VLAN Support On Routers

I recently bought an 851 only to find out afterwards that it only supports 1 VLAN when I needed it to support at least 7. The documentation on VLAN support seemed pretty buried.

Does anyone know if there is an easy way to find out how many VLANs each router model supports? I dont' want to make the same mistake again, and I can't seem to find what I'm looking for by combing through the data sheets for each model.


Sorry, I meant to post this in the routing and switching forum and I can't figure out how to delete the thread.


Re: VLAN Support On Routers

Why do you say the 851 only supports one VLAN? I think you may have some configuration issues, because it will support your 7 VLANs.

Re: VLAN Support On Routers


A maximum of four VLANs are supported on the Cisco 870 Series with the plus feature set (Advanced IP Services/Advanced Enterprise Services) Cisco IOS. The Cisco 850 Series only supports one 802.1q VLAN.
