2. Default authorized policy — This is a mandatory policy that applies to the traffic of
authenticated stations for which no other policy was explicitly specified. It can be the same as
the default non-authorized policy.
3. Third party AP policy — This policy applies to the list of MAC addresses corresponding to the
wired interfaces of third party APs specifically defined by the administrator to be providing
the RF access as an AP WLAN Service. This policy is only relevant when applied to third
party AP WLAN Services.
Classes of Service
In general, Class of Service (CoS) refers to a set of attributes that define the importance of a frame
while it is forwarded through the network relative to other packets, and to the maximum
throughput per time unit that a station or port assigned to a specific policy is permitted. The CoS
defines actions to be taken when rate limits are exceeded.
All incoming packets may follow these steps to determine a CoS:
• Classification - identifies the first matching rule that defines a CoS.
• Marking - modifies the L2 802.1p and/or L3 ToS based on CoS definition.
• Rate limiting (drop) is set.
The system limit for the number of CoS profiles on a controller is identical to the number of
policies. For example, the maximum number of CoS profiles on a WLC711 is 64.
WLAN Services
A WLAN Service represents all the RF, authentication and QoS attributes of a wireless access
service offered by the SCALANCE IWLAN Controller and its APs. A WLAN Service can be one of
the following types:
• Standard — A conventional service. Only APs running SCALANCE IWLAN software can be
part of this WLAN Service. This type of service can be used as a Bridged at Controller,
Bridged at AP, or Routed Topology. This type of service provides access for mobile stations.
Policies can be associated with this type of WLAN service to create a VNS.
• Third Party AP — A Wireless Service offered by third party APs. This type of service provides
access for mobile stations. Policies can be assigned to this type of WLAN service to create a
VNS.
• Dynamic Mesh and WDS (Static Mesh)— This is to configure a group of APs organized into a
hierarchy for purposes of providing a Wireless Distribution Service. This type of service is in
essence a wireless trunking service rather than a service that provides access for stations. As
such, this service cannot have policies attached to it.
• Remote — A service that resides on the edge (foreign) SCALANCE IWLAN Controller.
Pairing a remote service with a remoteable service on the designated home SCALANCE
IWLAN Controller allows you to provision centralized WLAN Services in the mobility
domain. This is known as centralized mobility.
