This MIB is used to acquire ip accounting information.
        
        The h3cIpaAccountListTable is set by user to define the group of ip address
        which they want to account.
        This module can be enabled in each port,
        which was defined in the h3cIpaIfConfigTable.
        
        If this module has been enabled, the packets will be accounted
        when crossing the router from the ports having been enabled by user,
        according to whether the source/destination ip address is in h3cIpaAccountListTable
        and what kinds of function(in/out/both/fw) are enabled
        and also whether it is denied by the firewall.
        If it is denied by the firewall, it will be accounted in h3cIpaFWListTable
        If it is accepted by the firewall, and ip source or ip destination is in h3cIpaAccountListTable,
        it will be accounted in h3cIpaIntListTable, otherwise it will be accounted
        in h3cIpaExtListTable.
        
        And IP Accounting function also differentiates the packets by direction.
        If the packet is inbound, the accounting information can be seen as
          h3cIpaIntListInPackets/h3cIpaIntListInBytes in h3cIpaIntListTable,
          h3cIpaExtListInPackets/h3cIpaExtListInBytes in h3cIpaExtListTable,
          h3cIpaFWListInPackets/h3cIpaFWListInBytes in h3cIpaFWListTable.
        
        or else the accounting information can be seen as
          h3cIpaIntListOutPackets/h3cIpaIntListOutBytes in h3cIpaIntListTable,
          h3cIpaExtListOutPackets/h3cIpaExtListOutBytes in h3cIpaExtListTable,
          h3cIpaFWListOutPackets/h3cIpaFWListOutBytes in h3cIpaFWListTable.
