Back to your question: The FRSW(frame relay switch) by default is only a frame switch. You don't have to configure it to be a frame switch because that's all it does. The problem with using dynamips, from what I know, is that PVC's are always active(as opposed to inactive or deleted). But in the grand scheme of things it's really unimportant. Don't worry too much about the frame switch except knowing what the purpose is and how to configure it. Port:dlci = port:dlci

Are they interfaces on a router? I know about WIC's but I have never seen this one beforeslot0 = NM-4E slot1 = NM-4T Modular routers were covered when I took the Cisco CCNA Network Academy courses.... a 2600 router has 2 WIC slots and an NM slot. You can install different available modules to get various network interface options. 3600 routers have NM Slots (and NMs can come with WIC or VIC slots). The 3620s have 2 NM slots. The 3640s have 4 NM slots. 7200 routers have the PAs..... You can read the "all_config_options.txt" file in the Dynagen sample labs directory to get an idea what modules are available to "install" in your emulated routers (and also find out what routers can be emulated).
