Can I configure ethernet sub-interfaces on a 1921 or 2600?

Have just tried setting up a lab to test a possible office setup.
I have been trying to configure a Cisco 2600 with subinterfaces to connect to switch.

What I have is:
C2600 Software (C2600-I-M), Version 12.3(26), RELEASE SOFTWARE (fc2)

What I am trying to do is:

Interface Ethernet 0/0.10
ip address 192.168.1.1 255.255.255.0
encapsulation dot1q

Interface Ethernet 0/0.20
192.168.2.1 255.255.255.0
encapsulation dot1q

etc....

The Interface Ethernet 0/0 will be patched into a downstream Cisco 3960G with VLANs for each subinterface

My issues that when i try to configure an IP address it tells me:

% Configuring IP routing on a LAN subinterface is only allowed if that
subinterface is already configured as part of an IEEE 802.10, IEEE 802.1Q,
or ISL vLAN.


I look at the list of allowed commands on the interface and trunk encapsulation is not actually listed.

Do I need to buy an IPServices license for this to work?

I am actually planning on setting up a small office with a similar setup using a Cisco 1921 Integrated Services router. Will this work with 1921 IP Base?

Did you put this in before the config you listed

Interface Ethernet 0/0
no shut

then the bit you listed

 

Oh sorry you should also set the dot1Q before the ip address on the sub interface.

 

me again after the dot1q you need to add the vlan its part of as part of the same statement.

eg vlan 10 would look like this

encap dot1q 10

Here is a link to a cisco resource on the subject

http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtunvlan.html

 

try this

Interface Ethernet 0/0
no shut

Interface Ethernet 0/0.10
encapsulation dot1q 10
ip address 192.168.1.1 255.255.255.0

Interface Ethernet 0/0.20
encapsulation dot1q 20
192.168.2.1 255.255.255.0

 

Hey, thanks for the reply. Yes I enabled Ethernet 0/0 before I tried to configure anything on the subinterfaces.
When I "?" for a list of commands, there is no "encapsultation" option there, nor is there any other command for anything similar.
I just logged onto a cisco 2811 and tried the same thing and had no issues. If i do a show ver this is what I have:
Cisco IOS Software, 2801 Software (C2801-SPSERVICESK9-M), Version 12.4(24)T3, RELEASE SOFTWARE (fc2)

On the 2600 if i do a show ver i get this:
C2600 Software (C2600-I-M), Version 12.3(26), RELEASE SOFTWARE (fc2)

 

Ok mate, go here and you will be able to see exactly what your IOS supports

Hey,
Thanks for the tip. I just found out that you cannot run 802.1Q without at least IP Plus...
I have already ordered a couple of 1921's with IP Base...
does this just mean that I need to purchase the license upgrade keys from Cisco?

 

According to the cisco feature navigator a 1921 with ios universal ip base will support ieee 802.1q vlan support & trunking.

 

Excellent!
Im not sure how I missed that when i looked at the feature navigator. I just jumped in again now and found it.
Thanks very much for your help.

 

Hi, i'm attempting to set up trunking 801Q on a 2621 router with software version 11.3 (2) XA4. Looks like this IOS does not support trunking according to the Cisco feature tool mentioned in an earlier post. How do I/or where can i download a newer IOS for my router to enable trunking it it's sub interfaces?
