Enable 802.1x Security
Follow these steps to enable 802.1x on an SSID/VLAN pair:
1. Set Security Mode to 802.1x.
2. 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.
3. 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.
Enable Mixed Mode (802.1x and WEP Encryption)
Follow these steps to use both 802.1x and WEP Encryption
simultaneously (clients that do not support 802.1x use WEP Encryption
for security purposes) on an SSID/VLAN pair:
1. Set Security Mode to Mixed.
