Chapter 11 Interfaces Table 63 Configuration > Network > Interface > Ethernet > Edit (continued) LABEL DESCRIPTION First DNS Server, Second DNS Server, Third DNS Server Specify the IP addresses up to three DNS servers for the DHCP clients to use. Use one of the following ways to specify these IP addresses. Custom Defined - enter a static IP address. From ISP - select the DNS server that another interface received from its DHCP server. NXC - the DHCP clients use the IP address of this interface and the NXC works as a DNS relay. First WINS Server, Second WINS Server Type the IP address of the WINS (Windows Internet Naming Service) server that you want to send to the DHCP clients. The WINS server keeps a mapping table of the computer names on your network and the IP addresses that they are currently using. Lease time Specify how long each computer can use the information (especially the IP address) before it has to request the information again. Choices are: infinite - select this if IP addresses never expire. days, hours, and minutes - select this to enter how long IP addresses are valid. Enable IP/MAC Binding Select this option to have this interface enforce links between specific IP addresses and specific MAC addresses. 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.
