Chapter 1 Product Overview
1.1 Introduction
H3C AR 18-2X Series Routers (hereinafter referred to as the AR 18-2X series) are Ethernet access routers designed for small office home office (SOHO) subscribers. By far, the series have six models: AR 18-21/18-22/18-22-8/18-22S-8/18-23-1/18-23S-1. They provide an uplink Ethernet interface and four downlink layer 2 (L2) switched 10/100BASE-T Ethernet interfaces that can be isolated.
The AR 18-2X series support multiple virtual private network (VPN) services, such as layer 2 tunneling protocol (L2TP) VPN, IP security (IPSec) VPN, generic routing encapsulation (GRE) VPN, and dynamic VPN (DVPN). They can provide tunnel connections to remote users to build VPNs that can be internets, intranets, or access networks.
The series support firewall, AAA (authentication, authorization, accounting), network address translation (NAT), and quality of service (QoS). Therefore, they can ensure security and guaranteed services to the private networks constructed on the open Internet.
In the series the AR 18-22S-8 and AR 18-23S-1 has a build-in hardware encryption chip, which can significantly improve encryption performance.
The interfaces that the AR 18-2X series provide are compliant with the international standards and can work with the products of other vendors at every layer. The existing investment of users can thus be protected to the maximum.
