Overview
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.

Known items that need research or verification
- Whether 837 switch can be configured with different ports in different VLANs
- Whether SVIs (VLAN interfaces) can be configured for these switch ports. (See here for blog posted who’s done it on 877: http://www.networkworld.com/community/node/27137 )
- 802.1Q trunking support on switch ports – which models
- Cisco Feature Navigator claims that IPS is supported on 837; needs to be verified.
