Symptom: On N3k platform (N3K-C3548P-10G) with NX-OS 6.0(2)A1(1a), 6.0(2)A1(1b) TCAM misprogramming might be seen for CoPP classes. As a consequence some control plane protocol instabilities might be observed as some of the protocols could be mistakenly going into class-default CoPP class. The routing protocol packets could be intermittently dropped, BGP sessions flapping might be seen due to Holdtimer period expired. Conditions: The issue was seen after NX-OS upgrade to the affected NX-OS versions.
