Usecase

You have multiple objects identified that you want to delete, for example a bunch of EPGs, some static bindings, etc. For these objects you got a DN, maybe through a moquery command.

In our example we want to delete all the EPGs in the “Network” Tenant, that have an “X” in them.

With an easy moquery command we can find the DNs of our objects.

APIC1# moquery -c fvAEPg | grep "dn" | grep "X"
dn                   : uni/tn-Network/ap-AP/epg-7-X
dn                   : uni/tn-Network/ap-AP/epg-8-X

Delete multiple objects by DN

Alright, we got our DNs, through whatever means :) Now we add them to a file, which we then use to delete them. You can name the file howere you want, I go for a simple dn.txt here. Then but the DNs in it.

APIC1# cat dn.txt
uni/tn-Network/ap-AP/epg-7-X
uni/tn-Network/ap-AP/epg-8-X

Now we are ready to launch the magic and delete the DNs from the APIC.

Please be careful! Make sure that you understand what this script does before you launch it! I can’t and won’t take any responsibility for this script and the output of it

We cat the file and then loop over each line and assume it’s a DN. With the help of icurl we delete it then from the fabric.

cat dn.txt | while read f; do icurl -g -k -X DELETE https://localhost/api/mo/"${f}".json; done;

That’s it, the DNs are gone for good! This can be really helpful if you got a lot of DNs to delete 👍

Brackets in the DN

If you have brackets in the DN, make sure to use the icurl -g option. Otherwise you will face an error like

1

curl: (3) bad range in URL position 78:

E.g. of the DN:
