Description (partial)

After moving static bindings from EPG A to EPG B, static bindings are not deployed on the leaf switch. This is because the EPG is in lazy mode, which means the policy element needs the dynamic policy notification from EPM to download the policies. This condition is treated by the policy element as an add and delete of the EPG. This condition is treated as just an update from the EPM point of view.

This issue occurs if the following conditions are met:

1) Static bindings have deployment immediacy set to on-demand.
2) Static bindings are deleted and added in the same POST.
