Description
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.

| cNatCgnCounterOutOfSessionDrops OBJECT-TYPE This object indicates the number of packets dropped because they required a new session entry to be created, however, there is no space to create new sessions. | 1.3.6.1.4.1.9.9.818.1.2.1.1.3 | Counter64 | read-only | current |
| cNatCgnCounterSessionLimitDrops OBJECT-TYPE This object indicates the number of packets in either in to out or out to in direction dropped because of exceeding limit on session entries. | 1.3.6.1.4.1.9.9.818.1.2.1.1.4 | Counter64 | read-only | current |

For NAT44 configured in predefined mode, NAT64 stateful or DS Lite, it could be drops due to source IP address not matching the configured prefix bits. | 1.3.6.1.4.1.9.9.818.1.2.1.1.6 | Counter64 | read-only | current |
| cNatCgnCounterEndPointFilteringDrops OBJECT-TYPE This object indicates the number of packets in the out to in direction dropped because of end point dependent filtering policy. Note, the value of this object should be interpreted in conjunction with the value of cNatCgnInstanceBehaviorType. If the NAT instance is configured with endpointIndependent behavior, the instance is not supposed to filter or drop any packets based on the destination. In such case this counter could either be zero or could be the number of packets passed which would have otherwise be filtered and dropped if cNatCgnInstanceBehaviorType is set to addressDependent or addressAndPortDependent. | 1.3.6.1.4.1.9.9.818.1.2.1.1.7 | Counter64 | read-only | current |

| cNatCgnCounterFragmentPktsOutToInDrops OBJECT-TYPE This object indicates the number of fragmented packets in the out to in direction dropped due to errors such as timed out waiting for first fragment or no space to hold the fragment. | 1.3.6.1.4.1.9.9.818.1.2.1.1.11 | Counter64 | read-only | current |
| cNatCgnCounterCurrentPortAllocation OBJECT-TYPE This object indicates the current average port allocation across all available public IP addresses applied to this NAT instance. When bulk allocation is enabled (that is, the value of cNatCgnInstanceProtocolPortBulkAllocControl is more than 1), this value will include all the ports pre-allocated in bulk (whether they are in use or not). | 1.3.6.1.4.1.9.9.818.1.2.1.1.12 | Integer32 (0..100) | read-only | current |
| cNatCgnCounterPortUsageLowThreshold OBJECT-TYPE This object specifies the low threshold in percentage of available public ports that are used up. The notification cNatCgnNotifPortUsageWatermarkLow is sent once the value of cNatCgnCounterAveragePortAllocation becomes less than or equal to this value.

| cNatCgnCounterPortUsageClearLowThreshold OBJECT-TYPE This object specifies the clear low threshold in percentage of available public ports that are used up. The notification cNatCgnNotifPortUsageWatermarkLowClear is sent once the value of cNatCgnCounterAveragePortAllocation becomes more than or equal to this value. If this object is set to zero, the notification is not generated. Implementations must ensure that values of objects cNatCgnCounterPortUsageClearLowThreshold and cNatCgnCounterPortUsageLowThreshold remain consistent. For example, an implementation must respond with an inconsistentValue error if an attempt is made to set the the value of cNatCgnCounterPortUsageClearLowThreshold to be less than or equal to that of cNatCgnCounterPortUsageLowThreshold and vice versa. | 1.3.6.1.4.1.9.9.818.1.2.1.1.14 | Integer32 (0..100) | read-write | current |
| cNatCgnCounterPortUsageHighThreshold OBJECT-TYPE This object specifies the high threshold in percentage of available public ports that are used up. The notification cNatCgnNotifPortUsageWatermarkHigh is sent once the value of cNatCgnCounterAveragePortAllocation becomes higher than or equal to this value. If this field is set to zero, the notification is not generated. | 1.3.6.1.4.1.9.9.818.1.2.1.1.15 | Integer32 (0..100) | read-write | current |
| cNatCgnCounterPortUsageClearHighThreshold OBJECT-TYPE This object specifies the clear high threshold in percentage of available public ports that are used up. The notification cNatCgnNotifPortUsageWatermarkHighClear is sent once the value of cNatCgnCounterAveragePortAllocation becomes less than or equal to this value. If this object is set to zero, the notification is not generated. Implementations must ensure that values of objects cNatCgnCounterPortUsageClearHighThreshold and cNatCgnCounterPortUsageHighThreshold remain consistent. For example, an implementation must respond with an inconsistentValue error if an attempt is made to set the the value of cNatCgnCounterPortUsageClearHighThreshold to be more than or equal to that of cNatCgnCounterPortUsageHighThreshold and vice versa. | 1.3.6.1.4.1.9.9.818.1.2.1.1.16 | Integer32 (0..100) | read-write | current |
| cNatCgnCounterAverageBulkPortUsage OBJECT-TYPE This object indicates the average percentage usage of ports pre-allocated in bulk. This value is valid only if the bulk allocation is configured. That is the value specified by the cNatCgnInstanceProtocolPortBulkAllocControl is more than 1. This value gives hints about effectiveness of bulk port allocation technique. A very low percentage of bulk port usage may suggest that, bulk allocation size be reduced. On the other hand, a value close to 100 may hint at increasing the bulk size to further reduce log data volume. | 1.3.6.1.4.1.9.9.818.1.2.1.1.17 | Gauge32 (0..100) | read-only | current |

| cNatCgnLogStatMappingDeleteRecords OBJECT-TYPE This object indicates the number of translation delete records generated. It could be Netflow or Syslog records. It may not always necessarily be equal to number of mappings deleted (natMappingRemovals of the NAT-MIB). If bulk allocation is enabled, this number could be much smaller than natMappingRemovals. If the NAT mode is configured to be pre-defined or if logging is not configured, this could be zero. | 1.3.6.1.4.1.9.9.818.1.2.2.1.2 | Counter64 | read-only | current |
| cNatCgnLogStatSessionCreateRecords OBJECT-TYPE This object indicates the number of session create records generated. It could be Netflow or Syslog records.

The rest of the objects of this entry are valid only if the cNatCgnALGStatus is set to enabled. | 1.3.6.1.4.1.9.9.818.1.2.3.1.2 | INTEGER {notApplicable(1), unSupported(2), notEnabled(3), enabled(4)} | read-only | current |
