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 providetunnel 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.
