CHAPTER 4
WEB OPERATION & CONFIGURATION
IP Interfaces
Click "Add Interface" to add a new IP interface. A maximum of 128 interfaces is supported.
VLAN: This is 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: When this checkbox 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.
Fallback:
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 fallback mechanism. The DHCP will keep retrying until a
valid lease is obtained when fallback is disabled. Valid value is from 0 to 4294967295.
IPv4 Address:
The IPv4 address of the interface is entered 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.
IPv4 Mask:
The IPv4 network mask is entered by a number of bits (prefix length). Valid values are between 0 and 30
bits for a 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.
IPv4 Current Lease:
For DHCP interfaces with an active lease, this column shows the current interface address, as
provided by the DHCP server.
IPv6 Address:
A IPv6 address is a 128-bit record represented as eight fields of up to four hexadecimal digits with a
colon separating each field (:). For example, fe80::215:c5ff:fe03:4dc7. 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, ::192.1.2.34. The field may be left blank if IPv6 operation on
the interface is not desired.
IPv6 Mask:
The IPv6 network mask is entered by a 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.
IP Routes
Route Network:
The IP route is 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 for IPv6 use the :: notation.
Route Mask:
The route mask is a destination IP network or host mask, in number of bits (prefix length). It defines how
much of a network address that must match, in order to qualify for this route. Valid values are between 0 and 32 bits
respectively 128 for IPv6 routes. Only a default route will have a mask length of 0 (as it will match anything).
Gateway:
This is the IP address of the gateway. Valid format is dotted decimal notation or a valid IPv6 notation.
Gateway and Network must be of the same type.
Next Hop VLAN: This field is only for IPv6 and is the VLAN ID (VID) of the specific IPv6 interface associated with the
gateway. The VID can range from 1 to 4096 and will be effective when the corresponding IPv6 interface is valid. If the
IPv6 gateway address is link-local, you must specify the next hop VLAN for the gateway. If it is not link-local, they
system ignores the next hop VLAN for the gateway.
4.3.1.4 System NTP
Setup the Network Time Protocol configuration, to synchronize this device’s clock to network time.
