When studying for NSR1, NSR2 or SRA choosing the right network simulator can be a tough decision. And there’s no best way to go about making your selection. After all, you’ve got an exam coming up. Our opinion and advice is to use eve-ng for all Nokia labs because of its simplicity and powerful. This article How to emulate Nokia Service RouterSROS will discuss about this.

What is EVE-NG?

EVE-NG (Emulated Virtual Environment Next Generation) is a multi-vendor virtual network simulator that, similar to VIRL Personal Edition, was developed for individuals and smaller businesses. They offer a free Community Edition as well as a Professional Edition for $110.75 per year.

You can download Eve-ng Free Community Editon on this link: https://www.eve-ng.net/index.php/download/. Choose OVF version for the next-step.

What is VMware Workstation

VMware Workstation is a line of Desktop Hypervisor products which lets users run virtual machines. For our lab, we use VMware to build Eve-ng for simulation. We recommend to download and use VMware Workstation Pro version. There are many user guide and how to download, setup VMware in the internet so we don’t focus in here.

How to emuxlate Nokia Service Router (TiMOS SROS) with Eve-ng

Setup Eve-ng

You can refer to how to install eve-ng on vmware on the official page of eve-ng.

Download SROS timos-13.0.R4 or timos-15.0.R3. Link update in the comment page.

Let’s start setup:

Step 1: Start up the Eve in the VMWare and get ip to FTP:

Step 2: Use FileZilla upload the SROS to the EVE, default username/password is root/eve

Upload timos-13.0R4 folder (include hda.qcow2 inside) to /opt/unetlab/addons/qemu

Setup Node

Step 1: Login to the eve by browser and create a new lab

You can login to the guide with username/password default is admin/eve. For this exam is http://10.1.1.130

Choose icon Add new lab, write down the Name and Save.

Step 2: Create nodes and optimize

Add an object -> Node and choose some option bellow:

  • Template: Nokia 7750 VSR
  • Number of nodes to add: For example is 2
  • Name/prefix: you can write R. After finish it will appear R1 and R2 for this example.
  • Icon: What eve you want, but Nokia should use SROS.png

After all, you scroll down and click Save

Right click to each node choose Edit and change QEMU custom options as follows and Save:

R13:

-nographic -enable-kvm -uuid 00000000-0000-0000-0000-000000000000 -rtc base=2015-03-10

R15:

-nographic -enable-kvm -uuid 15b03403-d9a5-463b-9816-0884b004a972 -rtc base=2017-07-20

Change Timos Line

slot=A chassis=SR-c12 slot=1 card=iom-xp mcm/1=mcm-xp mda/1=m10-1gb-xp-sfp

R21:

Change Qemu option:

-smbios type=1 -machine type=pc-1.0,accel=kvm -serial mon:stdio -nographic -no-user-config -nodefaults -rtc base=2021-05-01 -cpu host -uuid 00000000-0000-0000-0000-210000000070

Change Timos Line:

chassis=SR-1 slot=A card=iom-1 mda/1=me6-100gb-qsfp28

In this example, you can connect 2 routers together with Port 1/1/1 in router R1 and Port 1/1/1 in router R2

Turn it on, telnet by SecureCRT or PuTTY and login with user/pass is admin/admin.

      Add the following to the Qemu options:
      -cpu qemu64,+x2apic

      Like this
      -smbios type=1 -machine type=pc-1.0,accel=kvm -cpu qemu64,+x2apic -serial mon:stdio -nographic -no-user-config -nodefaults -rtc base=2021-05-01 -cpu host -uuid 00000000-0000-0000-0000-210000000070

      Reading around different forums R20 and after for Timos seems to be really picky for hardware, also it’s a big resource hog now it instantly eats 2.4G of memory for R21. Old R12 uses 500MB on boot, if it weren’t for lack of supported protocols I wouldn’t use R21 even with EVENG UKSM I think. Ty very much to adminreboot for lic, though. Incredibly helpful to not reboot mid lab.

    I am having issues with R15

    Attempting to exec primary configuration file:
    ‘cf3:\config.cfg’ …
    MINOR: CLI Unknown card type “iom-xp”.

    MAJOR: CLI #1009 An error occurred while processing a CLI command –
    File cf3:\config.cfg, Line 1: Command “/configure card 1 card-type “iom-xp”” failed.

    CRITICAL: CLI #1002 The system configuration is missing or incomplete because an error occurred while processing the configuration file.

    Because of this there is no lic and the node boots with nothing configured. Normally this would not be an issue but if there is a fix to

    I’d like to use different card type and mda type such that I can have port operating on 1Gbps instead of anything higher, reason being is that I can only emulate cisco devices using 1Gbps interfaces (enterprise grade routers). For the Timos Line mentioned in the blog only supports the following mda types:

    “me16-25gb-sfp28+2-100gb-qsfp28”
    “me6-100gb-qsfp28”
    “me3-200gb-cfp2-dco”
    “me12-100gb-qsfp28”
    “me3-400gb-qsfpdd”
    “me6-400gb-qsfpdd”
    And none of them are 1Gbps.

    Anyone knows the correct options?
