seems that the Performance mode is the default mode. Unfortunately you can verify this via command (show chassis hardware) only starting with Junos OS Release 17.3R1. Do you now any way how to confirm in which mode is my vMX? (I did not deploy and install it).
Question B: More, assuming that i do not configure the proper number of vCPU and memory for my VM to support performance-mode (default): can I assume that in case i do not meet the hardware requirement than the vmx is "downgrade" to lite-mode?
Question C: Finally, i want to upgrade the vMX from 15.1F6.9 to the reccomended version 17.3R3-S5. Can i upgrade my vMX as a normal MX router without taking care of the host system (KVM in this case)?
- is the FPC online "show chassis fpc"? This can confirm that your system is running in performance. If its not online, please try to configured the lite-mode and check the status[set chassis fpc 0 lite-mode].
-If you allocate minumum resources to run the vMX it should be running fine in lite-mode. [15.1 is pretty old release, it had lot of limitations] can you please confirm the resoruces cofigured for the vMX in your setup?
- vMX upgraded is not recommended. please plan for a spwaning a vMX and load the config.
- Yes, i see the fpc because we setup the vmx with vcp and vfp. Reading through the line i am assuming the following: I did not configured the lite-mode and the default mode is performance, therefore we can assume that my vmx is in performance mode.
- My question was different: my vmx is now in performance mode (see the above) but is not meeting the hardware resource. I am not sure if this downgrade the vmx into lite-mode (may be i am complicating idea)
- vMX upgraded is not recommended: well the link you sent to me is for vmx-release-notes-18.4r1 which is not my case (upgrade from 15.1F6.9 to 17.3R3-S5)
Finally besides different hardware requirements, any one know what is the difference in terms of scalability between performnace-mode and lite-mode? i could not really find the answer any where.
