6 Refer to the IP Filtering field to optionally enable the IP filtering feature, and (if enabled) apply
existing IP filters (and their rules and permissions) to the WLAN.
NOTE
For an overview of IP Filtering and how to create a filter, see “Configuring IP Filtering” on page 188 . For
information on applying an existing filter to the IP packet flow of a WLAN, see “Applying a Filter to LAN1, LAN2
or a WLAN (1-16)” on page 191 .
7 Click Apply to save any changes to the WLAN screen. Navigating away from the screen without
clicking Apply results in all changes to the screens being lost.
8 Click Cancel to securely exit the New WLAN or Edit WLAN screen and return to the Wireless
Configuration screen.
Configuring WLAN Security Policies
As WLANs are being defined for an access point, a security policy can be created or an existing policy
edited (using the
Create or Edit buttons within the Security Configuration screen) to best serve the
security requirements of the WLAN. Once new policies are defined, they are available within the New
WLAN or Edit WLAN screens and can be mapped to any WLAN. A single security policy can be used
by more than one WLAN if its logical to do so. For example, there may be two or more WLANs within
close proximity of each other requiring the same data protection scheme.
To create a new security policy or modify an existing policy:
1 Select Network Configuration > Wireless > Security from the access point menu tree.
The Security Configuration screen appears with existing policies and their attributes displayed.
Enable Rate
Limiting Select this checkbox to set MU rate limiting values for this
WLAN in both the upstream and downstream direction.
Once selected, two fields display enabling you to set MU
radio bandwidth for each associated MU in both the wired-
to-wireless and wireless-to-wired directions. Set an
allocation between 100 and 300,000 kbps. The default
value is 1000 kbps. For more information, see
“Configuring
MU Rate Limiting” on page 184 .
Quality of Service
Policy If QoS policies are undefined (none), select the Create
button to launch the New QoS Policy screen. Use this
screen to create a QoS policy, wherein data traffic for the
new or revised WLAN can be prioritized to best suit the
MU transmissions within that WLAN. For more information,
see
“Setting the WLAN Quality of Service (QoS) Policy” on
page 156 .
Enable IP Filtering Selecting this checkbox allows the WLAN to employ filter
policies and rules to determine which IP packets are
processed normally over the WLAN and which are
discarded. If discarded, a packet is deleted and ignored
(as if never received).
IP Filtering Select the IP Filtering button to display a screen where
existing IP filter policies can be applied to the WLAN to
allow or deny IP packets in either an incoming or outgoing
direction based on the rules defined for the policy.
