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.
