Settings

VLAN Name

A unique name for a VLAN configured on the access point. This setting is configured by the user and is for information only. The VLAN name is not used by the switch or access point as a parameter for determining the destination of data.

VLAN Enable

Enables or disables the VLAN.

Default Priority

Use the drop-down menu to select the Class of Service (CoS) for each VLAN.

Default Policy Group

Use the drop-down menu to apply a policy group (set of Layer 2, 3, and 4 filters) for each VLAN. Each filter within a policy group can be configured to allow or deny a certain type of traffic.

Enhanced MIC Verification for WEP

This setting enables Message Integrity Check (MIC), a security feature that protects your WEP keys by preventing attacks on encrypted packets called bit-flip attacks. During a bit-flip attack, an intruder intercepts an encrypted message, alters it slightly, and retransmits it, and the receive accepts the retransmitted message as legitimate. The MIC, implemented on both the access point and all associated client devices, adds a few bytes to each packet to make the packets tamperproof. Select MMH from the drop-down menu to enable MIC or select None.

Temporal Key Integrity Protocol

TKIP, also known as WEP key hashing, is an additional WEP security feature that defends against an attack on WEP in which the intruder uses an encrypted segment called the initialization vector (IV) in encrypted packets to calculate the WEP key. Use the drop-down menu to choose either None or Cisco.

WEP Key Rotation Interval

This option enables broadcast key rotation by setting a key rotation interval. With broadcast, or multicast, WEP key rotation enabled, the access point provides a dynamic broadcast WEP key and changes it at the interval you select. To enable key rotation, enter the rotation interval in seconds. Enter a 0 to turn key rotation off.

Alert?

Determine if you want to print the packet data to the console log for troubleshooting.

Encryption Key

For 40-bit encryption, enter 10 hexadecimal digits; for 128-bit encryption, enter 26 hexadecimal digits. Hexadecimal digits include the numbers 0 through 9 and the letters A through F. The WEP key you use to transmit data must be set up exactly the same on your access point and any wireless devices with which it associates. For example, if you set WEP Key 3 on your wireless LAN adapter to 0987654321 and select it as the transmit key, you must also set WEP Key 3 on the access point to exactly the same value.

Key Size

Use the drop-down menu to select 40-bit or 128-bit encryption for each key. The not set option clears the key. You can disable WEP altogether by selecting not set for each key.
