packetCount—Number of packets to send to the destination address, in the range
0–4294967295; default value is 5; 0 means ping forever
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
dataSize—Number of bytes comprising the MPLS packet, including the header, in the
range 0–64000; default value is 100 bytes
sweep-sizes—Configures payload sizes, enabling you to vary the sizes of the echo
packets being sent. This capability is useful for determining the minimum sizes of the
MTUs configured on the nodes along the path to the destination address. This reduces
packet fragmentation which contributes to performance problems. The default is not
to sweep; all packets are the same size.
sweepMin—Minimum payload size in the range 0–64000
sweepMax—Maximum payload size in the range 0–64000
sweepInt—Number of bytes to add to the size of the packet; the change in the size
of subsequent ping packets while sweeping across a range of sizes. For example,
you can configure the sweep interval to sweep across the range of packets from 0
bytes to 10,000 bytes in increments of sweepInt. By default, send 100, 101, 102,
103...1000. If sweepInt is 5, send 100, 105, 110, 115...1000). When " sweeping," the
default interval is 1.
pad—Specifies the type of bits contained in the pad TLV. You can set the bits to all
ones, all zeros, a random mixture of ones and zeros, or a specific hexadecimal data
pattern, in the range from 0x0–0xFFFFFFFF. The default data pattern is all zeros.
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
txDelayVal—Number of milliseconds in the range 1–50 between transmission of each
echo request; default value is 10 ms
bitValue—Value of the EXP bits in the range 0–7 included in the MPLS echo request
packet
bottomLabelTtl—Time-to-live value of the bottom label in the stack
detail—Displays detailed information about MPLS echo request sent and echo replies
