undo debugging { all | module-name debugging-option }

View

User view

Parameters

all: Enables or disables all debugging.

timeout interval: Sets the timeout time for all debugging, in the range of 1 to 1,440 (in minutes). After the setting, all debugging is valid in the specified period which starts from the time when the debugging is enabled. After the period, all debugging will be disabled.

module-name: Module name.

debugging-option: Debugging option.

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.

Ethernet switches provide various debugging functions for technical support specialists and senior maintenance personnel to do network fault diagnostics.

Enabling debugging will generate a great deal of debugging information and thus will affect the efficiency of the system, especially after enabling all debugging through the debugging all command, the system may collapse. Therefore, it is recommended not to use the debugging all command. The undo debugging all command brings great convenience for you to disable all debugging at a time instead of disabling them one by one.

Related commands: display debugging.

Examples

# Enable IP packet debugging.

Description

Use the display diagnostic-information command to display operation information about all or specified functional modules.

When the system goes wrong, you need to collect much information to locate the fault. However, each module has its corresponding display command, which make it difficult for you to collect all the information needed at a time. In this case, you can use display diagnostic-information command to collect the operation information about all or specified module. For displaying all information at a time costs a long time and is not convenient to view, this command provides two modes for you to collect the information

l Output information to the Console.

l Output information to a file.

You can choose one according to the prompt of the system.

Syntax

ping ipx ipx-address [ -c count | -s packetsize | -t timeout ]*

ping clns nsap-address

View

Any view

Parameters

-a ip-address: Sets the source IP address to send the ICMP ECHO-REQUEST packets.

-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: Sets the socket to DEBUGGING mode. By default, it is non-DEBUGGING mode.

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

-h ttl: Sets the TTL (time to live) value of the echo request packets in the range of 1 to 255. By default, the TTL value is 255.

-i: Selects the specified interface to send the ICMP packets.

interface-type: Interface type.

interface-number: Interface number.

-n: Specifies to regard the host-ip argument as an IP address without performing domain name resolution. By default, the host-ip 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 only ff. 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 and not to display the details. By default, all the information including the details and statistics will be displayed.

-r: Specifies to record the routes. By default, the system does not record any route.

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

-t timeout: Sets the timeout time (in ms) waiting for an ECHO-RESPONSE packet after an ECHO-REQUEST packet is sent. The timeout argument ranges defaults to 2,000 ms.

-tos tos: Sets the ToS value of the echo request packets in the range of 0 to 255. By default, this value is 0.

-v: Specifies to display other ICMP packets received (that is, non-ECHO-RESPONSE packets). By default, except for the ECHO-RESPONSE packets, other ICMP packets are not displayed.

ip: Chooses IP ICMP packet.

host-ip: Domain name or IP address of the destination host, 1 to 30 characters long.

ipx: Chooses IPX packet.

ipx-address: IPX address of the destination host.

clns: Chooses CLNS ECHO packets.

nsap-address: NSAP address of the destination host.

Description

Use the ping command to check the connectivity of IP network or IPX network, and the reachability of a host.

The process of executing of the ping command in the IP network: 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. If no response packet is received within the timeout time, including the number of bytes, packet sequence number, TTL and response time of the response packet. 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 waiting for response packet if the network transmission is slow.

Related commands: tracert.

View

Any view

Parameters

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

-f first-TTL: Sets the initial TTL of the packets to be sent, so that this command displays the addresses of only 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 three, 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: Sets 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 displays the addresses of only those gateways from the source destination 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 count. The max-TTL argument ranges from 1 to 255 and defaults to 30.

-p port: Sets 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: Sets the number of packets to be sent every time. The num-packet argument ranges from 0 to 65,535 and defaults to 3.

-w timeout: Sets 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).

host: IP address of the destination host or the host name of the remote system, 1 to 30 characters long.

clns: Connectionless network service, a suit of protocols in OSI system, including CLNP, ISIS and ESIS.

-m max-TTL: Sets a maximum TTL value. The max-TTL argument ranges from 1 to 255 and defaults to 30.

-n num-packet: Indicates the integral number of the sent test packets. The num-packet argument ranges from 0 to 65535 and defaults to 3.

-t timeout: Sets the timeout time of the tracert command. The timeout argument, in seconds, ranges from 0 to 65535 and defaults to 5.

-v: Explains the error if the response packet error occurs. If no error occurs, after you execute the command, the result is the same as the command is executed without -v.

nsap-address: NSAP address of the destination host.

Description

Use the tracert command to trace the gateways the test packets passes through during its journey from the source to the destination. This command is mainly used to check the network connectivity. It can help you locate the trouble spot of the network.

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 in trouble by using the ping command, you can use the tracert command to find where the trouble is in the network.

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

Examples

# Trace the gateways the packets pass through during its journey to the destination with IP address 18.26.0.115.

View

Ethernet port view

Parameters

all: Specifies to detect all error packets on current interface.

none: Specifies not to detect error packets on current interface.

runt: Specifies to detect error packets that are of runt type on current interface. Error packets that are of runt type refer to frames whose data segment is less than 64 bytes without CRC errors.

Description

Use the qe monitor errpkt command to configure error packets detection function on current interface.

A switch does not detect error packets on current interface by default.

If the switch receives a great number of error packets, it will not be able to send/receive packets properly. With error packets monitoring enabled, the switch collects information about received error packets regularly. If error packets are detected, it takes protection measures to ensure that its interfaces send/receive packets properly.

Examples
