Does CML(Cisco Modeling Labs) support a duplicate connection?

[connorkyg]

Hi Experts!

I'm planning to get CML Personal version and I've been trying it with a trial version from the DevNet Sandbox.

It seems that CML support most of command as actual Cisco devices.

1. How do you connect to CML Personal? (not trial)

- Trial version send you a VPN information to access CML, so that you only can have one person to use it.

2. Does CML support commands as Cisco devices?

btw, I'm sorry if my questions are not so clear.

Thank you.

 the DevNet Sandbox is not a trial version of CML. it is full working CML and example of what you get when you purchase one of 2 editions of CML: Personal and Personal Plus.  Once you purchase CML, you must install it on your own PC or server box. The better, the more powerful your PC is, the stronger and better CML will run allowing you to run more devices and complex labs.  Note that min. requirements of 4-core CPU (preferable Intel), 8 Gig RAM, will let your run very small lab.  You can access your CML directly via browser or via home network from another PC.  see # 7 What resources are required by each node in FaQs link below.

CML includes virtual images that could be categorized into generic image of a router and switch (IOSv) and specific replicas like Nexus and XR or CSR 1000v which can be purchase and install in production.  Note those images are "adopted" to work in a virtual environment whcih does not have layer 1.  So, some features are not supported and/or not really working despite the fact that commands are available.  However, IOS commands and features you need for CCNP lever exam are there (not sure about CCIE level).  

Once you purchase CML, you will get a single PC license code that must be authenticated with Cisco via Internet.  you can move your CML to another PC and re-authenticated again but it is a single-usage license.  I don't think you can have multi-user connections to the same CML install. 

CML official support is at CLN sub-forum,

CML FaQ and installation is at https://developer.cisco.com/docs/modeling-labs/#!faq/reference-platform-and-images-questions

So what I understood is that,

I can access to the CML from another PC and edit it as well.

But it allows only 1 connection at the same time.

Thank you so much for your answer!

It helped a lot.

Have a nice day

Yes, main access is via browser like Chrome and Firefox (not sure about others).  You can access CML directly (linux CLI on PC where CML is installed), but that's usually for troubleshooting. 

I have not tried multi-user connections; neither have heard or read anyone else did.  it is possible but unlikely.

Main thing is single-usage license; if you need to move CML to different PC, you can but you must follow instructions; otherwise CML will not work and you will need to contact CML people.
