Chapter 43 Object Table 309 Configuration > Object > AP Profile > SSID > Security Profile > Add/Edit Security Profile LABEL DESCRIPTION Idle Timeout Authentication Type Key Length Enter the idle interval (in seconds) that a client can be idle before authentication is discontinued. Select a WEP authentication method. Choices are Open or Share key. Select the bit-length of the encryption key to be used in WEP connections. If you select WEP-64: • Enter 10 hexadecimal digits in the range of "A-F", "a-f" and "0-9" (for example, 0x11AA22BB33) for each Key used. or • Enter 5 ASCII characters (case sensitive) ranging from "a-z", "A-Z" and "0-9" (for example, MyKey) for each Key used. If you select WEP-128: • Enter 26 hexadecimal digits in the range of "A-F", "a-f" and "0-9" (for example, 0x00112233445566778899AABBCC) for each Key used. or • Enter 13 ASCII characters (case sensitive) ranging from "a-z", "A-Z" and "0-9" (for example, MyKey12345678) for each Key used. Key 1~4 Based on your Key Length selection, enter the appropriate length hexadecimal or ASCII key. The following fields are available if you set Security Mode to wpa, wpa2 or wpa2-mix. PSK Select this option to use a Pre-Shared Key with WPA encryption. Pre-Shared Key Enter a pre-shared key of between 8 and 63 case-sensitive ASCII characters (including spaces and symbols) or 64 hexadecimal characters. Cipher Type Select an encryption cipher type from the list. Idle Timeout Group Key Update Timer Pre-Authentication • auto - This automatically chooses the best available cipher based on the cipher in use by the wireless client that is attempting to make a connection. • tkip - This is the Temporal Key Integrity Protocol encryption method added later to the WEP encryption protocol to further secure. Not all wireless clients may support this. • aes - This is the Advanced Encryption Standard encryption method. It is a more recent development over TKIP and considerably more robust. Not all wireless clients may support this. Enter the idle interval (in seconds) that a client can be idle before authentication is discontinued. Enter the interval (in seconds) at which the AP updates the group WPA encryption key. This field is available only when you set Security Mode to wpa2 or wpa2-mix and enable 802.1x authentication. OK Cancel Enable or Disable pre-authentication to allow the AP to send authentication information to other APs on the network, allowing connected wireless clients to switch APs without having to re-authenticate their network connection.
