Overview: 800 Series Routers

Cisco has introduced many routers whose product numbers sit inside the 800 series range. Cisco would occasionally add new router models, and move others to End-of-Sale (EOS) status. So, it’s a little harder to look at this model series and figure out which are the older (and possibly cheaper used) models, and which are newer.

The earlier models were mainly intended for smaller Enterprise branch offices and Small Office Home Office (SOHO) use. The earlier models typically did not support serial WICs, instead using DSL or cable for the wireless uplinks.

This document focuses on three models popular in the used market: 837, 857, and 877.
