VSC on controller
For more information on controller configuration, see the MSM7xx Controllers Management
and Configuration Guide .
Ingress
 SSID (LAN port): SSID is retrieved using the location-ware function client runs on AP.
 VLAN (LAN or Internet port): Traffic with a VLAN ID is handled by the VSC with a
matching VLAN definition.
 Untagged (LAN port): Untagged traffic on the LAN port may originate from wired
users, or APs operating in autonomous mode (HP or third-party).
Features
 Authentication: The controller supports 802.1X, MAC, or HTML authentication. To
validate user login credentials the controller can use the local user accounts or make use
of a third-party authentication server (Active Directory or RADIUS).
 Access control features: The controller provides a number of features that can be
applied to user sessions. Features can be enabled globally or on a per-account basis.
Egress
The controller enables user traffic to be forwarded to different output interfaces, which
include the routing table, VLAN ID, or IP GRE tunnel.
Quality of service (QoS)
The quality of service (QoS) feature provides a number of different mechanisms to prioritize
wireless traffic sent to wireless client stations. This is useful when the AP handles wireless
traffic from multiple devices (or multiple applications on a single device), that have different
data flow requirements.
QoS can be enabled on a VSC (see Quality of service on page 4-12 ) or on a local mesh link
(see Quality of service on page 7-6 ).
The QoS feature defines four traffic queues based on the Wi-Fi Multimedia (WMM) access
categories. In order of priority, these queues are:
