The Traceroute MIB (DISMAN-TRACEROUTE-MIB) provides access to the traceroute capability at a remote host. read-write current 1.3.6.1.2.1.81.1.1 "requests" The maximum number of concurrent active traceroute requests that are allowed within an agent implementation. A value of 0 for this object implies that there is no limit for the number of concurrent active requests in effect. read-write current 1.3.6.1.2.1.81.1.1 "requests" The maximum number of concurrent active traceroute requests that are allowed within an agent implementation. A value of 0 for this object implies that there is no limit for the number of concurrent active requests in effect. not-accessible current 1.3.6.1.2.1.81.1.2.1 Defines an entry in the traceRouteCtlTable. The first index element, traceRouteCtlOwnerIndex, is of type SnmpAdminString, a textual convention that allows for use of the SNMPv3 View-Based Access Control Model (RFC 2575 [11], VACM) and allows an management application to identify its entries. The second index, traceRouteCtlTestName (also an SnmpAdminString), enables the same management application to have multiple requests outstanding. not-accessible current 1.3.6.1.2.1.81.1.3.1 Defines an entry in the traceRouteResultsTable. The traceRouteResultsTable has the same indexing as the traceRouteCtlTable in order for a traceRouteResultsEntry to correspond to the traceRouteCtlEntry that caused it to be created. not-accessible current 1.3.6.1.2.1.81.1.4.1 Defines a table for storing the results of a traceroute operation. Entries in this table are limited by the value of the corresponding traceRouteCtlMaxRows object. The first two index elements identify the traceRouteCtlEntry that a traceRouteProbeHistoryEntry belongs to. The third index element selects a single traceroute operation result. The fourth and fifth indexes select the hop and the probe for a particular traceroute operation. not-accessible current 1.3.6.1.2.1.81.1.5.1 Defines an entry in the traceRouteHopsTable. The first two index elements identify the traceRouteCtlEntry that a traceRouteHopsEntry belongs to. The third index element, traceRouteHopsHopIndex, selects a hop in a traceroute path. read-write current 1.3.6.1.2.1.81.1.2.1.3 Specifies the type of host address to be used on the traceroute request at the remote host. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-write current 1.3.6.1.2.1.81.1.2.1.4 Specifies the host address used on the traceroute request at the remote host. The host address type can be determined by the examining the value of the corresponding traceRouteCtlTargetAddressType index element. A value for this object MUST be set prior to transitioning its corresponding traceRouteCtlEntry to active(1) via traceRouteCtlRowStatus. read-write current 1.3.6.1.2.1.81.1.2.1.5 The purpose of this object is to optionally enable bypassing the route table. If enabled, the remote host will bypass the normal routing tables and send directly to a host on an attached network. If the host is not on a directly-attached network, an error is returned. This option can be used to perform the traceroute operation to a local host through an interface that has no route defined (e.g., after the interface was dropped by routed). 1 2 read-write current 1.3.6.1.2.1.81.1.2.1.6 "octets" Specifies the size of the data portion of a traceroute request in octets. A traceroute request is essentially transmitted by encoding a UDP datagram into a IP packet. So subtracting the size of a UDP header (8 octets) and the size of a IP header (20 octets) yields a maximum of 65507 octets. read-write current 1.3.6.1.2.1.81.1.2.1.7 "seconds" Specifies the time-out value, in seconds, for a traceroute request. read-write current 1.3.6.1.2.1.81.1.2.1.8 "probes" Specifies the number of times to reissue a traceroute request with the same time-to-live (TTL) value. read-write current 1.3.6.1.2.1.81.1.2.1.9 "UDP Port" Specifies the UDP port to send the traceroute request to. Need to specify a port that is not in use at the destination (target) host. The default value for this object is the IANA assigned port, 33434, for the traceroute function. read-write current 1.3.6.1.2.1.81.1.2.1.10 "time-to-live value" Specifies the maximum time-to-live value. read-write current 1.3.6.1.2.1.81.1.2.1.11 Specifies the value to store in the Differentiated Services (DS) Field in the IP packet used to encapsulate the traceroute probe. The DS Field is defined as the Type of Service (TOS) octet in a IPv4 header or as the Traffic Class octet in a IPv6 header. The value of this object must be a decimal integer in the range from 0 to 255. This option can be used to determine what effect an explicit DS Field setting has on a traceroute response. Not all values are legal or meaningful. DS Field usage is often not supported by IP implementations. A value of 0 means that the function represented by this option is not supported. Useful TOS octet values are probably '16' (low delay) and '8' ( high throughput). read-write current 1.3.6.1.2.1.81.1.2.1.12 Specifies the type of the source address, traceRouteCtlSourceAddress, to be used at a remote host when performing a traceroute operation. