For TTLS/PEAP, Inner Algorithm (MSCHAPv2, EAP-MS-CHAPv2), Outer ID, and Password.
1 Introduction WPA/RSN WPA/RSN This section covers the following topics: Introduction to WPA/RSN • Introduction to WPA/RSN on page 1-6. • EAP Algorithms on page 1-7. • Certificate Files on page 1-7. • Key Hierarchy and Configuration on page 1-7. • Protocol Conformance Testing on page 1-8. Individual virtual stations can be configured with WPA or RSN authentication. A vSTA can be configured to use either PSK or full 802.1X/EAP authentication. RSN does the strong security of IEEE 802.11i.
Introduction WPA/RSN 802.1X EAPOL-Key packets are used by WPA and RSN to negotiate and derive pairwise keys used to protect unicast traffic. Group key handshake is used to deliver the group key to each virtual station for protecting multicast and broadcast class 3 data frames. • Data Privacy (Encryption) – TKIP or AES-CCM (that is, CCMP) is used to replace WEP with more sophisticated cryptographic and security techniques.
1 Introduction Files The 4-way handshake (obtain/install PTK) is processed as follows: • EAPOL-Key Message exchange (four messages) • Verify that a live peer holds the PMK. • Verify that the PMK is current. • Obtain a fresh PTK from the PMK. • Install the Pairwise encryption and integrity keys into IEEE 802.11. • Confirm the installation of the keys. The Group Key Handshake (obtain/install Group Transient Key) is processed using an EAPOL-Key Message exchange (two messages).
Introduction Files Table 1-2. Directory Directories and Files Maintained in the Flash File System (Continued) Files Description • keyfile: The keyfile is a reserved file that contains the IxWLAN authorization code. It is a hidden file and is shown only in the directory list in the CLI administrative mode. Do not delete this file or try to access or modify it. The system needs it. /Cache Encapsulated certificate file passwords When a certificate file is imported into IxWLAN, a password is needed.

The Command Line Interface (CLI) Virtual Station Setup and Control Commands Example: [wport1]IxWLAN -> assoc vsta 1 [wport1]IxWLAN -> OK [wport1]IxWLAN -> vSTA ID:1 NOTIFY Operation ASSOC succeeded - TUE JUL 15 03:08:38 2003 [wport1]IxWLAN -> When a virtual station is configured for WPA-PSK authentication, this command shows additional AKMP information.
5 The Command Line Interface (CLI) Virtual Station Setup and Control Commands The following command starts the authentication sequence for all virtual stations in a specified group.
The Command Line Interface (CLI) Virtual Station Setup and Control Commands addresses defined by the WLAN Base MAC Address and WLAN MAC Mask configured for the specified wport (see set wlanmac on page 5-85 and set wlanmask on page 5-85). ip : Specifies the base/starting value to be used for virtual station IP addresses. This parameter is needed for the first autoconf command and should not be specified for subsequent commands. Default: Last IP address + 1.
5 The Command Line Interface (CLI) Virtual Station Setup and Control Commands [mode internal | external]: If mode is internal, virtual station(s) generate data using Ping (ICMP Echo Request) packets. Each virtual station runs a ping transmitter process. The packets contain virtual station IP and MAC source address. If internal is specified, the target parameter must also be specified. If mode is external, data for virtual station(s) is generated by an external host connected to the same LAN as IxWLAN.
The Command Line Interface (CLI) Virtual Station Setup and Control Commands 802.3 MAC address. If layer is 3, frames are captured based on the source IP address. The default value is 3. [fragmentthreshold ]: can be a value in the 256…2346 range and defines the fragmentation threshold for the virtual station(s) configured by this command. The fragmentation threshold limits the number of bytes in any 802.11 frame transmitted by the vSTA. If is set to 2346 (that is, the maximum 802.
5 The Command Line Interface (CLI) Virtual Station Setup and Control Commands [outeridentity ]: If eapalgorithm is peap or ttls, this parameter assigns a separate user ID for use in Phase 1 authentication. It can be up to 64 characters in the range A…Z, a…z, 0…9, or other legal characters: period (.), dash (-), at-sign (@). [password ]: If eapalgorithm is peap or ttls, this parameter assigns a user password for use in Phase 2 authentication.
