LABEL DESCRIPTION
Subnet Mask This field is enabled if you set the Interface Type to internal or you select Use Fixed
IP Address.
Enter the subnet mask of this interface in dot decimal notation. The subnet mask
indicates what part of the IP address is the same for all computers in the network.
Gateway This field is enabled if you select Use Fixed IP Address.
Enter the IP address of the gateway. The NXC sends packets to the gateway when it
does not know how to route the packet to its destination. The gateway should be on the
same network as the interface.
Metric This field is enabled if you set the Interface Type to external or general and select
Get Automatically.
Enter the priority of the gateway (if any) on this interface. The NXC decides which
gateway to use based on this priority. The lower the number, the higher the priority. If
two or more gateways have the same priority, the NXC uses the one that was
configured first.
IPv6 Address These IP address fields configure an IPv6 address on the interface itself.
Assignment
Enable Stateless Select this to enable IPv6 stateless auto-configuration on this interface. The interface
Address Auto-
will generate an IPv6 address itself from a prefix obtained from an IPv6 router in the
configuration
network.
(SLAAC)
Link-Local This displays the IPv6 link-local address and the network prefix that the NXC generates
Address
itself for the interface.
IPv6 Address/ Enter the IPv6 address and the prefix length for this interface if you want to use a static
Prefix Length
IP address. This field is optional.
The prefix length indicates what the left-most part of the IP address is the same for all
computers in the network, that is, the network address.
Gateway Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal
notation.
Metric Enter the priority of the gateway (if any) on this interface. The NXC decides which
gateway to use based on this priority. The lower the number, the higher the priority. If
two or more gateways have the same priority, the NXC uses the one that was
configured first.
DHCPv6 Setting
DHCPv6 Select N/A to not use DHCPv6.
Select Client to set this interface to act as a DHCPv6 client.
DUID This field displays the DHCP Unique IDentifier (DUID) of the interface, which is unique
and used for identification purposes when the interface is exchanging DHCPv6
messages with others. See
DUID as MAC Select this if you want the DUID to be generated from the interface's default MAC
address.
Customized DUID If you want to use a customized DUID, enter it here for the interface.
Enable Rapid Select this to shorten the DHCPv6 message exchange process from four to two steps.
Commit This function helps reduce heavy network traffic load.
Note: Make sure you also enable this option in the DHCPv6 server to make rapid commit
Request Address Select this to get an IPv6 address for this interface from the DHCP server. Clear this to
not get any IP address information through DHCPv6.
DHCPv6 Request If this interface is a DHCPv6 client, use this section to configure DHCPv6 request
Options settings that determine what additional information to get from the DHCPv6 server.
