Configuring Performance
Parameters
Element Statistics
IP Packet Statistics
To view the IP packet statistics Select Performance > Element Statistics > IP. The following parameters are displayed:
Parameter Description
IP Receives The total number of input datagrams received from interfaces, including those received in error.
IP Header Errors The number of input datagrams discarded due to header error due to errors in their IP headers, including bad checksums, version number mismatch, their format errors, time-to-live exceeded, errors discovered in processing their options, and so on.
IP Discarded The total number of input datagrams discarded. Note: This counter does not include any datagrams discarded while awaiting re-assembly. IP Successfully Delivered The total number of input datagrams successfully delivered to IP user-
protocols (including ICMP).
IP Out Requests The total number of IP datagrams, which local IP user-protocols (including ICMP) supplied to IP in requests for transmission.
IP Out Discards The total number of IP datagrams, which local IP user-protocols (including ICMP) supplied to IP in requests for transmission.
SNMP
To view the SNMP element statistics
Select Performance > Element Statistics > SNMP; the following parameters are displayed:
Parameter Description
SNMP Received Packets The total number of messages delivered to the SNMP entity from the transport service.
SNMP Sent Packets The total number of SNMP messages that were passed from the SNMP protocol entity to the transport service.
SNMP successful 'Get' requests
The total number of MIB objects that have been retrieved
successfully by the SNMP protocol entity as the result of receiving valid SNMP Get-Request and Get-Next PDUs.
SNMP successful 'Set' requests
The total number of MIB objects that have been altered successfully by the SNMP protocol entity as the result of receiving valid SNMP Set-Request PDUs.
SNMP 'get' requests The total number of SNMP Get-Request PDUs processed PDUs that have been accepted and processed by the SNMP protocol entity.
SNMP 'get-next' requests The total number of SNMP Get-Request PDUs that have been accepted and processed by the SNMP protocol entity.
SNMP 'set' requests The total number of SNMP Set-Request PDUs that have been accepted and processed by the SNMP protocol entity.
SNMP Out TooBig The total number of SNMP PDUs that were generated by the SNMP protocol entity and for which the value of the error-status field is tooBig.
SNMP Out NoSuchName The total number of SNMP PDUs that were generated by the SNMP protocol entity and for which the value of the error-status is
noSuchName.
SNMP Out BadValue The total number of SNMP PDUs that were generated by the SNMP protocol entity and for which the value of the error-status field is badValue.
SNMP Out GenErrs The total number of SNMP PDUs that were generated by the SNMP protocol entity and for which the value of the error-status field is genErr.
SNMP Out Get-Responses The total number of SNMP Get-Response PDUs that have been generated by the SNMP protocol entity.
SNMP Out Traps The total number of SNMP Trap PDUs that have been generated by the SNMP protocol entity.
IP Router
To view the IP router element statistics
Select Performance > Element Statistics > IP Router. The following parameters are displayed:
DDoS Protector Web Based Management User Guide | 167
Parameter Description
IP Forwarded The number of input datagrams for which this entity was not their final IP destination, as a result of which an attempt was made to find a route to forward them to that final destination. In entities, which do not act as IP Gateways, this counter will include only those packets that were Source - Routed via this entity, and the Source - Route option processing was
successful.
IP Unknown Protocol The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol.
IP Out No Routes 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 ipForwDatagrams that meet this no-route criterion. Note that this includes any
datagrams, which a host cannot route because all of its default gateways are down. Note: This counter includes any packets counted in ipForwDatagrams, which meet this `no-route' criterion. It also includes any datagrams that a host cannot route because all of its default gateways are down. IP Fragments Received The number of IP fragments received which needed to be
reassembled at this entity. IP Fragments successfully
reassembled
The number of IP datagrams successfully re-assembled.
IP Fragments failed reassembly The number of failures detected by the IP re-assembly algorithm (for whatever reason: timed out, errors, etc). Note: This is not necessarily a count of discarded IP fragments since some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received.
IP datagrams successfully fragmented
The number of IP datagrams that have been successfully fragmented at this entity.
IP datagrams discarded - failed fragmentation
The number of IP datagrams that have been discarded because they needed to be fragmented at this entity but could not be, e.g., because their Do not Fragment flag was set. IP datagram fragments generated The number of IP datagram fragments that have been
generated as a result of fragmentation at this entity. Valid routing entries discarded N/A
IP Fragments successfully reassembled
The number of IP datagrams successfully re-assembled.
