(config network interface my_wan)> ipv4 mgmt num
(config network interface my_wan)>
iv. Set the MTU:
(config network interface my_wan)> ipv4 mtu num
(config network interface my_wan)>
v. Configure how to use DNS:
(config network interface my_wan)> ipv4 use_dns value
(config network interface my_wan)>
where value is one of:
vi. Enable DHCP Hostname to instruct the IX20 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)>
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 ?
