By default, for Cisco devices, the MPLS Topology Server includes the following command options in the LSP ping command lines that it constructs and invokes for LSP ping server tool invocations:

         ping mpls ipv4 <destination-address destination-mask> [repeat 5] 
   [timeout 2] [size 100] [interval 0]

Here is an example of an LSP ping command line and the ping test results. The remote computer shell prompt “Router#” indicates that the MPLS Topology Server has established a Telnet, SSH1, or SSH2 session with the originating device.

dev-VPLS5#ping mpls ipv4 repeat 5 timeout 2 size 100 interval 0
Sending 5, 100-byte MPLS Echos to, 
     timeout is 2 seconds, send interval is 0 msec:
Codes: '!' - success, 'Q' - request not sent, '.' - timeout,
  'L' - labeled output interface, 'B' - unlabeled output interface, 
  'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch,
  'M' - malformed request, 'm' - unsupported tlvs, 'N' - no label entry, 
  'P' - no rx intf label prot, 'p' - premature termination of LSP, 
  'R' - transit router, 'I' - unknown upstream index,
  'X' - unknown return code, 'x' - return code 0
Type escape sequence to stop.
Success rate is 0 percent (0/5)
