Configured IPv4
Explicitly provide the valid IPv4 unicast address of the DNS Server in dotted decimal notation.
Make sure the configured DNS server could be reachable (e.g. via PING) for activating DNS
service.
•
From this DHCPv4 interface
Specify from which DHCPv4-enabled interface a provided DNS server should be preferred.
•
Configured IPv6
Explicitly provide the valid IPv6 unicast (except linklocal) address of the DNS Server.
Make sure the configured DNS server could be reachable (e.g. via PING6) for activating DNS
service.
•
From this DHCPv6 interface
Specify from which DHCPv6-enabled interface a provided DNS server should be preferred.
•
From any DHCPv6 interfaces
The first DNS server offered from a DHCPv6 lease to a DHCPv6-enabled interface will be used.
DNS Proxy
When DNS proxy is enabled, system will relay DNS requests to the currently configured DNS server, and
reply as a DNS resolver to the client devices on the network.
Only IPv4 DNS proxy is now supported.
IP Interfaces
Delete
Select this option to delete an existing IP interface.
VLAN
The VLAN associated with the IP interface. Only ports in this VLAN will be able to access the IP
interface. This field is only available for input when creating a new interface.
IPv4 DHCP Enabled
Enable the DHCPv4 client by checking this box. If this option is enabled, the system will configure the
IPv4 address and mask of the interface using the DHCPv4 protocol. The DHCPv4 client will announce
the configured System Name as hostname to provide DNS lookup.
IPv4 DHCP Fallback Timeout
The number of seconds for trying to obtain a DHCP lease. After this period expires, a configured IPv4
address will be used as IPv4 interface address. A value of zero disables the fallback mechanism, such that
DHCP will keep retrying until a valid lease is obtained. Legal values are 0 to 4294967295 seconds.
