2-4 CHAPTER 2: VLANS ON THE LANPLEX® SYSTEM
Switch Ports
A group of switch ports is any combination of switch ports on the LANplex
system. Included are switch ports created as ATM LAN Emulation Clients
(ATM LECs). VLANs do not support media implementations that do not run
over switch (bridge) ports, for example, ATM Logical IP Subnets (ATM LISs).
Layer 3 Addressing Information
For IP VLANs only, the LANplex system optionally supports configuring of
individual IP VLANs with network layer subnet addresses. With this
additional layer 3 information, you can create independent IP VLANs that
share the same switch ports for multiple IP VLANs. Data is flooded according
to both the protocol (IP) and the layer 3 information in the IP header to
distinguish among multiple IP VLANs on the same switch port. This
configuration is discussed later in the section “Overlapped IP VLANs.”
