Still searching - encapsulation not valid?

My 3810 router - which is way better than my 2600 - doesn't seem to be able to do encapsulation commands. Here's what happens:
(config)#int e0.1
(config-if)#encapsulation dot1q 2
% Invalid input detected at '^' marker.
When I do this command to check...
(config-if)#?
...the list of commands that come up don't list anything about "encapsulation." Does this mean I can't hook up different devices to my switch - going to my 3810 router - and have them in different vlans? I have a laptop and two IP phones, and I want to separate the voice from the data. I can do it fine with my 2600 router, but it's just a bare-bones router. I called Cisco, but they said since my ebay router isn't under warranty, they can't answer my question(!) I'm methodically going through the forums, trying to find an answer to this question. No success yet. Nowhere else to turn, either.
I'm not trying to do frame-relay - I just want to create some sub-interfaces, which I can do, but it refuses to go further without an encapsulation command. Here's what I wanted to do:
(config)#int e0.2
(config-if)#encapsulation dot1q 2
(config-subif)#ip address 10.2.0.1 255.255.255.0
(config-subif)#int e 0.20
(config-subif)#encapsulation dot1q 20 native
(config-subif)#ip address 10.20.0.1 255.255.255.0
(config-subif)#int e 0.25
(config-subif)#encapsulation dot1q 25
(config-subif)#ip address 10.25.0.1 255.255.255.0
(config-subif)#int e 0
(config-subif)#exit
(config-if)#no shut
(config)#int e0.1
(config-if)#encapsulation dot1q 2
% Invalid input detected at '^' marker.

Looks like you are out of luck as far as 802.1Q trunking on the MC3810. You can search through the Cisco Feature Navigator but a quick search didn't show any support for 802.1Q trunking on the MC3810 for me.An expert is a man who has made all the mistakes which can be made. -

I thought the problem might be that I have merely an ethernet port - not a fast ethernet port? I find it hard to believe that a high-powered voice router can't do simple encapsulation on its LAN interface. -

I wouldn't call the MC3810 "high powered." They have been EOL/EOS since 2005.An expert is a man who has made all the mistakes which can be made.

Check your IOS version. Some will say that command is available but do not support it.BIT - Network Administration

A MC3800 isn't the same as a current model ISR 3800. Unless you need the voice abilities built into the MC3800, I'd use the 2600/2600XM over it.

The MC3810 focuses all its power on the Voice Side -- the 2600 is still better for routing. The "bigger" VG200 Voice Gateway doesn't even support WAN connections.Computer idiot wrote: »I find it hard to believe that a high-powered voice router can't do simple encapsulation on its LAN interface.
Why don't you let the 2600 do the Inter VLAN routing, But remember, the 2600 couldn't even do it until the 12.2 ( 8 )T IP Plus release.Computer idiot wrote: »My 3810 router - which is way better than my 2600:mike: Cisco Certifications -- Collect the Entire Set!
