Severity: 2-Critical

Symptoms

Missing port-motion events between interfaces on r15k/r10k platform can result in missing L2 entries.

Impact

Missing port-motion causes missing L2 entries, resulting in excessive DLFs.

Conditions

Port-motion between the following sets of ports on the r5k appliance: 1.0 - 2.0 3.0 - 7.0 4.0 - 8.0 5.0 - 9.0 6.0 - 10.0 In addition, the following ports on the r10k are affected: 11.0 - 12.0 13.0 - 17.0 14.0 - 18.0 15.0 - 19.0 16.0 - 20.0
