Parameter descriptions:
IP Configuration
Mode:
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.
DNS Server
: This setting controls the DNS name resolution done by the switch. The modes are:
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.
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.
IP Interfaces
DHCP Per Port
: The assign an IP address based on the switch port the device is connected to. This will
speed up installations of IP cameras, cameras can be configured after they are on the network.
The per-port assignment allows you to know which IP was assigned to which camera. See
Appendix A –
DHCP Per Port
on page
for more DHCP Per Port information. The parameters are:
Mode
: Disabled or Enabled. The default is Disabled.
IP
range
: Enter the assignable range (e.g., 192.168.1.78 - 192.168.1.93).
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 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.
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.
IPv4 DHCP Current Lease
: For DHCP interfaces with an active lease, this column shows the current
interface address, as provided by the DHCP server.
IPv4 Address
: 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.
IPv4 Mask Length
: 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.
IPv6 Address
: 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::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 Length
: 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.
Link-Local Address binding interface
: Configure Link-Local IP address to a different VLAN interface.
The first IP interface entry (169.254.xx.xx) is for the default value (VLAN 1).
