Description
Configure whether the IP stack should act as a Host or a Router. In Host mode, IP traffic
between interfaces will not be routed. In Router mode traffic is routed between all
interfaces.
This setting controls the DNS name resolution done by te switch. The following modes are
supprted.
From any DHCP interfaces: The First DNS server offered from a DHCP lease to a DHCP-
enabled interface will be used.
No DNS server: No DNS server will be used.
Configured: Explicitly provide the IP address of the DNS Server in dotted decimal notation.
From This DHCP interface: Specify from which DHCP-enabled interface a provided DNS
server should be preferred.
When DNS proxy is enabled the system will relay DNS requests to the currently configured
DNS server, and reply as a DNS resolver to the client devices on the network.
Select this option to delete an existing IP interface.
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.
Enable the DHCP client by checking this box. If this option is enabled, the system will
configure the IPv4 address and mask of the interface using the DHCP protocol. The DHCP
client will announce the configured System Name as hostname to provide DNS lookup.
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.
For DHCP interfaces with an active lease, this column shows the current interface address
as provided by the DHCP server.
The IPv4 address of the interface in dotted decimal notation. If DHCP is enabled this field is
not used. The field may also be left blank if IPv4 operation on the interface is not desired.
The IPv4 network mask in number of bits (prefix length). Valid values are between 0 and
30 bits for an IPv4 address. If DHCP is enabled this field is not used. The field may also be
left blank if IPv4 operation on the interface is not desired.
The IPv6 address of the interface. An IPv6 address is in 128-bit records represented as eight
fields of up to four hexadecimal digits with a colon separating each field (:). For example,
fe80::33:33:FF:1C:A8:93. The symbol:: is a special syntax that can be used as a shorthand
way of representing multiple 16-bit groups of contiguous zeros; but it can appear only once.
It can also represent a legally valid IPv4 address. For example: 192.168.0.10. The field may
be left blank if IPv6 operations on the interface is not desired.
The IPv6 network mask, in number of bits (prefix length). Valid values are between 1 and
128 bits for an IPv6 address. The field may be left blank if IPv6 operation on the interface is
not desired.
Select this option to delete an existing IP route
The destination IP network or host address of this route. Valid format is dotted decimal
notation or a valid IPv6 notation. A default route can use the value 0.0.0.0 or IPv6 :: notation.
The destination IP network or host address of this route. Valid format is dotted decimal
notation or a valid IPv6 notation. A default route can use the value 0.0.0.0or IPv6 :: notation.
The IP address of the IP gateway. Valid format is dotted decimal notation or a valid IPv6
notation. Gateway and Network must be of the same type.
The VLAN ID (VID) of the specific IPv6 interface associated with the gateway. The given VID
ranges from 1 to 4094 and will be effective only when the corresponding IPv6 interface is
valid. If the IPv6 gateway address is link-local, it must specify the next hop VLAN for the
gateway. If the IPv6 gateway address is not link-local, system ignores the next hop VLAN for
the gateway.
