Parameters
ip: Distinguishes between a destination host name and the ping command keywords if the name of the
destination host is i, ip, ipv, or ipv6. For example, you must use the command in the form of ping ip ip
instead of ping ip if the destination host name is ip.
-a source-ip: Specifies an IP address of the device as the source IP address of ICMP echo requests. If this
option is not specified, the source IP address of ICMP echo requests is the primary IP address of the
outbound interface.
-c count: Specifies the number of ICMP echo requests that are sent to the destination. The value range is
1 to 4294967295, and the default is 5.
-f: Sets the DF bit in the IP header.
-h ttl: Specifies the TTL value of ICMP echo requests. The value range is 1 to 255, and the default is 255.
-i interface-type interface-number: Specifies the ICMP echo request sending interface by its type and
number. If this parameter is not provided, the ICMP echo request sending interface is determined by
searching the routing table or forwarding table according to the destination IP address.
-m interval: Specifies the interval (in milliseconds) to send ICMP echo requests. The value range is 1 to
65535, and the default is 200.
• If a response from the destination is received within the timeout time, the interval to send the next
echo request equals the actual response period plus the value of interval.
• If no response from the destination is received within the timeout time, the interval to send the next
echo request equals the timeout value plus the value of interval.
-n: Disables domain name resolution for the host argument. When this keyword is not provided, if the
host argument represents the host name of the destination, the device translates host into an address.
