Parameters

server-only-authentication|use-sha256-akm]
wpa-wpa2Modifies TKIP-CCMP (WPA/WPA2) related parameters
exclude-wpa2-tkipExcludes the Wi-Fi Protected Access II (WPA2) version of TKIP. It supports the WPA version of TKIP only. This option is disabled by default.
opp-pmk-cachingUses opportunistic key caching (same Pairwise Master Key (PMK) across APs for fast roaming with EAP.802.1x. This option is enabled by default.
pmk-cachingUses cached pair-wise master keys (fast roaming with eap/802.1x). This option is enabled by default.
preauthenticationUses pre-authentication mode (WPA2 fast roaming)
use-sha256-akmUses sha256 authentication key management suite
wpa-wpa2 handshake [attempts <1-5>|init-wait <5-1000000>|priority [high|normal]|
timeout <10-5000> {10-5000}]
wpa-wpa2Modifies TKIP-CCMP (WPA/WPA2) related parameters
handshakeConfigures WPA/WPA2 handshake parameters
attempts <1-5>Configures the total number of times a message is transmitted towards a non-responsive client
  • <1-5> – Specify a value from 1 - 5. The default is 2.
init-wait <5-1000000>Configures a minimum wait-time period, in microseconds, before the first handshake message is transmitted from the AP. This option is disabled by default.
  • <5-1000000> – Specify a value from 5 - 1000000 microseconds.
priority [high|normal]Configures the relative priority of handshake messages compared to other data traffic
  • high – Treats handshake messages as high priority packets on a radio. This is the default setting.
  • normal – Treats handshake messages as normal priority packets on a radio
timeout <10-5000> <10-5000>Configures the timeout period, in milliseconds, for a handshake message to retire. Once this period is exceeded, the handshake message is retired.
  • <10-5000> – Specify a value from 10 - 5000 millisceonds. The default is 500 milliseconds.
  • <10-5000> – Optional. Configures a different timeout between the second and third attempts'
wpa-wpa2 key-rotation [broadcast|unicast] <30-86400>
wpa-wpa2Modifies TKIP-CCMP (WPA/WPA2) related parameters
key-rotationConfigures parameters related to periodic rotation of encryption keys. The periodic key rotation parameters are broadcast, multicast, and unicast traffic.
broadcast <30-86400>Configures the periodic rotation of keys used for broadcast and multicast traffic. This parameter specifies the interval, in seconds, at which keys are rotated. This option is disabled by default.
  • <30-86400> – Specify a value from 30 - 86400 seconds.
unicast <30-86400>Configures a periodic interval for the rotation of keys, used for unicast traffic. This option is disabled by default.
  • <30-86400> – Specify a value from 30 - 86400 seconds.
wpa-wpa2 psk [0 <LINE>|2 <LINE>|<LINE>]
wpa-wpa2Modifies TKIP-CCMP (WPA/WPA2) related parameters
pskConfigures a pre-shared key.
0 <LINE>Configures a clear text key
2 <LINE>Configures an encrypted key
<LINE>Enter the pre-shared key either as a passphrase not exceeding 8 - 63 characters, or as a 64 character (256bit) hexadecimal value.
wpa-wpa2 tkip-countermeasures holdtime <0-65535>
wpa-wpa2Modifies TKIP-CCMP (WPA/WPA2) parameters
tkip-countermeasuresConfigures a hold time period for implementation of TKIP counter measures
holdtime <0-65535>Configures the amount of time a WLAN is disabled when TKIP counter measures are invoked
  • <0-65535> – Specify a value from 0 - 65536 seconds. <0-65535> – Specify a value from 0 - 65535 seconds. The default is 60 seconds.
hash-to-elementEnable the use of SAE Hash-to-Element for password element generation.
