VPN and Security

The Cisco 1760 router is part of the end-to-end Cisco VPN solution. VPNs create secure connections via the Internet to connect geographically dispersed offices, business partners, and remote users while providing security, traffic prioritization, management, and reliability equal to that of private networks.

By supporting industry standards IPSec, L2TP, and DES and 3DES, the Cisco 1760 router delivers robust VPN solutions to ensure data privacy, integrity, and authenticity.

The optional Cisco VPN Hardware Encryption Module for the Cisco 1760 router further optimizes VPN encryption performance. By offloading encryption tasks to the VPN module, the router processor is freed up to handle other operations. The VPN module accelerates the rate at which encryption occurs, speeding the process of transmitting secure data—a critical factor when using 3DES encryption.

The Cisco 1760 router offers integrated security features, including stateful inspection firewall functionality and IDS as an optional Cisco IOS Software feature. By deploying Cisco IOS Software firewall functionality, customers do not need to purchase or manage multiple devices, thus simplifying network management and reducing capital costs. Additionally, remote management applications, such as Cisco Security Device Manager (SDM), make it easier than ever to deploy and monitor VPN and Cisco IOS Firewall on your Cisco 1760 router.

Cisco IOS Software firewall security features include access control lists (ACLs) and user authentication, authorization, and accounting (such as PAP/CHAP, TACACS+, and RADIUS). These security features provide the optimal level of firewall protection to customers.

Voice Implementation

The Cisco 1760 Modular Access Router supports FXO, FXS, E&M, ISDN BRI VICs, and T1/E1 multiflex V/WICs.

The FXO interface allows an analog connection to the central office of the Public Switched Telephone Network (PSTN). The FXS interface connects basic telephone service phones (home phones), fax machines, key sets, and PBXs through ring voltage and dial tone. The E&M interface allows connection for PBX trunk lines (tie lines). The ISDN-BRI NT/TE VIC is used to connect to the PSTN or a PBX/KTS, whereas the T1/E1 multiflex V/WIC (multiflex V/WIC) supports both data and voice services.

The multiservice-ready Cisco 1760-V router version includes all the features needed for immediate integration of data and voice services:

  • One DSP—support for up to two voice channels
  • 32-MB Flash memory
  • 96-MB DRAM
  • Cisco IOS IP/Voice Plus feature set

VICs and WICs are available separately.

The Cisco 1760 and Cisco 1760-V routers have two DSP module slots on the motherboard, each of which supports a DSP module with up to five DSPs to allow additional voice-channel support. A maximum of ten DSPs are supported.

DSP Requirements

Cisco 1760 series routers support 3 types of DSP images: high complexity (HC), medium complexity (MC) and Flexi-6. HC and MC are used for analog1 VICs; Flexi-6 is used for T1/E1 VWICs2 and BRI VIC. MC is introduced in Cisco 1760 series starting from Cisco IOS 12.2(8)YN release, which will merge into 12.3(2)T. Therefore, please make sure to use Cisco 12.2(8) YN or later releases when using MC. In addition, starting from 12.2(8)YN release, the default DSP image for BRI VIC is changed from HC to Flexi-6. BRI VIC cannot be configured to HC or MC through CLI, however. If any DSP resources used for analog are left, BRI VIC can automatically take use of those resources by using HC or MC.Table 8 lists the default images for each type of VICs; Table 9 lists IOS support for each DSP image. Table 10 lists the number of channels supported by one DSP (PVDM-256K-4) for each codec type.

Please use the following rules for calculating DSP requirements on the Cisco 1760 series routers:

1. For 12.2T releases:

  • a. Each 2-port analog VIC requires 1 DSP (PVDM-256K-4)
  • b. Each VIC-2BRI-NT/TE requires 2 DSPs (PVDM-256K-8)
  • c. For VWICs, refer to Table 10. For example, 12 G.711 digital T1/E1 voice calls require two DSPs; 12 G.729 calls require four DSPs
  • d. Total DSP requirement is the sum of a, b and c. The DSP resources can not be shared between analog VICs and VWICs

2. For the Early Deployment (ED) releases: Cisco IOS 12.2(8)YN or later (Note: not include 12.2(11)YT) or 12.3T train releases or later, please always refer to the DSP Calculator in the following link:

http://www.cisco.com/pcgi-bin/Support/DSP/cisco_prodsel.pl

The DSP calculator optimizes the DSP resources for your configuration and suggests CLI configurations.

