13 Ping, tracert, and system debugging commands debugging Use debugging to enable debugging for a module. Use undo debugging to disable debugging for a module or for all modules. debugging module-name [ option ] undo debugging { all module-name [ option ] } Debugging is disabled for all modules. User view module-name: Specifies a module by its name, such as arp or device. To display the current module name, use the debugging? command. option: Specifies the debugging option for a module. The option number and content differ for different modules. To display the supported options, use the debugging module-name? command. all: Disables debugging for all modules. Output of debugging commands is memory intensive. 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. The information center then sends the messages to appropriate destinations based on the log output configuration. For more information about the information center, see Network Management and Monitoring Configuration Guide. # Enable debugging for the device management module. <Sysname> debugging dev Related commands display debugging display debugging Use display debugging to display the enabled debugging features. display debugging [ module-name ] 1

14 Any view network-operator module-name: Specifies a module by its name. To display the current module name, use the display debugging? command. # Display all enabled debugging features. <Sysname> display debugging DEV debugging switch is on Related commands ping debugging Use ping to test the reachability of the destination IP address and display ping statistics. ping [ ip ] [ -a source-ip -c count -f -h ttl -i interface-type interface-number -m interval -n -p pad -q -r -s packet-size -t timeout -tos tos -v ] * host Any view 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 this option is not specified, 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 , and the default is 5. -f: Sets the "do-not-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 i interface-type interface-number: Specifies the source interface for ICMP echo requests. If you do not specify this option, the system uses the primary IP address of the matching route's egress interface as the source interface for 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

15 -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 0x f 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 0x 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 (in bytes) of ICMP echo requests (excluding the IP packet header and the ICMP packet header). The value range is 20 to 8100, and the default is 56. -t timeout: Specifies the timeout time (in milliseconds) of an ICMP echo reply. The value range is 0 to 65535, and the default is 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. -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 (.). To use the name of the destination host to perform the ping operation, you must first configure the DNS on the device. Otherwise, the ping operation will fail. To abort the ping operation during the execution of the command, press Ctrl+C. # Test whether the device with an IP address of is reachable. <Sysname> ping Ping ( ): 56 data bytes, press CTRL_C to break 56 bytes from : icmp_seq=0 ttl=254 time=2.137 ms 56 bytes from : icmp_seq=1 ttl=254 time=2.051 ms 56 bytes from : icmp_seq=2 ttl=254 time=1.996 ms 56 bytes from : icmp_seq=3 ttl=254 time=1.963 ms 56 bytes from : icmp_seq=4 ttl=254 time=1.991 ms --- Ping statistics for packet(s) transmitted, 5 packet(s) received, 0.0% packet loss round-trip min/avg/max/std-dev = 1.963/2.028/2.137/0.062 ms # Test whether the device with an IP address of is reachable.

17 ping ipv6 Use ping ipv6 to test the reachability of the destination IPv6 address and display IPv6 ping statistics. ping ipv6 [ -a source-ipv6 -c count -i interface-type interface-number -m interval -q -s packet-size -t timeout -tc traffic-class -v ] * host Any view -a source-ipv6: Specifies an IPv6 address of the device as the source IP address of ICMP echo requests. If this option is not specified, the source IPv6 address of ICMP echo requests is the IPv6 address of the outbound interface. (The address selection rule is defined by RFC 3484.) -c count: Specifies the number of ICMPv6 echo requests that are sent to the destination. The value range is 1 to , and the default is 5. -i interface-type interface-number: Specifies the source interface for ICMPv6 echo requests. This option must be specified when the destination address is a multicast address or a link local address. If you do not specify this option, the system uses the primary IP address of the matching route's egress interface as the source interface for ICMPv6 echo requests. -m interval: Specifies the interval (in milliseconds) to send an ICMPv6 echo reply. The value range is 1 to 65535, and the default is q: Displays only the summary statistics. If you do not specify this keyword, the system displays all the ping statistics. -s packet-size: Specifies the length (in bytes) of ICMPv6 echo requests (excluding the IPv6 packet header and the ICMPv6 packet header). The value range is 20 to 8100, and the default is 56. -t timeout: Specifies the timeout time (in milliseconds) of an ICMPv6 echo reply. The value range is 0 to 65535, and the default is tc traffic-class: Specifies the traffic class value in an ICMPv6 packet. The value range is 0 to 255 and the default is 0. -v: Displays detailed information (including the dst field and the idx field) about ICMPv6 echo replies. If this keyword is not specified, the system only displays brief information (not including the dst field and the idx field) about ICMPv6 echo replies. host: Specifies the IPv6 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 (.). To use the name of the destination host to perform the ipv6 ping operation, you must first configure DNS on the device. Otherwise, the ipv6 ping operation fails. To abort the ping ipv6 operation during the execution of the command, press Ctrl+C. # Test whether the IPv6 address (2001::2) is reachable. <Sysname> ping ipv6 2001::2 Ping6(56 data bytes) 2001::1 --> 2001::2, press CTRL_C to break 56 bytes from 2001::2, icmp_seq=0 hlim=64 time= ms 5

22 NQA commands NQA client commands data-fill Use data-fill to configure the payload fill string for probe packets. Use undo data-fill to restore the default. data-fill string undo data-fill The payload fill string is the hexadecimal number ICMP/UDP echo operation view UDP jitter operation view ICMP/TCP/UDP template view string: Specifies a case-sensitive string of 1 to 200 characters. If the payload length is smaller than the string length, only the first part of the string is filled. For example, if you configure the string as abcd and set the payload size to 3 bytes, abc is filled. If the payload length is greater than the string length, the system fills the payload with the string cyclically until the payload is full. For example, if you configure the string as abcd and the payload size as 6 bytes, abcdab is filled. How the string is filled depends on the operation type. For the ICMP echo operation, the string fills the whole payload of an ICMP echo request. For the UDP echo operation, the first five bytes of the payload of a UDP packet are for special purpose. The string fills the remaining part of payload. For the UDP jitter operation, the first 68 bytes of the payload of a UDP packet are for special purpose. The string fills the remaining part of the payload. # Specify abcd as the payload fill string for ICMP echo requests.
