Ping Test

Ping tests detect the connectivity between the source and sink of a tunnel.

Navigation Path

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 > Ping Test.

Parameters

**Table 1** Descriptions of the parameters for Ping Test
Field	Value	Description
Packet Count	Example: 3	Set the count of packets.
EXP Value	0-7	Set the EXP value. The packet priority increases with the EXP value.
TTL	1-255	Sets the live of detection packets. Each time when the detection packets traverse an NE, the TTL value is decreased by 1. When the TTL value is decreased to 0, the detection packets are discarded.
Transmit Interval (10ms)	10-1000	Set the interval for transmitting detection packets.
Packet Length	65-1400	Set the length of packets (step: 4).
Wait-to-Response Timeout Time (10ms)	50-6000	After the local end sends detection packets, if the local end does not receive the respond packets from the opposite end within the set response timeout period, it indicates that the link fails. NOTE: The value range of the response timeout period varies according to the NE type. If the response timeout period is beyond the range, an error message is displayed on the NMS.
Response Mode	No Response, IPv4 UDP Response, Application Control Channel	IPv4 UDP Response: The source NE sends ping packets. The sink NE returns response packets to the source NE through the dynamic link. The source NE reports the ping test result. When you select IPv4 UDP Response, the protocol of ISIS must be enabled. No Response: The source NE sends ping packets. The sink NE does not return response packets to the source NE after receiving the ping packets. Instead, the sink NE reports the ping test result. Application Control Channel: The source NE sends ping packets. The sink NE returns response packets through the static reverse tunnel. The source NE reports the ping test result. NOTE: Set Response Mode according to the following rules: If the tunnel is a unidirectional static tunnel, setting Response Mode to No Response is recommended. If the tunnel is a bidirectional static tunnel, setting Response Mode to Application Control Channel is recommended. If the tunnel is a dynamic tunnel, setting Response Mode to IPv4 UDP Response is recommended.
Test Result	Character string	Display the test result.
