The Network Processor logs discarded packets and keeps a summary of ten categories of “offenders lists”. The top 10 offenders in each category display in IP Policing “offenders list” statistics. For the rogueMediaOffendersList and mediaOffenderListstatistics, a new entry is created when the destination IP address or destination UDP port is different than the existing entries. Some offenders lists include the column “Source Unique.” If the “Source Unique” field is “notUnique”, the packets from multiple source IP addresses or source UDP ports were discarded.  If the source unique field is “unique,” the packets from a single source IP address/UDP port were discarded.

For all other “offenders list” categories, a new entry is created when the source IP address is different than the existing entries.
