Overview: 1700 Series Routers
These routers were common as branch routers during the late 1990s, and into the early 2000’s. The 1760 model does have a 19” (easily rack mountable) form factor, but the rest of the models do not easily rack mount and would need to sit on a shelf. Several models support later IOS versions. To allow use as a branch router that uses the Internet for connectivity back into the Enterprise, several models support advanced security features for CCNA Security preparation. The routers support WICs as well.

1700 Series Hardware
The 1720 and 1721 models have particular appeal for certifcation in that they support 2 WIC-2T slots, for up to 4 serial interfaces, plus a 10/100 interface that supports 802.1Q. The 1760 has the advantage of support for 2 Voice Interface Cards (VICs) that can be useful when working towards CCNA Voice or CCVP.

Notes and Advice
- The 10/100 ports on all the above models support 802.1Q trunking.
- The 1720/1721 use an external power supply (power brick). When purchasing used, make sure the router comes with the power cord and transformer.
- The 1710 was not considered when creating this page. It has several differences, including a latest IOS of 12.4 mainline (not 12.4T).
