MSM7xx Controllers Configuration Guide v6.4.0

7 Working with VSCs
Key concepts
A VSC (virtual service community) is a collection of configuration settings that define key operating
characteristics of the controller and controlled APs. In most cases, a VSC is used to define the
characteristics of a wireless network and to control how wireless user traffic is distributed onto the
wired network.
Multiple VSCs can be active at the same time, allowing for great flexibility in the configuration of
services. Up to 64 VSC profiles can be configured, provided proper licensing is used.
In the following scenario, four VSCs are used to support different types of wireless users. Each VSC
is configured with a different wireless network name (SSID), and the quality of service (QoS) feature
is used to classify user traffic priority.
VSC #2
SSID=Phone
QoS=Very High Priority
VSC #1
SSID=Guest
QoS=Low priority
VSC #3
SSID=Employee
QoS=Normal priority
VSC #4
SSID=Video
QoS=High priority
Backbone Network

#1 #2 #1 #2

Binding VSCs to APs
VSCs are defined on the controller, creating a global pool of services. From this pool, specific
VSCs are then bound to one or more groups (and the APs in the groups), to provide a homogeneous
wireless offering. See “Binding VSCs to groups” (page 163).
NOTE: The MSM760, MSM765 zl, and MSM775 zl controllers support up to 64 VSCs. The
MSM720 supports 16 VSCs by default, and 64 VSCs when the Premium Mobility License is
installed. Controlled APs support a maximum of 16 VSCs.
Viewing and editing VSC profiles
The VSC profiles list shows all VSCs that are currently defined on the controller. To open the list,
select VSCs in the Network Tree.
