ping

Syntax

ping [ -a ip-address ] [ -c count ] [ -d ] [ -f ] [ -h ttl ] [ -i interface-type interface-number ] [ ip ] [ -n ] [ - p pattern ] [ -q ] [ -s packetsize ] [ -t timeout ] [ -tos tos ] [ -v ] host

View

Any view

Parameter

-a ip-address: Specifies the source IP address to send ICMP ECHO-REQUEST packet. This IP address must be a local interface IP address.

-c count: Specifies how many times the ICMP ECHO-REQUEST packet will be sent. The count argument is the times, which ranges from 1 to 4,294,967,295 and defaults to 5.

-d: Specifies the socket to be in DEBUGGING mode. By default, the socket is in non-DEBUGGING mode.

-f: Specifies to discard a packet directly instead of fragmenting it if its length is greater than the maximum transmission unit (MTU) of the interface.

-h ttl: Specifies the time to live (TTL) value of the ICMP ECHO-REQUEST packets in the range 1 to 255. By default, the TTL value is 255.

-i interface-type interface-number: Specifies the interface that sends ICMP ECHO-REQUEST packets by its interface type and number. After the interface is specified, the TTL of the ICMP ECHO-REQUEST packet is set to 1 to test the directly-connected device (the IP address of the device is in the same network segment as that of the interface).

ip: Specifies the device to support IPv4. By default, the device supports IPv4.

-n: Specifies to directly regard the host argument as an IP address without performing domain name resolution. By default, the host argument is first regarded as an IP address; if it is not an IP address, domain name resolution is performed.

-p pattern: Specifies the padding byte pattern of the ICMP ECHO-REQUEST packets. The pattern argument is a byte in hexadecimal. For example, -p ff fills a packet with all ffs. By default, the system fills a packet with 0x01, 0x02, and so on, until 0x09; then it repeats this procedure from 0x01 again.

-q: Specifies to display only the statistics without the details. By default, all the information including the details and statistics will be displayed.

-s packetsize: Specifies the size (in bytes) of each ICMP ECHO-REQUEST packet (excluding the IP and ICMP headers). The packetsize argument ranges from 20 to 32,000 and defaults to 56 bytes.

-t timeout: Specifies the timeout time (in milliseconds) before an ICMP ECHO-REPLY packet is received after an ICMP ECHO-REQUEST packet is sent. The timeout argument ranges from 0 to 65535 ms and defaults to 2,000 ms.

-tos tos: Specifies the ToS value of the ICMP ECHO-REQUEST packets in the range 0 to 255. By default, this value is 0.

-v: Specifies to display other ICMP packets received (that is, non-ECHO-REPLY packets). By default, other ICMP packets like non-ECHO-REPLY packets are not displayed.

host: Domain name or IP address of the destination host.

Description

Use the ping command to check the reachability of a host, and output the related statistics information.

The executing procedure of the ping command is as follows: First, the source host sends an ICMP ECHO-REQUEST packet to the destination host. If the connection to the destination network is normal, the destination host receives this packet and responds with an ICMP ECHO-REPLY packet.

You can use the ping command to check the network connectivity and the quality of a network line. This command can output the following information:

l Response status of the destination to each ICMP ECHO-REQUEST packet, including the number of bytes, packet sequence number, TTL and response time of the response packet if the response packet is received within the timeout time. If no response packet is received within the timeout time, the message "Request time out" is displayed instead.

l Final statistics, including the numbers of sent packets and received response packets, the irresponsive packet percentage, and the minimum, average and maximum values of response time.

You can set a relatively long timeout time if the network transmission speed is slow.

Related command: tracert.

Example

# Check the reachability of the host whose IP address is 202.38.160.244.

<Sysname> ping 202.38.160.244

ping 202.38.160.244 : 56 data bytes, press CTRL_C to break

Reply from 202.38.160.244 : bytes=56 sequence=1 ttl=255 time = 1ms

Reply from 202.38.160.244 : bytes=56 sequence=2 ttl=255 time = 2ms

Reply from 202.38.160.244 : bytes=56 sequence=3 ttl=255 time = 1ms

Reply from 202.38.160.244 : bytes=56 sequence=4 ttl=255 time = 3ms

Reply from 202.38.160.244 : bytes=56 sequence=5 ttl=255 time = 2ms

--202.38.160.244 ping statistics--

5 packet transmitted

5 packet received

0% packet loss

round-trip min/avg/max = 1/2/3 ms

The above output information indicates that the destination host is reachable. Each probe packet from the source device has got a reply, with the minimum/average/maximum packet roundtrip time being 1ms/2ms/3ms.

tracert

Syntax

tracert [ -a source-ip ] [ -f first-ttl ] [ -m max-ttl ] [ -p port ] [ -q num-packet ] [ -w timeout ] string

View

Any view

Parameter

-a source-ip: Specifies the source interface IP address used by this command.

-f first-ttl: Specifies the initial TTL value of the packets to be sent, so as to only display the addresses of those gateways on the path whose hop counts are not smaller than the hop count specified by the first-ttl argument. For example, if the first-ttl argument is 3, the command displays the addresses of the gateways from the third hop. The first-ttl argument ranges from 1 to 255 and defaults to 1.

-m max-ttl: Specifies the maximum TTL value of the packets to be sent. After the command sends a packet with the maximum TTL, it will not send any more packets. With this argument, this command only displays the addresses of those gateways from the source address to hop according to the hop count specified by the argument. For example, if the max-ttl argument is 5, the command displays the addresses of the gateways from the source to the fifth hop. The max-ttl argument ranges from 1 to 255 and defaults to 30.

-p port: Specifies the destination port of the packets to be sent. The port argument ranges from 0 to 65535 and defaults to 33434. Generally, you need not change the argument.

-q num-packet: Specifies the number of packets to be sent each time. The num-packet argument ranges from 0 to 65,535 and defaults to 3.

-w timeout: Specifies the timeout time to wait for ICMP error packets. The timeout argument ranges from 0 to 65,535 and defaults to 5,000 (in milliseconds).

string: IP address of the destination host, or host name of the remote system with 1 to 20 characters.

Description

Use the tracert command to trace the gateways that the test packets pass through from the source to the destination. This command is mainly used to check the network connectivity and help locate the network faults.

The executing procedure of the tracert command is as follows: First, the source sends a packet with the TTL of 1, and the first hop device returns an ICMP error message indicating that it cannot forward this packet because of TTL timeout. Then, the source resends a packet with the TTL of 2, and the second hop device also returns an ICMP TTL timeout message. This procedure goes on and on until a packet gets to the destination or the maximum TTL is reached. During the procedure, the system records the source address of each ICMP TTL timeout message in order to offer the path that the packets pass through to the destination.

If you find that the network is faulty by using the ping command, you can use the tracert command to find where the fault is in the network.

The tracert command can output the IP addresses of all the gateways that the packets pass through to the destination. It outputs the string "***" if the response from a gateway times out.

Example

# Trace the gateways that the packets pass through to the destination with IP address 18.26.0.115.
