Use Interface to select the interface for which data is to be displayed or configured. 2. Use Secondary IP Address to add a secondary IP address to the selected interface. 3. Use Secondary IP Subnet Mask to enter the subnet mask for the interface. This is also referred to as the subnet/network mask, and defines the portion of the interface's IP Address that is used to identify the attached network. This value is read only once configured. 4. Click ADD to add a Secondary IP Address for the selected interface. 5. Click DELETE to delete the Secondary IP Address from the selected interface. Table 12. Field VLAN ID Primary IP Address Description The VLAN ID associated with the displayed or configured interface. The Primary IP Address for the Interface. IPv6 IPv6 is the next generation of the Internet Protocol. With 128-bit addresses, versus 32-bit addresses for IPv4, IPv6 solves the address depletion issues seen with IPv4 and removes the requirement for Network Address Translation (NAT), which is used in IPv4 networks to reduce the number of globally unique IP addresses required for a given network. Its aggregate addresses can dramatically reduce the size of the global routing table through well known address combinations. Security is more integrated and network configuration is simplified yet more flexible. IPv6 can coexists with IPv4. As with IPv4, IPv6 routing can be enabled on physical and VLAN interfaces. Each L3 routing interface can be used for IPv4, IPv6, or both. IP protocols running over L3 (for example, UDP and TCP) do not change with IPv6. For this reason, a single CPU stack is used for transport of both IPv4 and IPv6, and a single sockets interface provides Chapter 4. Routing | 229
