in previous releases. This value can also be changed
to match the existing network configuration.
5.1.2 Policy
In general, a Policy Profile is defined as a collection of attributes and rules to be
applied to the traffic of ports and stations. The Enterasys Policy Manager's policy
profile permits the definition of default VLAN and Class of Service assignments
that can be used when other more specific policy assignment mechanisms (that
is, policy rule matches) do not apply.
On HiPath platforms, the Policy defines the binding of Default Topology, Default
Rate Profiles, and Default filter rules.
In general, the Class of Service refers to a set of attributes that define the
importance of a frame, while forwarded through the network ,relative to other
packets, and to the maximum throughput per time unit that a station or port
assigned to the policy is permitted. The Class of Service defines actions to be
taken when rate limits are exceeded.
On the HiPath Wireless Controller, the configuration of the CoS is part of WLAN
Service while the Rate Control and Filtering are part of Policy definition. The
actions allowed by the HiPath implementation are: allow or drop.
Policies don't need to be fully specified; Unspecified attributes are retained by the
user or inherited from Global Policy definitions
