Sends MPLS echo request packets with successively
higher TTL values to the specified IP or IPv6 address. Discovers the
path MPLS packets follow to the destination. There is no no version.
The MPLS echo request packets and echo reply packets created
by this command use the LDP IPv4 sub-TLV described in RFC 4379—Detecting
Multi-Protocol Label Switched (MPLS) Data Plane Failures (February
2006).
Options
vrfName—Name of the VRF context;
when you specify a VRF name, the LSP to the specified prefix must
originate from the VRF because the ping is generated from the specified
VRF
targetIpAddress—IP address
of the ping target
targetIpv4Mask—Network mask
for target IP address
targetIpv6Prefix—IPv6 address
of the ping target
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
timeOutVal—Number of seconds
in the range 1–32 to wait for an MPLS echo reply packet before
the connection attempt times out
reply mode—Specifies the reply mode for the echo
request packet
ipv4-udp—Specifies that the echo request packet
is an IPv4 UDP packet
ipv4-udp-with-router-alert—Specifies that the echo
request packet is an IPv4 UDP packet with the router alert bit set
in the header so all routers examine this packet more closely to determine
whether further processing is necessary
reply pad-tlv—Requests sender of an echo reply to
send a pad TLV
trafficClass—Number in the
range 0–255 that represents the value of the traffic class that
the sender of an echo reply is requested to set
bitValue—Value of the EXP
bits in the range 0–7 included in the MPLS echo request packet
detail—Displays detailed information about MPLS
echo request sent and echo replies received
