Configuring Controllers and Interfaces: Port VLAN Overview
7-15
Port VLAN Overview
The port VLAN feature provides the capability to group ports together such that they
operate as separate network segments. Packets are tagged using the IEEE 802.1Q
standard for Ethernet tagging.
Application
Figure 7-2 shows a typical application of port based VLANs. Networks A, B and C are
located on either side of a Connect and a Remote RMX-3200. The traffic on each
network is segregated from the other networks, then bundled and sent over a
common link between Connect and Remote RMX-3200. The networks may or may
not have overlapping IP network addresses. To provide the isolation of the networks,
packets traversing common network links are tagged with an identifier for their
particular network.

Port Modes
In Remote RMX-3200, there is a single bridge controller. Ports connected to a bridge
controller can be in one of three modes: native, port VLAN, or trunk.
Native Mode
A port in native mode transmits and receives all traffic without modifying any 802.1Q
tags. Traffic received that has a tag which is used by a port VLAN is dropped. All
other traffic received by a native mode port is forwarded to other native mode ports
and trunk ports.
