Release Information
Command introduced before JUNOSe Release 7.1.0.
vrf keyword and vrfName variable added to IPv6 version in JUNOSe Release 7.2.0.
Description
Sends an ICMP echo request packet to the IP or IPv6 address that you specify. There
is no
no version.
Options
■
vrfName —Name of the VRF context
■
ip—Specifies optional keyword for compatibility with non–E Series
implementations
■
ipv6—Specifies the destination address as IPv6 format
■
destination —IP address, IPv6 address, or domain name of the host to ping
■
packetCount —Number of packets to send to the destination IP address, in the
range 0–4294967295; default value is 5; 0 means ping forever
■
timeOutVal —Number of seconds, in the range 1–20, to wait for an ICMP echo
reply packet before the connection attempt times out
■
delayVal —Number of milliseconds, in the range 1–50, between transmission of
each ICMP request; default value is 10 ms
■
hopLimit —Specifies a hop limit, in the range 1–255; default value is 255
■
ttlValue —Specifies a hop count by setting the time-to-live field in the IP header
in the range 1–255; default value is 32
■
dataSize —Number of bytes comprising the IP packet and reflected in the IP
header, in the range 0–64000; default value is 100 bytes
■
data-pattern—Type of bits contained in the packet. You can set the bits to all
ones, all zeros, a random mixture of ones and zeros, or a specific hexadecimal
data pattern that can range from 0x0 – 0xFFFFFFFF. The default data pattern is
all zeros.
