I have been using
- VIRL for a few years
- virtual images on ESxi for 5 years
- GNS on and off for 15 years
- physical hardware for 25 years
my thoughts and feedback of CML
- There doesn't appear to be much support for the product. the community is trying to help each other
- the supplied OVA is not compatible with VMware 6.5. One of my VMware guys fixed it for me
- there is no documentation for CML install on ESXi
- the CML CSR1v image won’t accept tagged frames. This is very basic functionality that should have been tested
- the console ports stop working at times
- i have a 20 node license, but can't have more than 4 IOS-XR, 8 CSR1000v routers and one unmanaged switch without receiving an error that i have exceeded my node count
- i restarted CML via the sysadmin page. I have not regained access since. i have tried restarting the CML virtual machine via vSphere to no success. i reach the console of CML, but am unable to ping the CML address from a device on the same subnet. I have tried running the initial ipconfig python script, but it now fails. This was originally successful. I will likely have to re-install. Not sure what kind of licensing issues that will bring me
- running the solution to use an external terminal editor is odd. i have had to run this tool on all computers that have access to my CML.
- I personally don't think CML is ready for production
- i haven't even tried to build real toplogies yet. this will be the true test
- i will try it again in a few months, when the kinks are ironed out
Would love to hear from Cisco on my experience
on the positive side
It doesn't seem to require nearly as much CPU and RAM as VIRL
It's a pretty design. I like not having to use maestro
