CSR 1000v IOS XE Release 3.10.0S or later - Download PageĬisco CSR 1000v Installation on Qemu Virtual Machine.Qemu 1.6.0 or later and compiled for i386 or x86_64 support (Qemu 0.12 is officially supported).Linux Fedora 17 x86-64 (or any other x86 or x86-64 Linux) with working KVM and Qemu installation.Processor with built-in hardware virtualization support (VT-x or AMD-V).Each CSR 1000v Virtual machine consumes 4 GB RAM plus 2 GB RAM for OS and installed applications e.g.As the both Guest and Host CPU are the same x86 architecture, Qemu can use kvm for hardware assisted virtualization. In a last part of the tutorial we will configure GNS3 to support CSR 1000v Qemu Virtual machine and test connection between CSR 1000v and Cisco 3725 both running inside GNS3.

The goal of this tutorial is to install CSR 1000v IOS XE 3.10 on a virtual machine that is run by Qemu hypervisor. Thanks to the this awesome enhancement, Cisco CSR 1000v running IOS XE 3.10 can be easily connected to devices running inside GNS3 topology. I hope that this has been helpful for you.The Cisco IOS XE Release 3.10 brings support for Kernel Based Virtual Machine ( KVM) hypervisor. Here is what the flash looks like post upgrade.

Below we have successfully loaded 03.06.06E onto the switch.Īs a post clean up task you should execute the command software clean switch 1. Once the switch has successfully finished reloading, you can log back in and confirm that the new version was successfully applied. It will take several minutes to reload, during the reload processes the switch does several post-installation tasks such as updating the Front-end Microcode. The switch prepares the image for installation below you see the switch performing pre-installation tasks. Switch# software install file usbflash0:cat3k_caa-universalk9.SPA.03.06.06.E.152-2.E6.bin I have chosen to use a USB drive to place my source image on, but you can still use a transfer protocol like TFTP or SCP.Īfter confirming that you have your source image in its proper location, execute the following command on the switch with your source image accurately defined. The new software version here will be 03.06.06E. You can see from the output of the 3650 that the current software version is 03.06.05b.e and it is running in Install Mode.ĭownload your image from Cisco. I would suggest operating in Install mode as this is the default, and provides you with a modular system, you can switch them if you choose. It consumes more memory than Install mode because packages are extracted from the bundle and copied to RAM. Cisco recommends not altering any of the files.īundle mode uses monolithic Cisco IOS images to boot the switch. pkg files found in the flash drive that provide a specific function to the OS. Install mode uses a package-provisioning file named nf, which is in charge of booting the switch. The Cisco Catalyst 3650, 3850, and 9K series switches have two modes of operation, Install Mode and Bundle Mode. Now that you have some understanding of the differences between IOS and IOS-XE you need to understand that there is two modes of operation. Individual sub packages create IOS-XE that can be upgraded individually.Multiprocessing allows for workloads to be shared across multiple CPUs.A single process could crash the entire system.Monolithic – The OS and its processes run in the same address space on the same hardware.

You can also review upgrade procedure for specific hardware.Īs a quick introduction, here are some differences between IOS and IOS-XE.

So today we will be going through the software upgrade process for a 3650 running in install mode. IOS-XE isn’t new, I prefer it over IOS because of its Linux base and the processing advantages it has. I got my hands on a Cisco Catalyst 3650-48PD-L switch which is the first access level switch that I’ve dealt with that is running IOS-XE.
