Run a Traceroute Test

About this task

Run a traceroute test to determine the route packets take through a network to a destination.

Note

Troubleshooting using ping and traceroute (including Layer 2 ping and Layer 2 traceroute) is not supported on EDM. For more information, see VSP 8600 Release Notes. As an alternative, use CLI.

Procedure

From the navigation pane, expand Configuration > Edit > Diagnostics.
Click Ping/Trace Route.
Click the Trace Route Control tab.
Click Insert.
Configure the instance as required.
Click Insert.
Select an entry, and then click Start.

Let the test run for several seconds.
Select an entry, and then click Stop.
View the traceroute test results.

Trace Route Control Field Descriptions

Use the data in the following table to use the Trace Route Control tab.


Name	Description
OwnerIndex	Provides access control by a security administrator using the VACM for tables in which multiple users need to independently create or modify entries.
TestName	Specifies the name of the traceroute test.
TargetAddressType	Specifies the type of host address to use on the traceroute request at the remote host. The default is IPv4.
TargetAddress	Specifies the host address used on the traceroute request at the remote host.
ByPassRouteTable	Enables bypassing of the route table. If you enable this variable, the remote host bypasses the normal routing tables and sends directly to a host on an attached network. If the host is not on a directly-attached network, an error is returned. You can use this variable to perform the traceroute operation to a local host through an interface that has no route defined. The default is disabled.
DataSize	Specifies the size of the data portion of a traceroute request in octets. The default is 1.
TimeOut	Specifies the timeout value, in seconds, for a traceroute request. The default is 3.
ProbesPerHop	Specifies the number of times to reissue a traceroute request with the same time-to-live (TTL) value. The default is 3.
Port	Specifies the UDP port to which to send the traceroute request. Specify a port that is not in use at the destination (target) host. The default is the IANA assigned port 33434. Note: If the traceroute action is directed to an IPv6 host address, Linux increments the UDP port on a per-TTL basis. For an IPv4 host address, Linux increments the UDP port on a per-probe basis. Because the traceroute command sends a default of three probes, three incrementing ports will be sent for an IPv4 host address. If you use the -p parameter with a value greater than 65533, the traceroute command fails for an IPv4 host address because the maximum port number, 65535, is exceeded.
MaxTtl	Specifies the maximum time-to-live from 1–255. The default is 30.
DSField	Specifies the value to store in the Differentiated Services (DS) field in the IP packet used to encapsulate the traceroute probe. The default is 0.
SourceAddressType	Specifies the type of the source address to use at a remote host.
SourceAddress	Uses the specified IP address (which must be an IP number, not a hostname) as the source address in outgoing probe packets.
IfIndex	Directs the traceroute probes to be transmitted over the specified interface. The default is 0.
MiscOptions	Enables an application to specify implementation-dependent options.
MaxFailures	Indicates the maximum number of consecutive timeouts allowed before terminating a remote traceroute request. The default is 5.
DontFragment	Enables setting of the do not fragment (DF) flag in the IP header for a probe. The default is disabled.
InitialTtl	Specifies the initial time-to-live (TTL) value to use. The default is 1.
Frequency	Specifies 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 default is 0.
StorageType	Specifies the storage type for this row.
AdminStatus	Specifies the desired state for TraceRouteCtlEntry. The options are enabled or disabled. The default is disabled.
MaxRows	Specifies the maximum number of entries allowed in the TraceRouteProbeHistoryTable. The default is 50.
TrapGeneration	Determines when to generate a notification for this entry. The options are pathChange —Generates a TraceRoutePathChange notification after the current path varies from a previously determined path. testFailure —Generates a TraceRouteTestFailed notification after the full path to a target cannot be determined. testCompletion —Generates a TraceRouteTestCompleted notification after the path to a target has been determined.
Descr	Describes the remote traceroute test.
CreateHopsEntries	Stores the current path for a traceroute test in the TraceRouteHopsTable on an individual hop basis when the value of this object is true. The default is false.
Type	Reports or selects the implementation method to use for performing a traceroute operation.
