Command introduced in JunosE Release 8.0.0.
data-size keyword and dataSize variable added in JunosE Release 11.1.0.
Sends MPLS echo request packets with successively higher TTL values to the specified
layer 2 cross-connect virtual (Martini) circuit. Discovers the path MPLS packets follow
to the destination. There is no no version.
The echo request packet generated by this command contains the FEC 128 Pseudowire
(Current) sub-TLV described in RFC 4379—Detecting Multi-Protocol Label Switched
(MPLS) Data Plane Failures (February 2006).
NOTE: This command is not supported for local cross-connects because
local cross-connects do not employ an LSP.
vrfName—Name of the VRF context
interfaceType—Interface type; see Interface Types and Specifiers on page 5
interfaceSpecifier—Particular interface; format varies according to interface type; see
Interface Types and Specifiers on page 5
dataSize—Size of the LSP ping message (does not include the UDP, IP, and MPLS
headers of the packet); in the range 0–6400 bytes. The default value is 100 bytes.
startIpAddress—First IP address within the 127.0.0.0/8 destination range
endIpAddress—Last IP address within the 127.0.0.0/8 destination range
increment—Number in the range 0–255 that specifies the increment between addresses
in the destination address range
sourceAddr—IP address used as the packet source address
ttlValue—Hop count specified by setting the time-to-live field in the header, in the
range 1–255; default value is 32; however, by default, the TTL on the inner (stacked)
label is set to 1 while transmitting the echo request packet, which causes the packet
to be exceptioned to the SRP module when the stacked label is exposed
