User:Haddub/Cisco 2800

The Cisco 2800 is a series of Integrated Services routers (ISR) designed and manufactured by Cisco Systems and marketed primarily to enterprise networks. They are made with a variety of chassis sizes and types, all of which share compatible card interfaces.

Routers in this series are designed to to terminate enterprise or ISP connections.

The Cisco 2800 is a line of modular routers, meaning that functionality can be added by inserting a card in a Network Module or Wan Interface slot. For most deployments a Network Module or WIC will need to be added.

Models
Cisco has released four models. The 2801 is a bare bones version of the ISR. It lacks support for Network Modules and some Advanced Integration Modules. The 2811 is a well equipped version of the ISR. It has all of the functionality of the 2821 and 2851, but has a slower processor and room for fewer network modules. The 2821 is similiar to the 2811, but features a faster processor, 2 network modules slots and Gigabit ethernet connections The 2851 is similiar to the 2851, but features 4 network modules slots.
