From this DHCPv4 interface: Specify from which DHCPv4‐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.
From this DHCPv6 interface: Specify from which DHCPv6‐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. Note: Only IPv4 DNS proxy is currently
supported.
IP Interfaces
DHCP Per Port Mode: Enable/Disable DHCP per port.
DHCP Per Port IP: Define the IP range for DHCP per port. The DHCP Per Port IP range must equal the switch TP
port number (24 for the SM24TAT4XB or 48 for the SM48TAT4XA‐RP).
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.
IPv4 DHCP Clinet Identifier Type: The DHCP Client identifier per IETF RFC 4361.
IPv4 DHCP Clinet Identifier IfMac: The interface name of DHCP client identifier. When DHCPv4 client is enabled
and the client identifier type is 'ifmac', the configured interface's hardware MAC address will be used in the DHCP
option 61 field.
IPv4 DHCP Clinet Identifier ASCII: The ASCII string of DHCP client identifier. When DHCPv4 client is enabled and
the client identifier type is 'ascii', the ASCII string will be used in the DHCP option 61 field.
IPv4 DHCP Clinet Identifier HEX: The hexadecimal string of DHCP client identifier. When DHCPv4 client is enabled
and the client identifier type 'hex', the hexadecimal value will be used in the DHCP option 61 field.
IPv4 DHCP Hostname: The hostname of DHCP client. If DHCPv4 client is enabled, the configured hostname will be
used in the DHCP option 12 field. When this value is empty string, the field uses the configured system name plus
the latest three bytes of system MAC addresses as the hostname.
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 show 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
configures the fallback address. The field may be left blank if IPv4 operation on the interface is not desired ‐ or no
DHCP fallback address is desired.
IPv4 Mask: 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 configures the fallback address network mask. The field may be left
blank if IPv4 operation on the interface is not desired ‐ or no DHCP fallback address is desired.
