vrNsDropConditions
Virtual Router Ns Dropped Conditions
This attribute controls under what circumstances NetSentry drops packets. It is possible for NetSentry to drop packets when: There is no memory to contain statistics for this packet (statsNoMem), it is for whatever reason impossible to clone, copy, or log a copy of the packet via the clone_to copy_to or log_to actions respectively (cantCloneTo, cantCopyTo and cantLogTo), and if the packet encounters a filter which is provisioned at a filter point within a protocol component, but not defined in any of the files defined by File components within NetSentry (this is a Null filter). Description of bits: statsNoMem(0) cantCloneTo(1) cantLogTo(2) cantCopyTo(3) cantMacCloneTo(4) nullFilter(5)
