Security Profile Table - Update
(requires Level 10 permission)
Use the Security Profile Table - Update page to change the configuration of a security profile.
The options available on this page are determined by the L2 security
selection in step 1; options are available only if they can be configured for
the chosen L2 security selection. To modify Security Profile parameters:
- In the L2 Modes Allowed area, select one of the following Layer 2
security modes:
- Clear: The WLAN does not require authentication
or encryption, and the WLAN does not secure client traffic. This is the default
setting.
- 802.1X: Can provide 802.1X authentication and WEP64 or WEP128 encryption.
- Static WEP keys: Requires that stations use a WEP key (see step 6).
- WPA: Requires 802.1X Radius server authentication with one of the EAP
types; see step 4 to select a pre-configured
Radius server profile.
- WPA PSK: Uses the TKIP encryption protocol and requires a shared key (see step
11 to enter the shared Key).
- WPA2: Requires 802.1x Radius server authentication with one of the EAP
types (see
step 4 to select a pre-configured
Radius server profile).
- WPA2 PSK: Uses the CCMP-AES encryption protocol and requires a pre-shared key
(see step 12 to enter the pre-shared key).
- MIXED: Allows both WPA and WPA2
clients using a single security profile.
- MIXED PSK: Allows pre-shared
key clients to use a single security profile.
- In the Data Encrypt area, select one of the following (available choices are
determined by the L2 Mode selected):
- WEP64: A 64-bit WEP key is used to encrypt packets.
- WEP128: A 128-bit WEP key is used to encrypt packets.
- TKIP: Encryption algorithm used with WPA; uses a 128-bit key and
64-bit Initialization Vector (IV).
- CCMP-AES: A 128-bit block key is used to encrypt packets with WPA2.
- CCMP/TKIP Use the Counter Mode with Cipher Block Chaining (CCMP)
encryption protocol that replaces TKIP, the mandatory protocol in WPA, and WEP.
If you select WEP64 or WEP128, you need to specify a WEP key, as
described in step 6. If you specify TKIP for WPA-PSK or
CCMP-AES for WPA2-PSK, a
pre-shared key must be set, as described in step 12.
- From the Primary Radius Profile Name list, select one of the configured
Radius Server Profiles for use as the primary server or select the No
Radius option. If no Radius Server Profiles have been configured, the
selectable list
is unavailable and the text "No Data for Primary Radius Profile
Name" displays. To configure a Radius Server Profile, click the Radius link under the Security heading on the Navigation Pane.
- From the
Secondary Radius Profile Name list, select one of the configured Radius Server
Profiles for use as the secondary server or select the No Radius
option. If no Radius Server Profiles have been configured, the selectable list is
unavailable and the text "No Data for Primary Radius Profile Name"
displays. To configure a Radius server profile, click the Radius link
under the Security heading on the Navigation Pane.
- In the WEP Key box, specify a WEP key. If you selected Static
WEP Keys in step 2, you need to specify a WEP key in hexadecimal or text string format.
- A WEP64 key must be 5 octets long, which you can specify as 10 hexadecimal digits
(the hexadecimal string must be preceded with 0x) or 5 printable alphanumeric
characters (the ! character cannot be used).
For example, 0x619B947A3D is a valid hexadecimal value, and wpass is a valid alphanumeric string.
- A WEP128 key must be 13 octets long, which you can specify as 26 hexadecimal digits
(the hexadecimal string must be preceded with 0x) or 13 printable alphanumeric
characters (the ! character cannot be used).
For example, 0xB58CE2C2C75D73B298A36CDA6A is a valid hexadecimal value, and mypass8Word71 is a valid
alphanumeric string.
- In the Static WEP Key Index box, type the index number to be used with
the WEP key for encryption and decryption. A station can have up to four
static WEP keys configured. The static WEP key index must be an integer
between 1 through 4 (although internal mapping is performed to handle wireless
clients that use 0 through 3 assignments).
- In the Re-Key Period box, type the duration that the key is valid. Specify a value from 0 to 65,535 seconds. The default re-key value is zero (0). Specifying 0
indicates that re-keying is disabled, which means that the key is valid for the entire session, regardless of the
duration.
- In the Captive Portal list, select one of the following:
- Disabled: Disables Captive Portal.
- WebAuth: Enables a WebAuth Captive Portal. This
feature can be set for all L2 Mode selections.
- If you want to use a third-party Captive Portal solution from a company such
as Bradford, Avenda, or CloudPath change the value for Captive Portal
Authentication Method to external.
- If 802.1X is to be used, in the 802.1X Network Initiation list, select one of the following:
- On: The controller initiates 802.1X authentication by sending an EAP-REQUEST
packet to the client. By
default, this feature is enabled.
- Off: The client sends an EAP-START packet to the controller to
initiate 802.1X authentication. If
you select this option, the controller cannot initiate 802.1X authentication.
- If the Static WEP Key mode to be used, in the Shared Key Authentication list, select one of the following:
- On: Allows 802.1X shared key authentication.
- Off: Uses Open authentication. By
default, this feature is off.
- In the Pre-shared Key text box, enter the key
that is to be used if the WPA-PSK or WPA2-PSK option was selected in step 2
above. The key can be from 8 to 63 ASCII characters or 64 hex characters (hex
keys must use the prefix "0x" or the key will not work).
- In the Group Keying Interval text box, enter the time in seconds for the
interval before a new group key is distributed.
- In the Key Rotation drop-down list, select whether to enable or disable this
feature.
- For Reauthentication, select one of the following:
- On: Causes the controller to honor and enforce the
"Session-timeout" Radius attribute that may be present in a Radius Access-Accept packet. A customer would use this option if the Session-timeout
attribute is used to require stations to reauthenticate to the network
(802.1X) at a specified period. If "Session-timeout" is not used,
there is no reason to enable reauthentication.
- Off: Disables reauthentication for this security profile.
- In the MAC Filtering list, select one of the following:
- On: Enables MAC Filtering for this security profile.
- Off: Disables MAC Filtering for this security profile.
- In the Firewall Capability drop-down list, select one of the following:
- Configured: The controller defines the policy through configuration
of the Firewall filter-id.
- Radius-configured: The Radius server provides the policy after
successful 802.1X authentication of the user. This option requires the Radius server have the filter-id configured. If this is not configured, the
firewall capability is not guaranteed.
- None: Disables the Firewall Capability for this security profile.
- In the Firewall Filter ID text box, enter the firewall filter-id that
is used for this security profile. The filter-id is an alphanumeric
value that defines the firewall policy to be used on the controller, when the
firewall capability is set to configured. For example, 1.
- In the Security Logging drop-down list, select one of the following:
- On: Enables logging of security-related messages for this security profile.
- Off: Disables logging of security-related messages for this security
profile
- In the Passthrough Firewall Filter ID text box, enter a firewall filter ID
that was created using Configuration > Qos > System Settings > QoS
and Firewall Rules > Add. The filter ID is an alphanumeric value that
defines the firewall policy to be used on the controller for a Captive
Portal-enabled client that has no authentication.
- Click OK.
