DISMAN-TRACEROUTE-MIB

1.3.6.1.2.1.81.1.1

traceRouteMaxConcurrentRequests

INTEGER (0..4294967295)

Read-write

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. The limit applies only to new requests being activated. When a new value is set, the agent will continue processing all the requests already active, even if their number exceeds the limit just imposed.

Value range for the number of test instances that can be configured: 0 to 5000.

1.3.6.1.2.1.81.1.2.1.1

traceRouteCtlOwnerIndex

Octets(0..32)

Not-accessible

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 independently create or modify entries, the initial index is used as an 'owner index'. Such an initial index has the SnmpAdminString syntax, and can thus be trivially mapped to a securityName or groupName as 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.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.81.1.2.1.2

traceRouteCtlByPassRouteTable

INTEGER{true(1),false(2)}

Read-create

The purpose of this object is to optionally enable bypassing the routing 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 (for example, after the interface was dropped by routed).

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.2.1.81.1.2.1.6

traceRouteCtlDataSize

Unsigned32 (0..65507)

Read-create

This object indicates the size of the data portion of a traceroute request in octets.

A traceroute request is essentially transmitted by encoding a UDP datagram into an IP packet. So subtracting the size of a UDP header (8 octets) and the size of an IP header (20 octets) yields the datasize of traceroute request.

The value ranges from 0 to 8100.

The DS Field is defined as the Type of Service (ToS) octet in an IPv4 header or as the Traffic Class octet in an IPv6 header. 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-only

1.3.6.1.2.1.81.1.2.1.12

1.3.6.1.2.1.81.1.2.1.13

traceRouteCtlSourceAddress

OCTET STRING (SIZE (0..255))

Read-create

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.

Only supports IPv4 and IPv6.

traceRouteCtlRowStatus

INTEGER{active(1),notInService(2),notReady(3),createAndGo(4),createAndWait(5),destroy(6)}

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 a traceroute operation can be determined by examination of the corresponding traceRouteResultsOperStatus object.
