User view
Parameter
HH:MM:SS:
Current time, where HH ranges from 0 to 23, MM and SS
range from 0 to 59.
YYYY/MM/DD
or MM/DD/YYYY: Current date, where YYYY represents year ranging
from 2000 to 2099, MM represents month ranging from 1 to 12, and DD

In an implementation where exact absolute
time is required, it is necessary to use this command to set the current date
and time of the Ethernet switch.
Related command: display clock.

all: Specifies
to disable all debugging.
Description
Use the debugging command to enable
system debugging.
Use the undo debugging command to
disable system debugging.
By default, all debugging is disabled for
the system.
Note that:
l
Enabled debugging will generate a great deal of
debugging information and thus will affect the efficiency of the system.
Therefore, it is recommended not to enable debugging for multiple functions at
the same time. To disable all debugging at a time, you can use the undo
debugging all command.
l
The specific debugging information can be
displayed on a terminal only after you have configured the debugging, terminal
debugging, and terminal monitor commands.
l
To display the enabled debugging types, use the display
debugging command.
For information about the terminal
monitor command, refer to Information Center Command.

Use the undo terminal debugging
command to disable terminal display for debugging information.
By default, terminal display for debugging
information is disabled.
Note that:
l
To display the debugging information on the
terminal, you need to configure both the terminal debugging and terminal
monitor commands.
l
If you execute the undo terminal monitor command,
you will disable the monitoring of the log, trap, and debugging information on
the current terminal. Thereby, no log, trap, or debugging information will be
displayed on the terminal.

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 IP
network connectivity and the reachability of a host.
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.

] [ -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 device to the
destination device. 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.
