The c3620 supports up to 2 Network Modules (maximum of 8 Ethernet ports, 32 FastEthernet ports or 8 serial ports).
IOS version 12.4.15T14 (Technology train)įile name: Ģ600s have one or two Ethernet or FastEthernet interfaces on its motherboard, 3 subslots for WICs (maximum of 6 serial ports) and 1 Network Module slot (maximum of 4 Ethernet ports or 16 FastEthernet ports).įile name: įile name: Note that interfaces do not use a slot designation (e.g. It’s specific to each different IOS image.ġ700s have 1 FastEthernet fixed port (C1700-MB-1ETH) on its motherboard, 2 subslots for WICs (maximum of 2 Ethernet ports or 4 serial ports), and no Network Module slots. This settings will help Dynamips to consume less CPU. We really recommend using c3640, c3660, c3725, c3745 and c7200 IOS images listed below, they have proven to be the most stable in GNS3 provided you use the right amount of RAM and Idle-PC value. From experience you can usually use a bit less RAM just fine. The minimum RAM is the amount of memory needed for IOS to work at maximum capacity with most feature configured and activated. We recommend Mainline over Technology train if you are interested on stability without the need of new features.Please see Cisco IOS Versions and Naming for more information. You will find the technology train images to contain the newest features but it may also contain the most bugs. Should I use a mainline and technology train image? Please note that the IOSv appliance is based on IOS 15 and there are IOU (IOS on UNIX) images with IOS 15. All other platforms are now end-of-life and only support IOS 12.4.

Only the c7200 series get newer IOS 15 images. Currently, the c7200 images are the only ones still available for download for those with a support contract. IOS version 12.4.15T14 (Technology train)ĭue to these platforms hitting End of Sale, End of Life, and End of Support status, the images are no longer available for download from Cisco’s support sections.Should I use a mainline and technology train image?.R+Svms are all vendor Routing and Switching images that are larger in size but can be imported into GNS3 for real world network emulation. IOS images are lower in cpu and memory so you can fit more of them in one topology. IOS images are usually run in Dynamips however R+Svms are housed in a virtual machine. What are the differences? Here are the major differences:
These are classified as Routing and Switching virtual machines (or R+Svms) for short. In the new GNS3 1.4, there is a way to run a second category of switches and routers. For older images, we use and maintain Dynamips an emulator dedicated to emulate some Cisco hardware. GNS3 offers multiple ways to emulate IOS.
