Description (partial)

On and SSC-5 IPS platform, when setting Anomaly Detection (not supported on SSC-5) and adding a physical interface in the virtual sensor, the IPS produces a LogicException failure.  See example:

sensor(config)# ser analysis
sensor(config-ana)# vir vs0
sensor(config-ana-vir)# anomaly-detection 
sensor(config-ana-vir-ano)# operational-mode inactive
sensor(config-ana-vir-ano)# ex
sensor(config-ana-vir)# physical-interface  gigabitEthernet0/0 
sensor(config-ana-vir)# ex
sensor(config-ana)# ex
Apply Changes?[yes]: 
Error: editConfigDeltaAnalysisEngine :  Cid::LogicException caught - Unable to complete the requested transaction.

It appears from early testing that when making the AD and physical-interface changes twice consecutively, this failures will occur.

Once this failure occurs, interface changes will continue to fail.  The SSC-5 sensor must be reset to recover.
