3925 Etherswitch Service Module Configuration

We have a Cisco 3925 router which had a 4 port DS1 HWIC to run frame relay service through. So we have been running the 3 Gigabit ports to run the rest of the connectivity to the network. However, now the folks are wanting to introduce some web services into the mix which means additional Ethernet ports will have to be put in place, to accomodate a DMZ but we are already using all 3 Ethernet port that come with the 3925.

So we have added a brand new Cisco SM-ES3G-24P Service Module into the router. Although you can figure it through the regular 3925 IOS CLI.

Am correct in assuming that this module acting 100% independantly of the rest of the router as it looks?

There is only one document I have found in configuring service modules (Cisco KDoc ID 82288), and that is the way it looks to me.

Seems kind of a waste to not have some method of transferring the data around internally, and having to string cables between the main router and the Etherswitch module. Just wanted to be sure I am not missing something here.

Yes.  I quote from the Cisco Enhanced EtherSwitch Service Modules Configuration Guide: "The Cisco enhanced EtherSwitch service modules provide Cisco 2900 series routers and Cisco 3900 series routers the ability to use Cisco enhanced EtherSwitch service modules as independent Layer 2 and Layer 3 switches when running Cisco IOS."

I have not downloaded the document, and dont have the Doc ID, so it is probably the same document you're refering to.

The only difference between a stand-alone switch and the Service Module is that the Gigabit Ethernet connection between the router and the services module via the back-plane connectors run, and that they share some system resources.
