DESCRIPTION
Select this option to have the NXC enforce links between specific IP addresses and
specific MAC addresses for this VLAN. This stops anyone else from manually using a
bound IP address on another device connected to this interface. Use this to make use
only the intended users get to use specific IP addresses.
Select this option to have the NXC generate a log if a device connected to this VLAN
attempts to use an IP address that is bound to another device's MAC address.
Configure a list of static IP addresses the NXC assigns to computers connected to the
interface. Otherwise, the NXC assigns an IP address dynamically using the interface's
IP Pool Start Address and Pool Size.
Click this to create a new entry.
Select an entry and click this to be able to modify it.

Enter a description to help identify this static DHCP entry. You can use alphanumeric
and ()+/:=?!*#@$_%- characters, and it can be up to 60 characters long.
The NXC can regularly check the connection to the gateway you specified to make sure
it is still available. You specify how often to check the connection, how long to wait for a
response before the attempt is a failure, and how many consecutive failures are
required before the NXC stops routing to the gateway. The NXC resumes routing to the
gateway the first time the gateway passes the connectivity check.
Select this to turn on the connection check.
Select the method that the gateway allows.
Select icmp to have the NXC regularly ping the gateway you specify to make sure it is
still available.
Select tcp to have the NXC regularly perform a TCP handshake with the gateway you
specify to make sure it is still available.
Enter the number of seconds between connection check attempts.
Enter the number of seconds to wait for a response before the attempt is a failure.
Enter the number of consecutive failures before the NXC stops routing through the
gateway.
Select this to use the default gateway for the connectivity check.
Select this to specify a domain name or IP address for the connectivity check. Enter
that domain name or IP address in the field next to it.
This field only displays when you set the Check Method to tcp. Specify the port
number to use for a TCP connectivity check.
Click OK to save your changes back to the NXC.
