Ensure the card type ( iom3-xp-b or others) matches the capability of the 12.0.R6 image.
TiMOS (Time-critical Management Operating System), now widely referred to as Nokia SR OS, is a highly resilient, feature-rich network operating system used across service provider networks, global data centers, and enterprise environments. Unlike standard enterprise routing platforms, SR OS is engineered explicitly for intensive Carrier Ethernet, IP/MPLS, and mobile backhaul architectures.
The Timos-sr-12.0.r6-vm.zip file contains the virtual machine image of the Nokia SR OS. This image is designed to run on hypervisors like VMware ESXi, VMware Workstation, or KVM, allowing network engineers to emulate a 7750 Service Router or 7450 ESS node in a virtual environment. 12.0.R6 Platform: Virtual Machine (VM) Timos-sr-12.0.r6-vm.zip Download
Start the node. The console is accessible via Telnet on the port indicated in EVE‑NG. Use the default login credentials: admin Password: admin
The configured Ethernet ports will be named following the pattern slot/MDA/port , such as 1/1/1 to 1/1/5 .
Below is the standard procedure for .
For individual engineers and students working in home labs, obtaining the file can be challenging. The image is often distributed through private collections or community forums. When using such sources, it is critical to verify the file's integrity with checksums if available. You will often find references like:
Requires KVM (VT-x or AMD-V) enabled in your BIOS/Hypervisor. ⚠️ Important Considerations
The TiMOS-SR-12.0.R6-vm.zip file is a powerful tool for networking professionals, providing a risk‑free environment to learn complex routing protocols and carrier‑grade networking. While obtaining the file requires navigating proper channels, once deployed, the virtual 7750 SR offers performance and feature parity with its physical counterpart. mkdir tmp cd tmp unzip
