Hi all,

I found this script and I have the issue to understand where I can change myvlanrange.

Any ideas?

Thanks.

what about the json file? you can change the vlan value within the json file.

You can send the json file to me, I will fix your problem.

Hi Juraj,

It is at 'EncapBlk(vlanPhysDomPMo, "vlan-3000", "vlan-3000", name="PhysVlanPoolCCIE")', where you can give your vlan range, the second and third parameters are nothing but 'start-vlan' and 'end-vlan'
