To define a WM-AD with no authentication:
1
From the main menu, click
WM-AD Configuration
. The
WM-AD Configuration
screen is
displayed.
2
In the left pane
WM Access Domains
list, click the WM-AD you want to configure with no
authentication. The
Topology
tab is displayed.
3
From the
Assignment by
drop-down list, select
SSID
.
4
Configure the topology for this WM-AD, then click
Save
. For more information, see
“Configuring
Topology for a WM-AD for Captive Portal” on page 99
. You must save your changes before moving
to the next tab.
5
Click the
Auth & Acct
tab.
6
Click
Configure Captive Portal Settings
. The
Captive Portal Configurations
screen is displayed.
7
Select
No Captive Portal Support
. You must save your changes before moving to the next tab.
8
Click the
Filtering
tab.
9
Define a default filter that will control specific network access for any wireless device users on this
WM-AD. For more information, see
“Configuring Filtering Rules for a WM-AD” on page 122
.
These rules should be very restrictive and the final rule should be a Deny All rule. The
non-authenticated filter for a WM-AD with no authentication will not have a Captive Portal page for
login.

Defining Priority Level and Service Class for WM-AD
Traffic
Voice over Internet Protocol (VoIP) using 802.11 wireless local area networks are enabling the integration
of internet telephony technology on wireless networks. Various issues including Quality-of-Service
(QoS), call control, network capacity, and network architecture are factors in VoIP over 802.11 WLANs.
Wireless voice data requires a constant transmission rate and must be delivered within a time limit. This
type of data is called isochronous data. This requirement for isochronous data is in contradiction to the
concepts in the 802.11 standard that allow for data packets to wait their turn, in order to avoid data
collisions. Regular traffic on a wireless network is an asynchronous process in which data streams are
broken up by random intervals.
To reconcile the needs of isochronous data, mechanisms are added to the network that give voice data
traffic or another traffic type priority over all other traffic, and allow for continuous transmission of
data.
In order to provide better network traffic flow, the Summit WM Controller, Access Points and Software
provides advanced Quality of Service (QoS) management. These management techniques include:
●
WMM (Wi-Fi Multimedia)
– Enabled globally on the Wireless AP, the standard provides
multimedia enhancements that improve the user experience for audio, video, and voice applications.
WMM is part of the 802.11e standard for QoS.
●
IP ToS (Type of Service) or DSCP (Diffserv Codepoint)
– The ToS/DSCP field in the IP header of a
frame is used to indicate the priority and Quality of Service for each frame. The IP TOS and/or
DSCP is maintained within CTP (CAPWAP Tunneling Protocol) by copying the user IP QoS
information to the CTP header—this is referred to as Adaptive QoS.
