-h ttl: Specifies the TTL value for an ICMP echo request. The ttl argument is in the range of 1 to 255. The default value is 255. -i interface-type interface-number: Specifies the ICMP echo request sending interface by its type and number. If this option 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 an ICMP echo request. The interval argument is in the range of 1 to 65535. The default value is 200. -n: Disables domain name resolution for the host argument. If the host argument represents the host name for the destination, and this keyword is not specified, the device translates host into an address. -p pad: Specifies the value of the pad field in an ICMP echo request, in hexadecimal format, 1 to 8 bits.The pad argument is in the range of 0 to ffffffff. If the specified value is less than 8 bits, 0s are added in front of the value to extend it to 8 bits. For example, if pad is configured as 0x2f, then the packets are padded with 0x0000002f to make the total length of the packet meet the requirements of the device. By default, the padded value starts from 0x01 up to 0xff, where another round starts again if necessary, like 0x010203...feff01.... -q: Displays only statistics. If this keyword is not specified, the system displays all information. -r: Records routing information. If this keyword is not specified, routes are not recorded. -s packet-size: Specifies length (in bytes) of an ICMP echo request (not including the IP packet header and the ICMP packet header). The packet-size argument is in the range of 20 to 8100. The default value is 56. -t timeout: Specifies the timeout time (in milliseconds) of an ICMP echo reply. If the source does not receive an ICMP echo reply within the timeout, it considers the ICMP echo reply timed out. The timeout argument is in the range of 0 to 65535. The default value is 2000. -tos tos: Specifies the ToS value of an ICMP echo request. The tos argument is in the range of 0 to 255. The default value is 0. -v: Displays non ICMP echo reply received. If this keyword is not specified, the system does not display non ICMP echo reply. -vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the destination belongs, where the vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this option. host: IP address or host name (a string of 1 to 253 characters) for the destination. Usage guidelines To use the name of the destination host to perform the ping operation, you must first configure the DNS on the device. Otherwise, the ping operation will fail. To abort the ping operation during the execution of the command, press Ctrl+C. Examples # Test whether the device with an IP address of 1.1.2.2 is reachable. ping 1.1.2.2 PING 1.1.2.2 (1.1.2.2): 56 data bytes, press CTRL_C to break 56 bytes from 1.1.2.2: icmp_seq=0 ttl=254 time=2.137 ms 56 bytes from 1.1.2.2: icmp_seq=1 ttl=254 time=2.051 ms 56 bytes from 1.1.2.2: icmp_seq=2 ttl=254 time=1.996 ms 56 bytes from 1.1.2.2: icmp_seq=3 ttl=254 time=1.963 ms 7
