kerberos

Configures Kerberos authentication parameters on a WLAN. Kerberos (designed and developed by MIT) provides strong authentication for client/server applications using secret-key cryptography. Using Kerberos, a client must prove its identity to a server (and vice versa) across an insecure network connection.

Once a client and server use Kerberos to validate their identity, they encrypt all communications to assure privacy and data integrity. Kerberos can only be used on the access point with 802.11b clients. Kerberos uses NTP for synchronizing the clocks of its KDC server(s).

Supported on the following devices:

Access Points: AP3000/X, AP5010, AP310i/e, AP410i/e, AP505i, AP510i, AP510e, AP560i, AP7602, AP7612, AP7622, AP7632, AP7662, AP8163, AP8533.
Service Platforms: NX5500, NX7500, NX9500, NX9600
Virtual Platforms: CX9000, VX9000

Syntax

kerberos [password|realm|server]

kerberos password [0 <LINE>|2 <LINE>|<LINE>]

kerberos realm <REALM>

kerberos server [primary|secondary|timeout]

kerberos server [primary|secondary] host <IP/HOSTNAME> {port <1-65535>}

kerberos server timeout <1-60>

Parameters

kerberos password [0 <LINE>|2 <LINE>|<LINE>]


kerberos	Configures a WLAN's Kerberos authentication parameters The parameters are: password, realm, and server.
password	Configures a Kerberos KDC server password. The password should not exceed 127 characters. The password options are: 0 <LINE> – Configures a clear text password 2 <LINE> – Configures an encrypted password <LINE> – Specify the password.

kerberos realm <REALM>


kerberos	Configures a WLAN's Kerberos authentication parameters The parameters are: password, realm, and server.
realm <REALM>	Configures a Kerberos KDC server realm. The REALM should not exceed 127 characters.

kerberos server [primary|secondary] host <IP/HOSTNAME> {port <1-65535>}


kerberos	Configures a WLAN's Kerberos authentication parameters The parameters are: password, realm, and server.
server [primary\|secondary]	Configures the primary and secondary KDC server parameters primary – Configures the primary KDC server parameters secondary – Configures the secondary KDC server parameters
host <IP/HOSTNAME>	Sets the primary or secondary KDC server address <IP/HOSTNAME> – Specify the IP address or name of the KDC server.
port <1-65535>	Optional. Configures the UDP port used to connect to the KDC server <1-65535> – Specify the port from 1 - 65535. The default is 88.

kerberos server timeout <1-60>


kerberos	Configures a WLAN's Kerberos authentication parameters The parameters are: password, realm, and server.
timeout <1-60>	Modifies the Kerberos KDC server‘s timeout parameters <1-60> – Specifies the wait time for a response from the Kerberos KDC server before retrying. Specify a value from 1 - 60 seconds.