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-write current 1.3.6.1.2.1.81.1.2.1.13 Use the specified IP address (which must be given as an IP number, not a hostname) as the source address in outgoing probe packets. On hosts with more than one IP address, this option can be used to force the source address to be something other than the primary IP address of the interface the probe packet is sent on. If the IP address is not one of this machine's interface addresses, an error is returned and nothing is sent. A zero length octet string value for this object disables source address specification. The address type (InetAddressType) that relates to this object is specified by the corresponding value of traceRouteCtlSourceAddressType. read-write current 1.3.6.1.2.1.81.1.2.1.14 Setting this object to an interface's ifIndex prior to starting a remote traceroute operation directs the traceroute probes to be transmitted over the specified interface. A value of zero for this object implies that this option is not enabled. "d" read-write current 1.3.6.1.2.1.81.1.2.1.15 Enables an application to specify implementation dependent options. "255t" read-write current 1.3.6.1.2.1.81.1.2.1.16 "timeouts" The value of this object indicates the maximum number of consecutive timeouts allowed before terminating a remote traceroute request. A value of either 255 (maximum hop count/possible TTL value) or a 0 indicates that the function of terminating a remote traceroute request when a specific number of successive timeouts are detected is disabled. read-write current 1.3.6.1.2.1.81.1.2.1.17 This object enables setting of the don't fragment flag (DF) in the IP header for a probe. Use of this object enables performing a manual PATH MTU test. 1 2 read-write current 1.3.6.1.2.1.81.1.2.1.18 The value of this object specifies the initial TTL value to use. This enables bypassing the initial (often well known) portion of a path. read-write current 1.3.6.1.2.1.81.1.2.1.19 "seconds" The number of seconds to wait before repeating a traceroute test as defined by the value of the various objects in the corresponding row. The number of hops in a single traceroute test is determined by the value of the corresponding traceRouteCtlProbesPerHop object. After a single test completes the number of seconds as defined by the value of traceRouteCtlFrequency MUST elapse before the next traceroute test is started. A value of 0 for this object implies that the test as defined by the corresponding entry will not be repeated. read-write current 1.3.6.1.2.1.81.1.2.1.20 The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. 1 -- eh? 2 -- e.g., in RAM 3 -- e.g., in NVRAM 4 -- e.g., partially in ROM 5 -- e.g., completely in ROM read-write current 1.3.6.1.2.1.81.1.2.1.21 Reflects the desired state that an traceRouteCtlEntry should be in: enabled(1) - Attempt to activate the test as defined by this traceRouteCtlEntry. disabled(2) - Deactivate the test as defined by this traceRouteCtlEntry. Refer to the corresponding traceRouteResultsOperStatus to determine the operational state of the test defined by this entry. 1 -- operation should be started 2 -- operation should be stopped read-write current 1.3.6.1.2.1.81.1.2.1.22 The purpose of this object is to provide a descriptive name of the remote traceroute test. "255t" read-write current 1.3.6.1.2.1.81.1.2.1.23 "rows" The maximum number of entries allowed in the traceRouteProbeHistoryTable. An implementation of this MIB will remove the oldest entry in the traceRouteProbeHistoryTable to allow the addition of an new entry once the number of rows in the traceRouteProbeHistoryTable reaches this value. Old entries are not removed when a new test is started. Entries are added to the traceRouteProbeHistoryTable until traceRouteCtlMaxRows is reached before entries begin to be removed. A value of 0 for this object disables creation of traceRouteProbeHistoryTable entries. read-write current 1.3.6.1.2.1.81.1.2.1.24 The value of this object determines when and if to to generate a notification for this entry: pathChange(0) - Generate a traceRoutePathChange notification when the current path varies from a previously determined path. testFailure(1) - Generate a traceRouteTestFailed notification when the full path to a target can't be determined. testCompletion(2) - Generate a traceRouteTestCompleted notification when the path to a target has been determined. The value of this object defaults to zero, indicating that none of the above options have been selected. 0 1 2 read-write current 1.3.6.1.2.1.81.1.2.1.25 The current path for a traceroute test is kept in the traceRouteHopsTable on a per hop basis when the value of this object is true(1). 1 2 read-write current 1.3.6.1.2.1.81.1.2.1.26 The value of this object is used either to report or select the implementation method to be used for performing a traceroute operation. The value of this object may be selected from traceRouteImplementationTypeDomains. Additional implementation types should be allocated as required by implementers of the DISMAN-TRACEROUTE-MIB under their enterprise specific registration point and not beneath traceRouteImplementationTypeDomains. read-write current 1.3.6.1.2.1.81.1.2.1.27 This object allows entries to be created and deleted in the traceRouteCtlTable. Deletion of an entry in this table results in all corresponding (same traceRouteCtlOwnerIndex and traceRouteCtlTestName index values) traceRouteResultsTable, traceRouteProbeHistoryTable, and traceRouteHopsTable entries being deleted. A value MUST be specified for traceRouteCtlTargetAddress prior to a transition to active(1) state being accepted. Activation of a remote traceroute operation is controlled via traceRouteCtlAdminStatus and not by transitioning of this object's value to active(1). Transitions in and out of active(1) state are not allowed while an entry's traceRouteResultsOperStatus is active(1) with the exception that deletion of an entry in this table by setting its RowStatus object to destroy(6) will stop an active traceroute operation. The operational state of an traceroute operation can be determined by examination of the corresponding traceRouteResultsOperStatus object. 