4 Configuring Access Point Security Table 11. Static WEP Field WEP Keys Authentication Description You can specify up to four WEP keys. In each text box, enter a string of characters for each key. If you selected "ASCII", enter any combination ASCII characters. If you selected "HEX", enter hexadecimal digits (any combination of 0-9 and a-f or A-F). Use the same number of characters for each key as specified in the "Characters Required" field. These are the RC4 WEP keys shared with the stations using the access point. Each client station must be configured to use one of these same WEP keys in the same slot as specified here on the AP. (See "Static WEP Rules" on page 48.) Characters Required: The number of characters you enter into the WEP Key fields is determined by the Key length and Key type you select. For example, if you use 128-bit ASCII keys, you must enter 26 characters in the WEP key. The number of characters required updates automatically based on how you set Key Length and Key Type. The authentication algorithm defines the method used to determine whether a client station is allowed to associate with an access point when static WEP is the security mode. Specify the authentication algorithm you want to use by choosing one of the following options: • Open System • Shared Key Note: You can also select both the Open System and Shared Key check boxes. Open System authentication allows any client station to associate with the access point whether that client station has the correct WEP key or not. This algorithm is also used in plain text, IEEE 802.1X, and WPA modes. When the authentication algorithm is set to "Open System," any client can associate with the access point. Note that just because a client station is allowed to associate does not ensure it can exchange traffic with an access point. A station must have the correct WEP key to be able to successfully access and decrypt data from an access point, and to transmit readable data to the access point. Shared Key authentication requires the client station to have the correct WEP key in order to associate with the access point. When the authentication algorithm is set to "Shared Key," a station with an incorrect WEP key will not be able to associate with the access point. Both Open System and Shared Key. When you select both authentication algorithms, client stations configured to use WEP in shared key mode must have a valid WEP key in order to associate with the access point. Also, client stations configured to use WEP as an open system (shared key mode not enabled) will be able to associate with the access point even if they do not have the correct WEP key. NOTE: After you configure the security settings, you must click Update to apply the changes and to save the settings.

Configuring Virtual Access Point Security

Configuring Access Point Security

NOTE:

After you configure the security settings, you must click

Update

to apply the

changes and to save the settings. Changing some access point settings might

WEP Keys

You can specify up to four WEP keys. In each text box, enter a string of

characters for each key.

If you selected “ASCII”, enter any combination ASCII characters. If you

selected “HEX”, enter hexadecimal digits (any combination of

0-9

and

a-f

A-F

Use the same number of characters for each key as specified in the

“Characters Required” field. These are the RC4 WEP keys shared with the

stations using the access point.

Each client station must be configured to use one of these same WEP keys in

the same slot as specified here on the AP. (See

“Static WEP Rules”

page 48.)

Characters Required:

The number of characters you enter into the WEP

Key fields is determined by the Key length and Key type you select. For

example, if you use 128-bit ASCII keys, you must enter 26 characters in the

WEP key. The number of characters required updates automatically based on

how you set Key Length and Key Type.

Authentication

The authentication algorithm defines the method used to determine whether a

client station is allowed to associate with an access point when static WEP is

the security mode.

Specify the authentication algorithm you want to use by choosing one of the

following options:

•

Open System

•

Shared Key

Note:

You can also select both the Open System and Shared Key check

boxes.

Open System

authentication allows any client station to associate with the

access point whether that client station has the correct WEP key or not. This

algorithm is also used in plain text, IEEE 802.1X, and WPA modes. When

the authentication algorithm is set to “Open System,” any client can associate

with the access point.

Note that just because a client station is allowed to

associate

does not ensure

it can exchange traffic with an access point. A station must have the correct

WEP key to be able to successfully access and decrypt data from an access

point, and to transmit readable data to the access point.

Shared Key

authentication requires the client station to have the correct

WEP key in order to associate with the access point. When the authentication

algorithm is set to “Shared Key,” a station with an incorrect WEP key will

not be able to associate with the access point.

Both

Open System and Shared Key

. When you select both authentication

algorithms, client stations configured to use WEP in shared key mode must

have a valid WEP key in order to associate with the access point. Also, client

stations configured to use WEP as an open system (shared key mode not

enabled) will be able to associate with the access point even if they do not

have the correct WEP key.
