"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 3415, VACM) and that allows a management application to identify its entries. The second index, traceRouteCtlTestName (also an SnmpAdminString), enables the same management application to have multiple requests outstanding."

MAX-ACCESS not-accessible STATUS current DESCRIPTION "To facilitate the provisioning of access control by a security administrator using the View-Based Access Control Model (RFC 3415, VACM) for tables in which multiple users may need to create or modify entries independently, the initial index is used as an 'owner index'. Such an initial index has a syntax of SnmpAdminString and can thus be trivially mapped to a securityName or groupName defined in VACM, in accordance with a security policy. When used in conjunction with such a security policy, all entries in the table belonging to a particular user (or group) will have the same value for this initial index. For a given user's entries in a particular table, the object identifiers for the information in these entries will have the same subidentifiers (except for the 'column' subidentifier) up to the end of the encoded owner index. To configure VACM to permit access to this portion of the table, one would create vacmViewTreeFamilyTable entries with the value of vacmViewTreeFamilySubtree including the owner index portion, and vacmViewTreeFamilyMask 'wildcarding' the column subidentifier. More elaborate configurations are possible." ::= { traceRouteCtlEntry 1 } traceRouteCtlTestName OBJECT-TYPE SYNTAX SnmpAdminString (SIZE(0..32)) MAX-ACCESS not-accessible STATUS current DESCRIPTION "The name of a traceroute test.

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 the routing daemon at the host)." DEFVAL { false } ::= { traceRouteCtlEntry 5 } traceRouteCtlDataSize OBJECT-TYPE SYNTAX Unsigned32 (0..65507) UNITS "octets" MAX-ACCESS read-create STATUS current DESCRIPTION "Specifies the size of the data portion of a traceroute request, in octets. If the RECOMMENDED traceroute method (UDP datagrams as probes) is used, then the value contained in this object MUST be applied. If another traceroute method is used for which the specified size is not appropriate, then the implementation SHOULD use whatever size (appropriate to the method) is closest to the specified size.
The maximum value for this object was computed by subtracting the smallest possible IP header size of 20 octets (IPv4 header with no options) and the UDP header size of 8 octets from the maximum IP packet size.

The octet to be set in the IP header contains the Differentiated Services (DS) Field in the six most significant bits. 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. A value of 0 means that the function represented by this option is not supported. DS Field usage is often not supported by IP implementations, and not all values are supported. Refer to RFC 2474 and RFC 3260 for guidance on usage of this field."

traceRouteCtlSourceAddress OBJECT-TYPE SYNTAX InetAddress MAX-ACCESS read-create STATUS current DESCRIPTION "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 select the address to be used. 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." DEFVAL { ''H } ::= { traceRouteCtlEntry 13 } traceRouteCtlIfIndex OBJECT-TYPE SYNTAX InterfaceIndexOrZero MAX-ACCESS read-create STATUS current DESCRIPTION "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.

"The value of this object indicates the maximum number of consecutive timeouts allowed before a remote traceroute request is terminated. A value of either 255 (maximum hop count/possible TTL value) or 0 indicates that the function of terminating a remote traceroute request when a specific number of consecutive timeouts are detected is disabled."

After a single test is completed 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." DEFVAL { 0 } ::= { traceRouteCtlEntry 19 } traceRouteCtlStorageType OBJECT-TYPE SYNTAX StorageType MAX-ACCESS read-create STATUS current DESCRIPTION "The storage type for this conceptual row.

DEFVAL { ''H } ::= { traceRouteCtlEntry 22 }
traceRouteCtlMaxRows OBJECT-TYPE SYNTAX Unsigned32 UNITS "rows" MAX-ACCESS read-create STATUS current DESCRIPTION "The maximum number of corresponding entries allowed in the traceRouteProbeHistoryTable. An implementation of this MIB will remove the oldest corresponding entry in the traceRouteProbeHistoryTable to allow the addition of an new entry once the number of corresponding 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.

Deletion of an entry in this table results in a deletion of all corresponding (same traceRouteCtlOwnerIndex and traceRouteCtlTestName index values) traceRouteResultsTable, traceRouteProbeHistoryTable, and traceRouteHopsTable entries. A value MUST be specified for traceRouteCtlTargetAddress prior to acceptance of a transition to active(1) state.
When a value for pingCtlTargetAddress is set, the value of object pingCtlRowStatus changes from notReady(3) to notInService(2). 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.
