The Cisco 2811 is an integrated services router. It uses AC power, uses Cisco’s IOS IP base software, and has two PVDM slots. It provides Web routing for mostly small and medium businesses.
The device is one of the devices in the company’s state-of-the art 2800 integrated service router series. As such, it is part of Cisco’s entire integrated services router lineup which includes several other series, each series designed with a target buyer in mind.
A side-by-side comparison with previous routers manufactured by Cisco shows that the 2811 provides five times the performance and ten times the security that previous models had. Density and slot performance were boosted from previous designs.
It offers wire speed performance to allow services, such as voice and security, to run concurrently. Better modularity and performance allowed the device to provide better service to businesses and organizations.
