CISCO-NAT-CGN-EXT-MIB

This MIB module extends the IETF draft NAT MIB available at
        http://tools.ietf.org/html/draft-ietf-behave-nat-mib-11 
        The extensions are intended to address the needs of the Carrier
        Grade NAT (CGN), also known as Large Scale NAT (LSN).
        
        GLOSSARY
        ==========
        Address mapping - is used to refer to association between
        a private IP to public IP (in case of NAT44 and DS Lite)
        or source IPv6 address to IPv4 address in case of NAT64 
        stateful application.
        
        Mapping - A mapping used to refer to a NAT translation record.
        It is a record held in memory that maps a private IP address
        and port to a public IP address and port.
        
        Subscriber - A subscriber is a record held in memory that
        provides IP address and other details of an end user device
        which has one or more mappings.
        
        Session - A session is a record maintained in memory that
        identifies a flow. The flow is uniquely identified by the
        source IPv4/IPv6 address, source port, translated IP address,
        translated source port, destination IPv4/IPv6 address and
        destination port.
        
        In to Out packet - A packet originating from a subscriber,
        with a private source address (or with an IPv6 address in
        case of NAT64), destined to a host with a public IP address.
        This packet needs NAT (or NAPT) service.
        
        Out to In packet - A packet originating from a host on the
        public Internet (or any host with a routable/public) source
        address, whose destination address is a mapped (translated)
        IP address. This packet needs reverse-NAT.
        
        Bulk port allocation - A NAT instance can be configured
        pre-allocate a range of contiguous ports instead of a single
        port. A mapping log record is created indicating the range of
        ports allocated to this subscriber. This is done in anticipation
        that the subscriber is likely to send packets that require more
        mappings to be created. For the subsequent mapping requests, one
        of the pre-allocated port is used and no additional log entries
        need to be created. This is a technique used to reduce the
        volume of translation record data.
