1.3 System Debugging Commands
1.3.1 debugging
Syntax
debugging { all | timeout interval | module-name [ debugging-option ] }
undo debugging { all | module-name [ debugging-option ] }
View
User view
Parameters
all: Enables or disables all the debugging.
timeout interval: Specifies the interval (in minutes) during which the debugging all switch is on. The value ranges from 1 to 1440. With this configuration, all debugging takes the time at which it is enabled as the start time, and takes effect during the predefined time. And after that, all debugging is disabled.
module-name: Module name.
debugging-option: Debugging option.
Description
Use the debugging command to enable the system debugging.
Use the undo debugging command to disable the system debugging.
By default, all the debugging processes are disabled.
The switch provides various kinds of debugging functions for technical support personnel and experienced maintenance staff to troubleshoot the network.
Enabling the debugging will generate a large amount of debugging information and decrease the system efficiency. Specially, network system may collapse after all the debugging is enabled by the debugging all command. So it is not suggested to use the debugging all command. It is convenient for the user to disable all the debugging with undo debugging all command.
Related commands: display debugging.
Examples
# Enable IP packet debugging.
<H3C> debugging ip packet
<H3C> display debugging
IP packet debugging is on
The above output shows that the IP packet debugging is enabled.

View
Any view
Parameters
-a ip-address: Specifies the source IP address of an ICMP echo request (ECHO-REQUEST).
-c count: Specifies the number of ICMP echo requests sent, in the range 1 to 4294967295. The default value is 5.
-d: Sets socket to DEBUGGING mode. The default is non-DEBUGGING mode.

interface-type: Interface type.
interface-num: Interface number.
interface-name: Interface name.
-i: Specifies the ICMP echo request sending interface.
-n: Specifies that the host argument is used as the IP address, without domain name resolution performed. By default, host is taken as the IP address, and if host is not an IP address, domain name resolution will be performed.
-p: Specifies the padded bytes in an ICMP echo request, in hexadecimal format. For example, if pattern is configured as ff, then the packets will be padded with ff. By default, the padded bytes start from 0x01 up to 0x09, where another round starts again if necessary.
-q: Presence of this keyword indicates that only statistics are displayed. By default, all information is displayed.
-r: Records routes. By default, routes are not recorded.
-s packet-size: Specifies length (in bytes) of an ICMP echo request (excluding the IP and ICMP header). The default value is 56.
-t timeout: Specifies the timeout value (in milliseconds) of an ICMP echo reply (ECHO-REPLY). It defaults to 2000 ms.
-tos tos: Specifies type of service (ToS) of an echo request, in the range 0 to 255. The default value is 0.
-v: Displays non ICMP echo replies received. By default, the system does not display non ICMP echo replies.
-vpn-instance vpn-instance-name: Specifies the name of a VPN instance.
host: IP address or domain name of the destination host.
ip: Specifies that IP ICMP packets are used.
Description
Use the ping command to check host reachability and network connectivity in an IP or IPX network.
The ping command involves the following steps in its execution:
1) The source device sends an ICMP echo request to the destination host.
2) If the network is functioning properly, the destination host responds by sending an ICMP echo reply to the source device after receiving the ICMP echo request.
You can use the ping command to test network connectivity and connection quality. Output of the ping command falls into the following:
l Information on the destination’s responses towards each ICMP echo request. If the source device does not receive an ICMP echo reply within the timeout time, it displays the prompt information “Request time out.”; otherwise, it displays the number of bytes of the echo reply, the message sequence number, Time to Live (TTL), the response time.
l The statistics during the ping operation, which include number of packets sent, number of echo reply messages received, percentage of messages not received, and the minimum, average, and maximum response time.
If the network transmits data rather slowly, you can set a bigger timeout.
Related commands: tracert.

string: IP address of the destination host or host name of the remote system.
Description
Use the tracert command to trace the gateways involved in delivering a packet from source to destination. This is useful for identification of failed node(s) in the event of network failure.
The tracert command involves the following steps in its execution:
1) The source device sends a packet with a TTL value of 1 to the destination.
2) The first hop responds by sending a TTL-expired ICMP message to the source, with its IP address encapsulated. In this way, the source device can get the address of the first gateway.
3) The source device sends a packet with a TTL value of 2 to the destination.
4) The second hop responds with a TTL-expired ICMP message, which gives the source device the address of the second gateway.
The above process continues until the ultimate destination is reached. In this way, the source device can trace the addresses of all the gateways involved to get to the destination.
After having identified network failure with the ping command, you can use the tracert command to determine the failed node(s).
Output information of the tracert command includes IP addresses of all the gateways the packets traverse from the source to the destination. If a gateway times out, "* * *" will be displayed.
Caution:
At present, the device does not support check of whether a network is reachable using the tracert command and identification of failed node(s) in the event of network failure in an MPLS domain.
