this box is cleared, changes will only take effect the next time the unit is
booted or the interface is reconfigured with this box ticked.
Configuration method: The drop-down menu offers the following choices:
• Static: The interface will take its address and routing parameters from
values entered by the operator.
• DHCP (Dynamic Host Configuration Protocol): The interface will
attempt to obtain its address and routing parameters from a DHCP server.
• Unconfigured but powered up (possible VLAN trunk): The interface
will not be used directly but is available for carrying virtual network
(VLAN) traffic.
• Powered off: The interface will not be used and the interface chip is
disabled, reducing the total power consumption by around 200mW.
7.1.1.2 Static IP
IP address: Only used if the Configuration method drop-down menu is set to
“Static”. The address should be entered in CIDR format, where the address is
followed by a slash and then the number of bits defining the netmask, e.g.
192.168.0.1/24 for IPV4 or 2001:db8:/32 for IPV6.
For more information about CIDR, please refer to:
http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing .
Default route (gateway): Should be populated with the IP address of the
default router. If more complicated routing configurations are required, these
can be entered in expert mode.

IP” tabs and there are three new tabs: DCHP options, IP aliasing and Routes.
