Cisco 1720 Router

The Cisco 1720 router extends the leadership established by Cisco's 1700 series routers for small businesses and small branch offices, offering more functionality and flexibility for higher-end applications. In addition to meeting the needs of Internet and intranet access, the Cisco 1720 router offers the following key advantages:

The Cisco 1720 router offers the following key components:

The flexible Cisco 1720 router supports any combination of one or two of the following WAN interface cards:

These WAN interface cards are shared with the Cisco 1600, 2600, and 3600 routers.

Cisco IOS Feature Sets for Cisco  1700 Series Routers

The Cisco  IOS software is packaged into "feature sets" (also called "software images"). There are many different feature sets available, and each feature set contains a specific subset of Cisco  IOS features. The following list shows which feature sets are supported on the Cisco 1600 series routers and access servers. These feature sets only apply to Cisco  IOS Release  12.0(1)XA:

Feature Set Tables

To determine what features are available with each feature set (software image), see Table 2. The table summarizes the features you can use when running a specific feature set on the Cisco 1700 series routers for Cisco IOS Release 12.0(1)XA. The feature set table uses the following symbol conventions to identify features:


Note This feature set table lists only new features. This table is not a cumulative or complete representation of all the features in each image. For a full list of all the features available in each image, refer to the Cisco Product Catalog.

New and Changed Information

The following sections list the new features supported by the Cisco 1700 series routers in Cisco IOS Release 12.0(1)XA.

New Features in Release 12.0(1)XA

The following new features in Cisco IOS Release 12.0(1)XA are available for the Cisco 1700 series. Release 12.0(1)XA also supports the features in Cisco  IOS Release 12.0(1)T, which are described in the Release Notes for Cisco IOS Release 12.0 T. To access this document, see the section, "Related Documentation."

Support for Cisco 1720

This is the first Cisco IOS release to include support for the Cisco 1720.

Triple DES Encryption

IPSec supports the Triple DES encryption algorithm (168-bit) in addition to 56-bit encryption. Triple DES (3DES) is a strong form of encryption that allows sensitive information to be transmitted over untrusted networks. It enables customers, particularly in the finance industry, to utilize network layer encryption.

Open Caveats---Release 12.0(1)XA

This section describes possibly unexpected behavior by Release 12.0(1)XA. This section describes only severity 1 and 2 caveats.

In addition, some caveats in Cisco IOS Releases  12.0(1) T apply to Release 12.0(1)XA. For descriptions of Cisco IOS Release 12.0 T caveats, see the Cisco IOS Software Release 12.0 T Caveats. To access this document, see the section, "Related Documentation."

Dialer Interface

If a crypto map is applied to a dialer interface, dialer pools are used, and a dialup interface (e.g., BRI) is used as the physical interface, when that dialup interface is unbound from the dialer it may cause a system reload or mis-alignments. A workaround is to not use dialer pools.

BiSYNC/BSTUN

Related Documentation
