size octets  — The  OAM request packet size in octets, expressed as a decimal integer. 
min-ttl vc-label-ttl — The minimum TTL value in the VC label for the trace test, expressed as a 
decimal integer.
Default 1
Values 1 — 255
max-ttl vc-label-ttl — The maximum TTL value in the VC label for the trace test, expressed as a 
decimal integer.

return-control — Specifies the OAM reply to a data plane OAM request be sent using the control 
plane instead of the data plane.
Default OAM reply sent using the data plane.
probe-count send-count — The number of OAM requests sent for a particular TTL value, expressed 
as a decimal integer.
Default 1
Values 1 — 10
interval seconds — The interval parameter in seconds, expressed as a decimal integer. This 
parameter is used to override the default request message send interval and defines the minimum 
amount of time that must expire before the next message request is sent. 
If the interval is set to 1 second where the timeout value is set to 10 seconds, then the maximum 
time between message requests is 10 seconds and the minimum is 1 second. This depends upon 
the receipt of a message reply corresponding to the outstanding message request.
Default 1
Values 1 — 10
timeout timeout — The timeout parameter in seconds, expressed as a decimal integer. This value is 
used to override the default timeout value and is the amount of time that the router will wait for 
a message reply after sending the message request. Upon the expiration of message timeout, the 
requesting router assumes that the message response will not be received. Any response received 
after the request times out will be silently discarded.
