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.
IPv4 DHCP Client Identifier Type
The type of DHCP client identifier. User can choose Auto, ifmac, ASCII, and HEX.
IPv4 DHCP Client 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 Client 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 Client 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 shows the current interface address, as provided by
the DHCP server.
