a. Optional IPv4 configuration items:
i. Set the IP metric:
(config network interface my_wan)> ipv4 metric
num
(config network interface my_wan)>
See
Configure WAN/WWAN priority and default route metrics
for further information
about metrics.
ii. Set the relative weight for default routes associated with this interface. For multiple
active interfaces with the same metric, the weight is used to load balance traffic to
the interfaces.
(config network interface my_wan)> ipv4 weight
num
(config network interface my_wan)>
iii. Set the management priority. This determines which interface will have priority for
central management activity. The interface with the highest number will be used.
(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:
n
always
: DNS will always be used for this WAN; when multiple interfaces have
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 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)>
n
See
for further information about DHCP server support for the Client
FQDN option.
