Description (partial)


An ACL applied on interface is using object-group. The object-group is changed.
The change could be add new member, delete existing member.

The change was accepted by the system (no error). However, traffic filtering
does not behave correctly. It is as if the accepted change has never occurred.


The ACL has undergone multiple changes. There are multiple edits of object-group
that leads to one single most important trigger of this problem - the edit has
previously failed. In this customer's case, the object-group edit failed because
the resulting ACL requires more TCAM that the system could afford. 

After the error, another object-group edit is accepted, and the problem occurs.

It must be noted that without any prior obj-group edit failure, this issue
cannot occur.
