subnet as the thin client as defined by the IP address and the subnet mask. If DHCP is used, the address can be
supplied through DHCP.
d. Select the IPv6 check box, and then click Advanced to select various IPv6 supported setting options from the available
check boxes.
The following check boxes are displayed in the IPv6 Advanced Settings dialog box:
● Allow IPv4 to be disabled when IPv6 is enabled
● Prefer IPv4 over IPv6 when both are available
● Disable Stateless Address autoconfiguration (SLAAC)
● Disable Duplicate Address Detection (DAD)
● Disable ICMPv6 Echo Reply
●
Disable ICMPv6 Redirect Support
● Use Standard DHCPv6 timers
Click Properties, and use the following guidelines:
● Wait DHCP—Select this option to enable your thin client to consider IPv6 DHCP before you log in. If you do not
select this option, and DHCP is enabled, the system still waits for IPv4 DHCP.
● Dynamically allocated over DHCP/BOOTP—Select this option to enable your thin client to automatically receive
information from the DHCP server. The network administrator must configure the DHCP server (using DHCP options)
to provide information. Any value that is entered locally in the Options tab is replaced by the DHCP value. If the
DHCP server fails to provide replacement values, the locally entered value is used.
● Statically specified IP Address—Select this option to manually enter the IP address, subnet mask, and default
gateway.
○ IP Address—Enter a valid network address in the server environment. The network administrator must provide
this information.
○ Subnet Prefix Len—Enter the prefix length of the IPv6 subnet.
○ Default gateway—Use of gateways is optional. For more information, see various IPv4-supported options in this
section.
● DNS servers—Use of DNS is optional. DNS allows you to specify remote systems by their host names rather than IP
addresses. If a specific IP address (instead of a name) is entered for a connection, it rather than DNS is used to make
the connection. Enter the network address of an available DNS server. The value for this box may be supplied by a
DHCP server. If the DHCP server provides this value, it replaces any locally configured value. If the DHCP server does
not provide this value, the locally configured value is used.
NOTE:
If you enable IPv6 for both ENET0 and ENET1, IPv6 routes through the Ethernet connection that fetches
the IPv6 address first.
e. Select the Enable the IEEE802.1x authentication check box, and from the EAP type drop-down list, select TLS,
LEAP, PEAP or FAST.
● TLS—Select this option, and click Properties to configure the Authentication Properties dialog box.
○ Select the Validate Server Certificate check box because it is mandatory to validate your server certificate.
NOTE:
The CA certificate must be installed on the thin client. The server certificate text field supports a
maximum of approximately 255 characters, and supports multiple server names.
○ Select the Connect to these servers check box, and enter the IP address of server.
○ Click Browse to find and select the client certificate file and the private key file you want.
NOTE: Ensure that you select the PFX file only.
○ From the Authenticate drop-down list, select either user authentication or machine authentication that is based
on your choice.
The following kinds of server names are supported—all examples are based on Cert Common name
company.dell.com:
￭ *.dell.com
￭ *dell.com
￭ *.com
NOTE:
Using only the FQDN, that is, company.dell.com does not work. Use one of the options, for example
servername.dell.com (*.dell.com is the most common option as multiple authentication servers may
exist).
● LEAP—Select this option, and click Properties to configure the Authentication Properties dialog box. Be sure to
use the correct username and password for authentication. The maximum length for the username or the password is
31 characters.
