HP ProCurve 520wl Wireless Access Point - Manual (Page 79)

Advanced Configuration
Authentication Mode Setting Authentication Method Employed Encryption Method Employed
None None None or manually configured Static WEP
settings (from Configure > Security >
Encryption screen)
802.1x 802.1x Dynamic WEP Keying
Mixed 802.1x or None (depends on a client's
configuration) Dynamic WEP Keying or Static WEP (depends
on client's configuration)
WPA 802.1x Dynamic TKIP Keying
WPA-PSK Manually configured Pre-shared Key Dynamic TKIP Keying
NOTE
Before enabling the 802.1x, Mixed, or WPA mode, the 802.1x server should be configured. Set the encryption
key in Mixed mode after the authentication is set to Mixed mode.
Enable WEP Encryption
Follow these steps to set up WEP encryption on an AP:
1. Click Configure > Security > Authentication.
2. Set Authentication Mode to None (if necessary).
3. Click the Encryption tab.
4. Place a check mark in the box labeled Enable Encryption (WEP).
5. Enter one to four Encryption Keys in the fields provided. Keep in mind the following:
• If entering more than one Key, use the same number of characters for each Key. All Keys need to be the same
Key Size (64, 128, or 152-bit).
• You can enter the Encryption Keys in either hexadecimal or ASCII format.
• You need to configure your wireless clients to use the same Keys in order for the clients and the AP to
communicate.
6. Select the Key that the AP will use to encryption outgoing data from the Encrypt Data Transmissions Using
drop-down menu. By default, this parameter is set to Key 1.
7. Click OK.
Enable 802.1x Security
Follow these steps to enable 802.1x only:
1. Click Configure > Security > Authentication.
2. Set Authentication Mode to 802.1x.
3. Select an Encryption Key Length.
• An 802.11b AP supports 64-bit and 128-bit encryption.
• An 802.11a or 802.11b/g AP supports 64-bit and 128-bit encryption.
4. Enter a Re-keying Interval.
• The Re-keying Interval determines how often a client’s encryption key is changed and can be set to any value
between 60 - 65535 seconds. Rekeying frustrates hacking attempts without taxing system resources. Setting
a fairly frequent rekey value (900 seconds=15 minutes) effectively protects against intrusion without disrupting
network activities.
5. Click OK to save the changes.
6. If you have not already done so, configure the RADIUS authentication settings (see
RADIUS Authentication with
802.1x for details).
7. Reboot the Access Point.
