The LCS60 has a physical IP network number for its Ethernet interface (e.g., 154.12.21) and can have a virtual IP network number for each defined security group (e.g., Library, morse, Techs, Eng), up to a maximum of four such groups as shown in Figure 1-4.

Note: The Ethernet IP network number and the four virtual IP network numbers must be unique.

The LCS60 examines the destination address of every IP packet it receives over the Ethernet and CommKit Host interfaces, and sends the packet on to the LAN segment it matches. For this reason, all network numbers must be unique. For example, for an IP packet with a destination address 154.12.24.50, the LCS60 morse would route the packet through LAN segment Library as shown in Figure 1-4.
