How to increase maximum interfaces on NX-OS 9000

[andrewburns]

Hi,

I'm trying to build a simulation that requires more than 20 interfaces on the NX-OS 9000.

It should be a straightforward edit of the YAML file, but the default node definition is read-only.

Hence, I created a new node definition with the 32 interfaces which I need. So far, so good.

However, there are no image definitions available in the new node definition, and when I try to create a new image definition the default ones are not available (at least, I can't find them...)

Has anyone done this before, or know how to find/extract the default NX-OS images?

thanks,

Andrew.

not sure i understood the question correctlu Nexux Virtual support

A maximum of 128 data ports (e1/1, e1/2, ... e1/128) are supported.

My question wasn't about whether it was supported or not - it was about how to configure more than 20 interfaces.

Sure that what i was mentioned we did not understand your question.

If you installed on esxi, you add interface to vSwitch and attached to OVA VM.

Note : i am not sure you looking this in CML ?

try below example :

Hi,

The default node type of NX-OS 9000 in CML only has 20 interfaces.

Try it yourself - add 2 nodes in CML, one of which is a NX-OS 9000 node and if you try to create a link between them you'll see that it only has 20 interfaces defined by default. (Because that's what is in the node definition).

My question is how to increase this limit.

Been Long i have not touched CML2. As per your input  Looks for me that is the Limitation of the product of now (but wait for some one to confirm)

i use OVA or other simulatation and emulation tools using nexus9 virtual  works as expected.

EDIT :

I looked some YML file this possible going to shell make changes, but i have not done this on CML, but other emulators works.

example :

I'm not using "other emulators", I'm using Cisco CML which is why I posted in the Cisco CML discussion forum.

[balaji.bandi]

i can only think of now was -  if you could able to change YML file to extend the interface, or contact TAC to find out the limitation.

[andrewburns]

I'm asking here in case anyone has done this before - and as I'm using the personal edition of CML I don't have TAC support. TAC support only comes with the enterprise edition.

The way I did this was to enter the CML "Tools", "Node and Image Definitions" select the image you want to add more interfaces too and disable "Read-Only". Increase the "Default number of physical interfaces" and select "Update" at the bottom. Then reenabled "Read-Only". Be mindful in these settings because you are editing the default images. This will work for any virtual devices you add in the future moving forward.
