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.

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.
