please change the doc to below. rest all looks good to me.
RCA:
After upgrading the leaf to an affected version, interface configurations are not pushed because the "pres.Listener" object is missing in the APIC.
This occurs due to an incomplete/faulty APIC upgrade.

IMPACT:
If "pres.Listener" is missing after a leaf upgrade or clean reload, leaf ports remain out of service, and infraAccPortP and infraAccBndlGrp cannot program interfaces.

Suggestion:
Verify that all active leaf node objects are present in the "pres.Listener" list (class 4307) and alert if the affected version is detected. If an alert is raised, upgrade to a version that includes the fix for [CSCwn81692][62].
