vSTA->New Group->Security
This section of the New Group dialog defines whether the virtual station uses
security, the type of authentication to be used for authenticating with the System
Under Test, and the associated cipher to use.
Encryption : Select On or Off from the drop-down list box to enable/disable
encryption.
Authentication : Select an authentication type: Open System, Shared Key, RSN,
RSN-PSK, WPA, or WPA-PSK. If you select RSN or WPA , define user creden-
tial parameters in the EAP tab. If you select RSN-PSK or WPA-PSK , define a
pre-shared key or passphrase in the PSK tab.
Cipher : For Open System or Shared Key Authentication, WEP is the only valid
selection. For RSN, RSN-PSK, WPA, and WPA-PSK Authentication, select
TKIP or AES-CCM (that is, CCMP cipher mode).
Fast Radius: The default value of this attribute is Disabled . When a vSTA is
configured for fast RADIUS reconnection and the vSTA has cached the TLS ses-
sion information, it tries fast resumption in subsequent 802.1X authentication
exchanges by using the session_id and master_key from that cached TLS session.
PMKSA Cache : Enables the use of the cached PMKSA information when
(re)associating. The default value is Enabled . Each entry in the PMKSA cache
contains the BSSID of the corresponding AP, a PMKID, and the Pairwise Master
Key (PMK). A PMKSA can be obtained by 802.1X authentication or by pre-
authentication.
vSTA->New Group->Security WEP Tab
For Open System or Shared Key Authentication and WEP Cipher mode, this sec-
tion of the New Group dialog allows you to define up to four shared keys, as
shown in
Figure 4-41 on page 4-33.
