How do you create a Serial Subinterface on a Cisco 2811 router. This is for a WAN lab. I have a another Cisco 2811 router that was preconfigured with the serial subinterface withe following IOS flash:c2800nm-ipbase-mz.124-3g.bin. The Cisco 2811 router that I'm unable to create a subinterface on has the follwoing IOS flash:c2800nm-advsecurityk9-mz.124-15.T9.bin. i'm not sure if the IOS is the problem or I'm usign the wrong commands.
RTR2(config)#interface serial 2/0.10 ^ % Invalid input detected at '^' marker.
RTR2(config)#inter RTR2(config)#interface serial 0/0/0 ^ % Invalid input detected at '^' marker.

I believe that it is very unlikely that your problem is related to the version of IOS. I suspect that the issue is in the approach to configuring the serial subinterface.
Note that some serial interface encapsulations (such as Frame Relay) do support subinterfaces while others (HDLC and PPP) do not support subinterfaces.
It would be helpful is you could post the configuration of the serial interface and the serial subinterface from the router that was supplied to you. And it would be helpful if you also post the exact commands that you are entering and any response generated from the router when you attempt the configuration of the serial subinterface.
When the sh run command is executed a serial interface is not displayed. This particular post said, the T1 Controller interface need to be configured and then a serial interface will be created.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
