Using MAC Filtering
Field Description
Filter
To set the MAC Address
Filter
, click one of the following radio buttons:
• Allow only stations in the list
• Allow any station unless in list
Stations List
To add a MAC Address to Stations List, enter its 48-bit MAC address into
the lower text boxes, then click
Add
.
The MAC Address is added to the Stations List.
To remove a MAC Address from the Stations List, select its 48-bit MAC
address, then click
Remove
.
The stations in the list will either be allowed or prevented from accessing
the AP based on how you set the Filter.
Updating Settings
To apply your changes, click
Update
.
Field
Description
This page allows you to control access to D-Link DWL-2210AP based on
Media
Access Control
(MAC) addresses. Based on how you set the filter, you can
allow
only
client stations with a listed MAC address or
prevent
access to the stations listed.
For the Guest interface,
MAC
Filtering settings apply to both
BSS
es.
On a two-radio AP, MAC Filtering settings apply to both radios.

The D-Link DWL-2210AP allows you to balance the distribution of wireless client
connections across multiple access points. Using load balancing, you can prevent
scenarios where a single access point in your network shows performance degradation
because it is handling a disproportionate share of the wireless traffic.
The following sections describe how to configure Load Balancing on your wireless
network:
Understanding Load Balancing
Like most configuration settings on the D-Link DWL-2210AP, load balancing settings
are shared among clustered access points.
Identifying the Imbalance: Overworked or Under-utilized Access Points
A typical scenario is that a comparison of Session Monitoring data for multiple
access points allows you to identify an access point that is consistently handling a
disproportionately large percentage of wireless traffic. This can happen when location
placement or other factors causes one access point to transmit the strongest signal
to a majority of clients on a network. By default, that access point will receive most of
client requests while the other access points stay idle much of the time.
Imbalances in distribution of wireless traffic across access points will be evident in
Session Monitoring statistics, which will show higher “Utilization” rates on overworked
APs and conversely, higher “Idle” times on under-utilized APs. An AP that is handling
more than its fair share of traffic might also show slower data rates or lower transmit/
receive rates due to the overload.
In some cases you might want to set limits for only one access point that is
consistently overutilized. You can apply unique settings to a particular access
point if it is operating in standalone mode. (See “Understanding Clustering” and
“Navigating to Access Points Management” in this manual.)

Specifying Limits for Utilization and Client Associations
You can correct for imbalances in network AP utilization by enabling load balancing
and setting limits on utilization rates and number of client associations allowed per
access point.
Load Balancing and QoS
Load balancing also plays a part in contributing to
Quality of Service
(QoS) for
Voice
Over IP
(VoIP) and other such time-sensitive applications competing for bandwidth
and timely access to the air waves on a wireless network. For more information about
configuring your network for QoS, see “Configuring Queues for Quality of Service
(QoS)” in this manual.
Navigating to Load Balancing Settings
On the Administration UI, navigate to the
Advanced > Load Balancing
tab, and update the
fields as described in the next section.

Load Balancing
To enable load balancing on this access point,
click
Enable
. To disable load balancing on this
access point, click
Disable
.
Utilization for No New Associations
Utilization rate limits relate to wireless
bandwidth utilization.
Provide a bandwidth utilization rate percentage
limit for this access point to indicate when to
stop accepting new client associations.
When the utilization rate for this access point
exceeds the specified limit, no new client
associations will be allowed on this access
point.
If you specify 0 in this field, all new
associations
will be allowed regardless of the utilization rate.
Configuring Load Balancing
To view the current Utilization Rates for access points, click Cluster > Sessions on the
Administration Web pages. (See “Session Monitoring” in this manual.)
Even when clients are disassociated from an AP, the network will still provide continuous
service to client stations if another access point is within range so that clients can
reconnect to the network. Clients should automatically retry the AP they were originally
connected to and other APs on the subnet. Clients who are disassociated from one AP
should experience a seamless transition to another AP on the same subnet.
Load Balancing settings apply to the AP load as a whole. When Guest access is enabled,
the settings apply to both Internal and Guest networks together.
On a two-radio access point, Load Balancing settings apply to both radios but the load
of each radio is calculated independently and includes both the Internal and Guest
network (when Guest access is enabled).
Field
Description
To configure load balancing,
enable
“Load Balancing” and set limits and behavior to
be triggered by a specified utilization rate of the access point.
