Use IP Statistics attributes to monitor traffic and fragmentation statistics for data using the IP (Internet Protocol) protocol. IP Statistics is a single-instance attribute group.
Datagrams/sec The rate that IP datagrams are received from or sent to the interfaces, including those in error. Any forwarded datagrams are not included. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 5,737 for the rate that IP datagrams are received or sent to the interfaces, enter 5737.
Datagrams Forwarded/sec The rate of input datagrams for this entity was not their final IP destination. An attempt was made to find a route to forward the datagrams to their final destination. In entities that do not act as IP gateways, this rate includes only those packets that were Source-Routed via this entity, and the Source-Route option processing was successful. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 55,203 for the rate that datagrams are forwarded per second, enter 55203.
Datagrams Outbound Discarded The number of output IP datagrams for which no problems were encountered to prevent their transmission to their destination, but which were discarded (for example, for lack of buffer space). This counter includes datagrams counted in Datagrams_Forwarded, if any such packets met this (discretionary) discard criterion. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 351 for the number of output IP datagrams that are discarded, enter 351.
Datagrams Outbound No Route The number of IP datagrams discarded because no route could be found to transmit them to their destination. This counter includes any packets counted in Datagrams_Forwarded that meet this 'no route' criterion. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 2,467 for the number of IP datagrams that are discarded, enter 2467.
Datagrams Received Address Errors The number of input datagrams discarded because the IP address in their IP header destination field was not a valid address to be received at this entity. This count includes addresses that are not valid (for example, 0.0 0.0) and addresses for classes that are not supported (such as Class E). For entities that are not IP gateways and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 52 for the number of IP datagrams that are discarded because of address errors, enter 52.
Datagrams Received Delivered/sec The rate that input datagrams are successfully delivered to IP user-protocols (including ICMP). Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 467 for the number of IP datagrams that are successfully delivered, enter 467.
Datagrams Received Discarded The number of input IP datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (for example, for lack of buffer space). This counter does not include any datagrams discarded while awaiting re-assembly. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 235 for the number of IP datagrams that are received and discarded, enter 235.
Datagrams Received Header Errors The number of input datagrams discarded due to errors in their IP headers, such as bad checksums, version mismatch, other format errors, time-to-live exceeded, and errors discovered in processing their IP options. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 754 for the number of IP datagrams that are discarded due to header errors, enter 754.
Datagrams Received/sec The rate that IP datagrams are received from the interfaces, including those in error. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 3,561 for the rate that IP datagrams are received, enter 3561.
Datagrams Received Unknown Protocol The number of locally-addressed datagrams received successfully, but discarded because of an unknown or unsupported protocol. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 375 for the number of IP datagrams that are discarded because of an unknown or unsupported protocol, enter 375.
Datagrams Sent/sec The rate that IP datagrams are supplied to IP for transmission by the local IP user-protocols (including ICMP). This counter does not include any datagrams counted in Datagrams_Forwarded. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 1,358 for the rate that IP datagrams are sent per second, enter 1358.
Fragment Re-assembly Failures The number of failures detected by the IP re-assembly algorithm (such as time out, errors, and so on). This is not necessarily a count of discarded IP fragments since some algorithms (notably RFC 815) can lose track of the number of fragments by combining them as they are received. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 349 for the number of failures detected by the IP re-assembly algorithm, enter 349.
Fragmentation Failures The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be because their 'Don't Fragment' flag was set. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 90 for the number of IP datagrams that are discarded because their 'Don't Fragment' flag is set, enter 90.
Fragmented Datagrams/sec The rate that datagrams are successfully fragmented at this entity. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 2,467 for the rate that IP datagrams are successfully fragmented, enter 2467.
Fragments Created/sec The rate that datagrams are successfully fragmented at this entity. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 327 for the rate that IP datagrams are created per second, enter 327.
Fragments Re-assembled/sec The rate that IP fragments are successfully re-assembled. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 350 for the number of IP fragments are successfully re-assembled per second, enter 350.
Fragments Received/sec The rate that IP fragments that need to be re-assembled at this entity are received. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 5,329 for the rate that IP fragments are received per second, enter 5329.
