ACI Learning Labs problem

Hi all,

I'm stuck with a problem on ACI Programmability Options lab, section APIC Sandbox Environment Setup, it says:

# From within the correct virtual environment (venv) apic_fabric_setup\ $ python baseline.py

# Expected Output

Baselining APIC Simulator for Learning Labs

Setting up Fabric Nodes

Configuring Fabric Policies

Setting up Common Tenant

Setting up Heroes Tenant

Setting up SnV Tenant

But my output is:

(venv) C:\Python27\aci-learning-labs-code-samples\apic_fabric_setup>baseline.py

Baselining APIC Simulator for Learning Labs

Setting up Fabric Nodes

Configuring Fabric Policies

Any ideas what I may have done wrong?

Thanks,

You are NOT doing anything wrong.

Overlapping interfaces - server has something already configured

Hello all, so what is the fix here? I am running into a similar issue within the 1st page of the

Intermediate ACI Programmability module

I run the baseline.py script and I get the following , looks like it is not able to import anything in the cobra library:

(venv) C:\Python27\CISCO_DEVNET\aci-learning-labs-code-samples\apic_fabric_setup>python baseline.py

I had same issue with interface profiles- validation failed overlapping interfaces error

the solution was that I was missing the to and from port in the range.

"children": [{
"infraPortBlk": {
"attributes": {
"dn": "uni/infra/accportprof-LEAF{{node}}/hports-E{{port}}-typ-range/portblk-block2",
"fromPort": "{{port}}",
"toPort": "{{port}}",

I added those two values and it now works.

the APIC API blows. I'm running 4 code and i'm getting the same error from my APIC. I go and delete the interface from the access port selector list and then try to readd it thru API and can't.

Their validation is not in sync with is showing up in the APIC GUI. It seems like once you create a policy in the GUI, you can't recreate it in the API if it's ever been created. There must be something somewhere else holding onto the values in the port profile/interface selecctors.

Did you ever get a solution to this issue?

Could you resolve the issue?

Hi,

Get into the sandbox and delete what ever policy is giving a duplicate, it is just giving you and error because someone else already ran the script on the same sandbox which is causing the duplicate/overlap.

I did this and it worked fine.
