CHAPTER 1
Introduction
1.1 Overview
This User’s Guide covers the following models: NXC2500 and NXC5500.
The NXC is a comprehensive wireless LAN controller. Its flexible configuration helps network
administrators set up wireless LAN networks and efficiently enforce security policies over them. In
addition, the NXC provides excellent throughput, making it an ideal solution for reliable, secure service.
The NXC’s security features include firewall and certificates. It also provides captive portal configuration,
NAT, port forwarding, policy routing, DHCP server, extensive wireless AP control options, and many other
powerful features. Flexible configuration helps you set up the network and enforce security policies
efficiently.
The front panel physical Gigabit Ethernet ports (labeled P1, P2, P3, and so on) are mapped to Gigabit
Ethernet (ge) interfaces. By default P1 is mapped to ge1, P2 is mapped to ge2 and so on.
• The default LAN IP address is 192.168.1.1.
• The default administrator login user name and password are “admin” and “1234” respectively.
1.2 Zones, Interfaces, and Physical Ports
Here is an overview of zones, interfaces, and physical ports in the NXC.
Table 1 NXC Series Comparison Table
FEATURES NXC2500 NXC5500
Link Aggregation Group (LAG) Support No Yes
Two USB Ports Yes Yes
Console Port (Serial Port) DB-9 Connector RJ-45 Connector
Table 2 Zones, Interfaces, and Physical Ethernet Ports
Zones
(LAN)
A zone is a group of interfaces. Use zones to apply security settings such as firewall.
Interfaces
(Ethernet, VLAN)
Interfaces are logical entities that (layer-3) packets pass through. Use interfaces in
configuring zones, policy routes, static routes, and NAT.
Port combine physical ports into interfaces.
Physical Ethernet Ports
(P1, P2, P3, and so on)
The physical port is where you connect a cable.

1.2.1 Interface Types
There are two types of interfaces in the NXC. In addition to being used in various features, interfaces also
describe the network that is directly connected to it.
• Ethernet interfaces are the foundation for defining other interfaces and network policies.
• VLAN interfaces recognize tagged frames. The NXC automatically adds or removes the tags as
needed. Each VLAN can only be associated with one Ethernet interface.
Note: By default, all Ethernet interfaces are placed into vlan0, allowing the NXC to function as
a bridge device.
1.2.2 Interface and Zone Configuration
This section introduces the NXC’s default zone member physical interfaces and the default
configuration of those interfaces. This section uses the NXC5500 drawings as an example.
Figure 1 Default Network Topology
Table 3 Default Interfaces Configuration
• The LAN zone contains the ge1~ ge6 interfaces (physical ports P1~P6). By default, all LAN interfaces
are put in vlan0.
• The console port is not in a zone and can be directly accessed by a computer attached to it using a
special console-to-Ethernet adapter.

1.3 Applications
These are some example applications for your NXC.
1.3.1 AP Management
Manage multiple separate Access Points (APs) from a single, persistent location. APs can also be
configured to monitor for rogue APs.
Figure 2 AP Management Example
Here, the NXC (A) connects to a number of Power over Ethernet (PoE) devices (B). They connect to the
managed Access Points (C), such as NWA5123-NI, which in turn provide access to the network for the
wireless clients (D) within their broadcast radius.
1.3.2 Wireless Security
Keep the connections between wireless clients and your APs secure with the NXC’s comprehensive
wireless security tools. APs can be configured to require WEP and WPA encryption from all wireless clients
attempting to associate with them. Furthermore, you can protect your network by monitoring for rogue
APs. Rogue APs are wireless access points operating in a network’s coverage area that are not under
the control of the network’s administrators, and can potentially open up critical holes in a network’s
security policy.
1.3.3 Captive Portal
The NXC can be configured with a captive portal, which intercepts all network traffic, regardless of
address or port, until a connecting user authenticates his or her session, through a designated login Web
page.
