Traceroute Test

Detects the connectivity between any two neighboring nodes on a tunnel. A traceroute test checks the node connectivity by returning the response packets of each node on the tunnel.

Navigation Path

In the NE Explorer, click the NE and choose Configuration > Packet Configuration > MPLS Management > Unicast Tunnel Management from the Function Tree. Then, click the OAM Parameters tab and choose OAM Operation > Traceroute Test.

For RTN NEs, in the NE Explorer, click the NE and choose Configuration > MPLS Management > Unicast Tunnel Management from the Function Tree. Then, click the OAM Parameters tab and choose OAM Operation > Traceroute Test.

Parameter Description

**Table 1** Parameters for traceroute tests
Parameter	Value	Description
EXP Value	0-7	Indicates the EXP value. The packet priority increases with the EXP value.
TTL	1-255	Indicates the TTL.
Packet Length	89-1400	Indicates the length of packets (step: 4).
Wait-to-Response Timeout Time (10ms)	1-6000	Indicates the wait-to-response timeout time. NOTE: Different NEs support the different ranges of wait-to-response timeout time. When the value exceeds the range, an error message is displayed.
Response Mode	No Response, IPv4 UDP Response, Application Control Channel	Indicates the response mode.
Tunnel ID	Example: 1	Indicates the tunnel ID.
Replier	Example: 1.1.12.238	Indicates the LSR ID of the replier.
Delay(us)	Example: 3455	Indicates the delay in response.
Type	ingress, transit, egress	Indicates the node type. The options are as follows: ingress: source node transit: transit node egress: sink node
Downstream LSR ID	Example: 1.1.12.238	Indicates the downstream LSR ID. If there is no downstream LSR ID, the value will be none.
Downstream Label	Example: 25	Indicates the downstream label. If there is no downstream label, the value will be none.
Test Result	Response, Overtime	Indicates the test result.