Cisco IOS Technology

The Cisco 1760 Modular Access Router benefits from the power of Cisco IOS Software. For example, through Cisco IOS Software, the Cisco 1760 router delivers QoS capabilities, including RSVP, WFQ, CAR, and DSCP Precedence.

These features enable businesses to prioritize traffic on their networks by user, application, traffic type, and other parameters to ensure that business-critical data and delay-sensitive voice are appropriately prioritized.

Further, for businesses that are increasingly accessing the Internet via DSL, QoS features are necessary to ensure highest voice quality. For DSL services with QoS features, the Cisco 1760 router can be deployed with the ADSL or the G.shdsl WAN Interface Card.

The advanced DSL QoS features include the following:

  • LFI using MLP over ATM
  • Low-latency queuing (also called PQ/CBWFQ)
  • Weighted Random Early Detection (WRED)
  • Committed Access Rate (CAR)
  • Differentiated services (DiffServ) (class-based marking)

Cisco IOS Software Feature Sets

The Cisco 1760 router supports a choice of Cisco IOS Software feature sets with rich data features as well as a combined data and voice feature set. Tables 10 and 11 list these feature sets, including the memory requirements.

Network Management and Ease-of-Installation Tools

The Cisco 1760 router supports a range of network-management and ease-of-installation tools.

Cisco Security Device Manager (SDM) is an intuitive, web-based device management tool embedded within the Cisco IOS access routers. SDM simplifies router and security configuration through smart wizards to enable customers to quickly and easily deploy, configure and monitor a Cisco access router without requiring knowledge of Cisco IOS Command Line Interface (CLI). For more information visit http://www.Cisco.com/go/sdm .

Cisco ConfigMaker is a Microsoft Windows wizard-based tool designed to configure a small network of Cisco routers, switches, hubs, and other network devices from a single PC. This tool makes it easy to configure value-add security features such as the Cisco IOS Firewall feature set, IPSec encryption, Network Address Translation (NAT), the Dynamic-Host-Configuration-Protocol (DHCP) server, and to establish VPN policies (including QoS and security).

Cisco ConfigMaker 2.6 is supported on the Cisco 1760 Modular Access Router.

CiscoView, a member of the CiscoWorks2000 Family, is a Web-based device-management application that provides dynamic status, monitoring, and configuration information for the broad range of Cisco internetworking products. CiscoView displays a physical view of a device chassis, with color-coding of modules and ports for at-a-glance status. Monitoring capabilities display performance and other statistics. Configuration capabilities allow comprehensive changes to devices, given that requisite security privileges are granted.

Additional features include:

  • Real-time monitoring of key information that relates to device performance, traffic, and usage, with metrics such as utilization percentage, frames transmitted and received, errors, and a variety of other device-specific indicators
  • The ability to change device configurations such as IP route, VLAN, and duplex settings
  • On-demand access to Cisco.com, Cisco's Web site, for new and updated device support
  • A Web-based application that allows multiuser access to a single CiscoView server

CiscoView is supported on the Cisco 1760 router.

CiscoWorks 2000 Resource Manager Essentials, a member of the CiscoWorks2000 family of network management products, is a powerful suite of Web-based applications offering network management solutions for Cisco switches, access servers, and routers. The Resource Manager Essentials browser interface allows easy access to information critical to network uptime and simplifies time-consuming administrative tasks. The Management Connection feature in Resource Manager Essentials adds Web-level integration of other management tools from Cisco and partner companies, thereby enabling utilization of these tools and applications to create a seamless, central point of network administration. Comprising six applications and optional add-on packages such as CiscoWorks for Switched Internetworks Campus, Resource Manager Essentials includes:

  • Inventory Manager
  • Change Audit
  • Device Configuration Manager
  • Software Image Manager
  • Availability Manager
  • Syslog Analyzer