1 2 -- the following value is a state: -- this value may be read, but not written 3 -- the following three values are -- actions: these values may be written, -- but are never read 4 5 6 read-only current 1.3.6.1.2.1.81.1.3.1.1 Reflects the operational state of an traceRouteCtlEntry: enabled(1) - Test is active. disabled(2) - Test has stopped. 1 -- test is in progress 2 -- test has stopped read-only current 1.3.6.1.2.1.81.1.3.1.2 "hops" Reflects the current TTL value (range from 1 to 255) for a remote traceroute operation. Maximum TTL value is determined by traceRouteCtlMaxTtl. read-only current 1.3.6.1.2.1.81.1.3.1.3 "probes" Reflects the current probe count (1..10) for a remote traceroute operation. The maximum probe count is determined by traceRouteCtlProbesPerHop. read-only current 1.3.6.1.2.1.81.1.3.1.4 This objects indicates the type of address stored in the corresponding traceRouteResultsIpTgtAddr object. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-only current 1.3.6.1.2.1.81.1.3.1.5 This objects reports the IP address associated with a traceRouteCtlTargetAddress value when the destination address is specified as a DNS name. The value of this object should be a zero length octet string when a DNS name is not specified or when a specified DNS name fails to resolve. read-only current 1.3.6.1.2.1.81.1.3.1.6 "tests" The current number of attempts to determine a path to a target. The value of this object MUST be started at 0. read-only current 1.3.6.1.2.1.81.1.3.1.7 "tests" The current number of attempts to determine a path to a target that have succeeded. The value of this object MUST be reported as 0 when no attempts have succeeded. read-only current 1.3.6.1.2.1.81.1.3.1.8 The date and time when the last complete path was determined. "2d-1d-1d,1d:1d:1d.1d,1a1d:1d" read-only current 1.3.6.1.2.1.81.1.4.1.4 This objects indicates the type of address stored in the corresponding traceRouteProbeHistoryHAddr object. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-only current 1.3.6.1.2.1.81.1.4.1.5 The address of a hop in a traceroute path. This object is not allowed to be a DNS name. The value of the corresponding object, traceRouteProbeHistoryHAddrType, indicates this object's IP address type. read-only current 1.3.6.1.2.1.81.1.4.1.6 "milliseconds" The amount of time measured in milliseconds from when a probe was sent to when its response was received or when it timed out. The value of this object is reported as 0 when it is not possible to transmit a probe. read-only current 1.3.6.1.2.1.81.1.4.1.7 The result of a traceroute operation made by a remote host for a particular probe. 1 2 3 4 5 6 7 8 9 10 11 read-only current 1.3.6.1.2.1.81.1.4.1.8 The last implementation method specific reply code received. Traceroute is usually implemented by transmitting a series of probe packets with increasing time-to-live values. A probe packet is a UDP datagram encapsulated into an IP packet. Each hop in a path to the target (destination) host rejects the probe packets (probe's TTL too small, ICMP reply) until either the maximum TTL is exceeded or the target host is received. read-only current 1.3.6.1.2.1.81.1.4.1.9 Timestamp for when this probe results were determined. "2d-1d-1d,1d:1d:1d.1d,1a1d:1d" read-only current 1.3.6.1.2.1.81.1.5.1.2 This objects indicates the type of address stored in the corresponding traceRouteHopsIpTargetAddress object. 0 1 -- these named numbers are aligned 2 -- with AddressFamilyNumbers from 16 -- IANA-ADDRESS-FAMILY-NUMBERS-MIB read-only current 1.3.6.1.2.1.81.1.5.1.3 This object reports the IP address associated with the hop. A value for this object should be reported as a numeric IP address and not as a DNS name. read-only current 1.3.6.1.2.1.81.1.5.1.4 The minimum traceroute round-trip-time (RTT) received for this hop. A value of 0 for this object implies that no RTT has been received. read-only current 1.3.6.1.2.1.81.1.5.1.5 The maximum traceroute round-trip-time (RTT) received for this hop. A value of 0 for this object implies that no RTT has been received. read-only current 1.3.6.1.2.1.81.1.5.1.6 The current average traceroute round-trip-time (RTT) for this hop. read-only current 1.3.6.1.2.1.81.1.5.1.7 This object contains the sum of all traceroute responses received for this hop. Its purpose is to enable standard deviation calculation. read-only current 1.3.6.1.2.1.81.1.5.1.8 The value of this object reflects the number of probes sent for this hop during this traceroute test. The value of this object should start at 0. read-only current 1.3.6.1.2.1.81.1.5.1.9 Number of responses received for this hop during this traceroute test. This value of this object should start at 0. read-only current 1.3.6.1.2.1.81.1.5.1.10 Date and time was the last response was received for a probe for this hop during this traceroute test.
