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
detail Displays detailed information about MPLS echo request sent and echo
replies received
