This can come in handy in situations where users have an occasional need to access

the network. For example, contractors who do work for your company on an intermittent

but regular basis might need network access for 3 months at a time, then be off for 3

months, and back on for another assignment. You can enable and disable these user

accounts as needed, and control access as appropriate.

Enabling a User Account

To enable a user account, click the checkbox next to the user name and click

Enable

.

A user with an account that is

enabled

can log on to the wireless access points in your

network as a client.

Disabling a User Account

To disable a user account, click the checkbox next to the user name and click

Disable

.

A user with an account that is

disabled

cannot log on to the wireless access points in

your network as a client. However, the user remains in the database and can be enabled

later as needed.

Removing a User Account

To remove a user account, click the checkbox next to the user name and click

Remove

.

If you think you might want to add this user back in at a later date, you might consider

disabling

the user rather than removing the account altogether.

Session Monitoring

The D-Link DWL-2210AP provides real-time session monitoring information including

which clients are associated with a particular access point, data rates, transmit/receive

statistics, signal strength, and idle time.

The following Session Monitoring topics are covered here:

• Navigating to Session Monitoring

• Understanding Session Monitoring Information

• Viewing Session Information for Access Points

• Sorting Session Information

• Refreshing Session Information

Navigating to Session Monitoring

To view session monitoring information, click the

Cluster > Sessions

tab.

Description

Understanding Session Monitoring Information

The Sessions page shows information on client stations associated with access points

in the cluster. Each client is identified by user name and user

MAC

address, along with

the AP (location) to which it is currently connected.

To view a particular statistic for client sessions, select an item from the Display

drop-down list and click

Go

. You can view information on Idle Time, Data Rate, Signal,

Utilization, and so on; all of which are described in detail in the table below.

A “session” in this context is the period of time in which a user on a client device (station)

with a unique MAC address maintains a connection with the wireless network. The

session begins when the client logs on to the network, and the session ends when the

client either logs off intentionally or loses the connection for some other reason.

Details about the session information shown is described below.

A

session

is not the same as an

association

, which describes a client connection to a particular

access point. A client network connection can shift from one clustered AP to another within the

context of the same session. A client station can roam between APs and maintain the session.

For information about monitoring

associations

and

link integrity monitoring

, see “Associated

Wireless Clients” in this manual.

User Name

Indicates the client user name of IEEE 802.1x clients.

Note:

This field is relevant only for clients that are connected to

APs using IEEE 802.1x security mode

and

local authentication

server. (For more information about this mode, see “IEEE

802.1x” in “Configuring Security” .) For clients of APs using IEEE

802.1x with RADIUS server or other security modes, no

user name will be shown here.

AP Location

Indicates the location of the access point.

This is derived from the location description specified on the

Basic Settings tab.

User MAC Address

Indicates the MAC address of the user’s client device (station).

A

MAC

address is a hardware address that uniquely identifies

each node of a network.

Idle Time

Indicates the amount of time this station has remained inactive.

A station is considered to be “idle” when it is not receiving or

transmitting data.

Data Rate

The speed at which this access point is transferring data to the

specified client.

The data transmission rate is measured in

megabits per

second

(Mbps)

Session Monitoring

49

Signal

Indicates the strength of the radio frequency (RF) signal

the client receives from the access point.

The measure used for this is an

IEEE 802.1x

value

known as

Received Signal Strength Indication

(RSSI),

and will be a value between 0 and 100.

RSSI is determined by a an IEEE 802.1x mechanism

implemented on the network interface card (

NIC

) of the

client station.

Utilization

Utilization rate for this station.

For example, if the station is “active” (transmitting and

receiving data) 90% of the time and inactive 10% of the

time, its “utilization rate” is 90%.

Receive Total

Indicates number of total packets received by the client

during the current session.

Transmit Total

Indicates number of total packets transmitted to the

client during this session.

Error Rate

Indicates the percentage of time frames are dropped

during transmission on this access point.

Description

Viewing Session Information for Access Points

You can view session information for all access points on the network at the same time,

or set the display to show session information for a specified access point chosen from

the drop-down menu at the top of the screen.

To view information on all access points, select the

Show all access points

radio button

at the top of the page.

To view session information on a particular access point, select the

Show only this access

point

radio button and choose the access point name from the drop-down menu.

Sorting Session Information

To order (sort) the information shown in the tables by a particular indicator, click on the

column label by which you want to order things. For example, if you want to see the

table rows ordered by Utilization rate, click on the Utilization column label. The entries

will be sorted by Utilization rate.

Refreshing Session Information

You can force an update of the information displayed on the Session Monitoring page

by clicking the

Refresh

button.

This value should fall within the range of the advertised

rate set for the

IEEE 802.1x

mode in use on the access

point.

Setting the Ethernet (Wired) Interface

The following sections describe how to configure “Wired” address and related

settings on the D-Link DWL-2210AP:

• Navigating to Ethernet

• Setting the DNS Name

• Configuring an Internal LAN and a Guest Network

• Using VLANs for the Guest Network

• Configuring Internal Interface Ethernet Settings

• Configuring Guest Interface Ethernet Settings

• Updating Settings

The Ethernet Settings, including guest access, are not shared across the

cluster. These settings must be configured individually on the Administration

pages for each access point. To get to the Administration pages for an access

point that is a member of the current cluster, click on its IP Address link on

the Cluster > Access Points page of the current AP. For more information

about which settings are shared by the cluster and which are not, see

“Which Settings are Shared as Part of the Cluster Configuration and Which

Are Not?” in this manual.

Ethernet (Wired) Settings describe the configuration of your

Ethernet

local area network

(

LAN

).
