option: Specifies the debugging option for a module. Available options vary by module. To display the debugging options supported by a module, use the debugging module-name ? command.

all: Specifies all modules.

Usage guidelines

CAUTION:

Output of excessive debugging messages increases the CPU usage and downgrades the system performance. To guarantee system performance, enable debugging only for modules that are in an exceptional condition.

The system sends generated debug messages to the device information center, which then sends the messages to appropriate destinations based on the log output configuration. For more information about the information center, see System Management Configuration Guide.

Parameters

ip: Distinguishes between a destination host name and the ping command keywords if the name of the destination host is i, ip, ipv, ipv6, l, ls, or lsp. For example, you must use the command in the form of ping ip ip instead of ping ip if the destination host name is ip.

-a source-ip: Specifies an IP address of the device as the source IP address of ICMP echo requests. If you do not specify this option, the source IP address of ICMP echo requests is the primary IP address of the outbound interface.

-c count: Specifies the number of ICMP echo requests that are sent to the destination. The value range is 1 to 4294967295, and the default is 5.

-f: Sets the "Don’t Fragment" bit in the IP header.

-h ttl: Specifies the TTL value of ICMP echo requests. The value range is 1 to 255, and the default is 255.

-i interface-type interface-number: Specifies the source interface of ICMP echo requests. If you do not specify this option, the system looks up the routing table or forwarding table for a matching route and uses the output interface of that route as the source interface of ICMP echo requests.

-m interval: Specifies the interval (in milliseconds) to send ICMP echo requests. The value range is 1 to 65535, and the default is 200.

-n: Disables domain name resolution for the host argument. If the host argument represents the host name of the destination, and if this keyword is not specified, the device translates host into an address.

-p pad: Specifies the value of the pad field in an ICMP echo request, in hexadecimal format, 1 to 8 bits. The pad argument is in the range of 0 to ffffffff. If the specified value is less than 8 bits, 0s are added in front of the value to extend it to 8 bits. For example, if pad is configured as 0x2f, then the packets are padded with 0x0000002f to make the total length of the packet meet the requirements of the device. By default, the padded value starts from 0x01 up to 0xff, where another round starts again if necessary, such as 0x010203…feff01….

-q: Displays only the summary statistics. If this keyword is not specified, the system displays all the ping statistics.

-r: Records the addresses of the hops (up to 9) the ICMP echo requests passed. If this keyword is not specified, the addresses of the hops that the ICMP echo requests passed are not recorded.

-s packet-size: Specifies the length (The value range for the packet-size argument varies by device model. in bytes) of ICMP echo requests (excluding the IP packet header and the ICMP packet header). The value range for the packet-size argument is 20 to 8100. The default setting is 56 bytes.

-t timeout: Specifies the timeout time (in milliseconds) of an ICMP echo reply. The value range is 0 to 65535, and the default is 2000. If the source does not receive an ICMP echo reply within the timeout, it considers the ICMP echo reply timed out.

-tos tos: Specifies the ToS value of ICMP echo requests. The value range is 0 to 255, and the default is 0. To use this parameter, enter the complete string -tos. If only part of the parameter is entered, those characters will be treated as the hostname.

-v: Displays non-ICMP echo reply packets. If this keyword is not specified, the system does not display non-ICMP echo reply packets.

host: Specifies the IP address or host name of the destination. The host name is a case-insensitive string of 1 to 253 characters. It can contain letters, digits, and special characters such as hyphen (-), underscore (_), and dot (.).

Usage guidelines

To ping a device identified by its host name, configure the DNS settings on the device first. If the DNS settings are not configured, the ping operation fails.

To abort the ping operation during the execution of the command, press Ctrl+C.

Usage guidelines

After identifying network failure with the ping command, use the tracert command to locate failed nodes.

The output from the tracert command includes IP addresses of all the Layer 3 devices that the packets traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an ICMP error message. The reason might be the destination is unreachable or sending ICMP timeout/destination unreachable packets is disabled.

Before starting a tracert operation, you must enable sending of ICMP destination unreachable messages on the intermediate devices between the source and destination. The tracert operation stops if any of the following ICMP destination unreachable messages is received:

· !N—Network unreachable.

· !H—Destination host unreachable.

· !P—Protocol unreachable. The protocol number is unknown.

· !F—Fragmentation needed. This message indicates that packet fragmentation is needed but the "Don’t Fragment" bit is set on an immediate device.

· !W—Destination host unknown.

· !Q—Network unreachable for ToS.

· !T—Host unreachable for ToS.

· !X—Communication administratively prohibited by filtering policies.

· !V—Host precedence violation.

· !C—Precedence cutoff in effect.

Usage guidelines

After identifying network failure with the ping ipv6 command, you can use the tracert ipv6 command to locate failed nodes.

The output from the tracert ipv6 command includes IPv6 addresses of all the Layer 3 devices that the packets traverse from source to destination. Asterisks (* * *) are displayed if the device cannot reply with an ICMP error message. The reason might be the destination is unreachable or sending ICMP timeout/destination unreachable packets is disabled.

Before starting an IPv6 tracert operation, you must enable sending of ICMPv6 destination unreachable messages on the intermediate devices between the source and destination. The IPv6 tracert operation stops if any of the following ICMPv6 destination unreachable messages is received:

· !N—No route to destination.

· !P—Communication with destination administratively prohibited by filtering policies.

· !A—Address unreachable. The unreachable reason is unknown.

· !S—Beyond scope of source address. This message is displayed if the probe packet has a link-local source address and a non-link-local destination address. Such a packet cannot be delivered to the destination without leaving the scope of the source address.
