Hardware VPN Encryption Module

All Cisco 1700 models are equipped with an internal expansion slot to support an optional ﬁeld-installable hardware

VPN encryption module. The VPN encryption module ofﬂoads encryption processing from the Cisco 1700 Series

RISC processor, providing performance up to T1/E1 speeds. The VPN encryption module (MOD1700-VPN)

supports a maximum of 100 remote access tunnels.

Cisco IOS Software Feature Sets

Cisco 1721 and 1720 routers support a full range of Cisco IOS features, including multiprotocol routing, QoS, VPN,

ﬁrewall/IDS, and legacy IBM protocol and applications in use today.

The Cisco 1721 and 1720 routers are shipped with the base Cisco IOS feature sets supporting IP routing and

standards such as Network Address Translation (NAT), Open Shortest Path First (OSPF), RADIUS, Remote

Monitoring (RMON), VLAN routing, basic QoS feature (Weighted Fair Queing), and Next Hop Resolution Protocol

[NHRP]).

Cisco IOS IP Plus feature sets contain L2TP, L2F, Border Gateway Protocol (BGP), IP multicast, Frame Relay

switched virtual circuit (SVC), RSVP, PPP over Ethernet client, NetFlow, the Netware Link Services Protocol (NLSP),

Simple Multicast Routing Protocol (SMRP), the Web Cache Control Protocol (WCCP), and the Network Timing

Protocol (NTP). In addition, enhanced QoS features are also supported (LLQ, FRTS, RSVP, CEF, WRED, DiffServ,

MLPP with LFI).

IPSec encryption is offered in special encryption feature sets (Plus IPSec 56 and Plus IPSec 3DES). To build an IP VPN,

the recommended feature sets are IP/Firewall Plus IPSec 56 or IP/Firewall Plus IPSec 3DES.

For a detailed list of features and memory requirements for a given feature set, see Cisco IOS 1700 Release Notes.

Network Management and Installation Tools

The Cisco 1721 and 1720 support a range of network-management and ease-of-installation tools.

CiscoWorks2000, the industry-leading Web-based network management suite, provides the ability to remotely

conﬁgure, administer, monitor, and troubleshoot the Cisco 1721 and 1720; and increased visibility into network

behavior to quickly identify performance bottlenecks and long-term performance trends. It also provides

sophisticated conﬁguration tools to optimize bandwidth and utilization across expensive and critical WAN links in

the network.

CiscoView, part of CiscoWorks2000, is a Web-based tool that graphically provides real-time status of the Cisco 1721

and 1720. It can drill down to display monitoring information on interfaces and provide dynamic status, statistics,

and comprehensive conﬁguration information.

CiscoWorks Small Network Management Solution (SNMS) is a comprehensive, Web-based network management

solution that provides a powerful set of monitoring, conﬁguration, and management tools to simplify the

administration of small to medium business networks and workgroups that contain up to 20 Cisco internetworking

products (switches, routers, hubs, and access servers). CiscoWorks SNMS is an ideal solution for companies that need

server monitoring and network management from a single application to optimize performance and maximize

network productivity. With CiscoWorks SNMS, Cisco provides a cost-effective and user-friendly solution that helps

Cisco customers make the optimal use of their resources. The solution provides the following:
