Configuring

WEP 64/128/

152 Security

Note

If you configure WEP 64/128/152 security for a radio, you cannot

also enable 802.1x authentication for that radio. 802.1x security

uses rotating WEP keys that are automatically generated.

In your 802.11b or 802.11a network, you can configure static WEP keys to

provide security between the access points and the wireless end

devices. To use static WEP keys, your radios must support WEP

encryption. All access points and wireless end devices on a particular

network must use the same WEP encryption type and the same WEP

transmit key. You should periodically change this WEP transmit key to

prevent an unauthorized person with a sniffing tool from monitoring

your network and discovering the WEP key.

Since, static WEP keys can be difficult to update, the AT-WA7500 access

point and other Allied Telesyn products let you enter up to four WEP

keys, and then pick a WEP transmit key (1-4). It is easier to rotate the WEP

transmit key than to individually change all the WEP keys.

 WEP 64 has four 40-bit encryption keys and one 24-bit

initialization vector (IV) key. Enter five ASCII characters or five hex

pairs for the WEP keys.

 WEP 128 provides a higher degree of encryption protection. It has

four 104-bit encryption keys and one 24-bit IV key. Enter 13 ASCII

characters or hex pairs.

 WEP 152 provides the highest degree of encryption protection. It

has four 128-bit encryption keys and one 24-bit IV key. Enter 16

ASCII characters or hex pairs.
