where value is one of:
n

the same DNS server, the interface with the lowest metric will be used for DNS
requests.
n
primary: Only use the DNS servers provided for this interface when the
interface is the primary route.
n
never: Never use DNS servers for this interface.
vi. Enable DHCP Hostname to instruct the IX30 device to include the device's system
name with DHCP requests as the Client FQDN option. The DHCP server can then be
configured to register the device's hostname and IP address with an associated DNS
server.
(config network interface my_wan)> ipv4 dhcp_hostname true
(config network interface my_wan)>
n
See RFC4702 for further information about DHCP server support for the Client

See Configure system information for information about setting the IX30

b. See Configure SureLink active recovery to detect WAN/WWAN failures for information
about configuring SureLink for active recovery.
7. (Optional) Configure IPv6 settings:
a. Enable IPv6 support:
(config network interface my_wan)> ipv6 enable true
(config network interface my_wan)>
b. Set the IPv6 type to DHCP:
(config network interface my_wan)> ipv6 type dhcpv6
(config network interface my_wan)>
c. Generally, the default settings for IPv6 support are sufficient. You can view the default IPv6
settings by using the question mark (?):
(config network interface my_wan)> ipv6 ?
