1Ping, tracert, and system debuggingcommandsPing and tracert commandspingUse ping to verify whether the destination in an IP network is reachable, and to display the relatedstatistics.Syntaxping [ ip ] [ -a source-ip | -c count | -f | -h ttl | -i interface-type interface-number | -m interval | -n | -ppad | -q | -r | -s packet-size | -t timeout | -tos tos | -v |-vpn-instance vpn-instance-name ] * hostViewsAny viewDefault command level0: Visit levelParametersip: Supports IPv4 protocol. If this keyword is not provided, IPv4 is also supported.-a source-ip: Specifies the source IP address of an ICMP echo request (ECHO-REQUEST). It must be anIP address configured on the device. If this parameter is not provided, the source IP address of an ICMPecho request is the primary IP address of the outbound interface of the request.-c count: Specifies the number of times that an ICMP echo request is sent, which ranges from 1 to4294967295 and defaults to 5.-f: Discards packets larger than the MTU of a given interface, which means the ICMP echo request is notallowed to be fragmented.-h ttl: Specifies the TTL value for an ICMP echo request, which ranges from 1 to 255 and defaults to 255.-i interface-type interface-number: Specifies the ICMP echo request sending interface by its type andnumber. If this parameter is not provided, the ICMP echo request sending interface is determined bysearching 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, which ranges from 1 to65535 and defaults to 200.• If a response from the destination is received within the timeout time, the interval to send the nextecho 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 nextecho 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 thehost argument represents the host name of the destination, the device translates host into an address.
