---- More ----
NOTE:The preceding information provides some level-1 keywords that can be used behind display. Additional keywords can be added behind these displayed keywords.
Different device models or versions support different features. The keywords displayed may be different from the preceding information.
This section involves only commonly used display commands. For more display commands, see the Command Reference of the corresponding product version.
9.1.2 Regular Expression in display Commands
Regular Expressions
When you run the display command to check the device configuration and running status information, you can filter out unnecessary information based on the regular expression.
A regular expression is a mode matching tool. You can create a matching mode based on specified rules and then match target objects based on the matching mode. A regular expression consists of 1 to 256 common characters and special characters.
Common characters
Common characters are used to match themselves in a string, including all upper-case and lower-case letters, digits, punctuations, underline, and special symbols. For example, a matches the letter "a" in "abc", 20 matches the digit "20" in "20.1.1.1", and @ matches the symbol "@" in "xxx@xxx.com".
Special characters
Special characters are a set of symbols with special meanings which are provided to flexibly create matching modes. The special characters are also called metacharacters. Table 9-1 describes special characters and their syntax.
Table 9-1 Description of special charactersSpecial Characters
Function
Example
\
Defines an escape character, which is used to mark the next character (common or special) as the common character.
\* matches "*".
^
Matches the starting position of the string.
^10 matches "10.10.10.1" instead of "20.10.10.1".
$
Matches the ending position of the string.
1$ matches "10.10.10.1" instead of "10.10.10.2".
*
Matches the preceding element zero or more times.
10* matches "1", "10", "100", "1000", and so on.
(10)* matches "null", "10", "1010", "101010", and so on.
+
Matches the preceding element one or more times.
10+ matches "10", "100", "1000", and so on.
(10)+ matches "10", "1010", "101010", and so on.
?
Matches the preceding element zero or one time.
NOTE:Huawei data communication devices do not support regular expressions with ?. When regular expressions with ? are entered on Huawei data communication devices, helpful information is provided.
10? matches "1" or "10".
(10)? matches "null" or "10".
.
Matches any single character.
0.0 matches "0x0", "020", and so on.
.oo. matches "book", "look", "tool", and so on.
()
Defines a subexpression, which can be null. Both the expression and the subexpression should be matched.
100(200)+ matches "100200", "100200200", and so on.
x|y
Matches x or y.
100|200 matches "100" or "200".
1(2|3)4 matches "124" or "134", instead of "1234", "14", "1224", and "1334".
[xyz]
Matches any single character in the regular expression.
[123] matches the character 2 in "255".
[^xyz]
Matches any character that is not in the regular expression.
[^123] matches any character except for "1", "2", and "3".
[a-z]
Matches any character within the specified range.
[0-9] matches any character ranging from 0 to 9.
[^a-z]
Matches any character beyond the specified range.
[^0-9] matches all non-numeric characters.
A simple regular expression does not contain any special character. For example, you can create a simple regular expression "hello" to match the character string "hello" only. In practice, multiple common and special characters are used together to match a character string with special features.
Degeneration of special characters
Certain special characters, when placed at certain positions in a regular expression, degenerate to common characters.
The special characters following "\" match special characters themselves.
The special characters "*", "+", and "?" are placed at the starting position of the regular expression. For example, +45 matches "+45" and abc(*def) matches "abc*def".
The special character "^" is placed at any position except for the start of the regular expression. For example, abc^ matches "abc^".
The special character "$" is placed at any position except for the end of the regular expression. For example, 12$2 matches "12$2".
A right parenthesis ")" or right bracket "]" is not paired with a corresponding left parenthesis "(" or bracket "[". For example, abc) matches "abc)" and 0-9] matches "0-9]".
Unless otherwise specified, degeneration rules also apply when the preceding regular expressions are subexpressions within parentheses.
Usage of Regular Expressions
- Specifying a filtering mode in a command: enter the keyword begin, exclude, or include, and a regular expression in the command line to filter command outputs.
- Specifying a filtering mode on a split screen: enter a slash (/), minus (-), or plus (+) symbol, and a regular expression to filter command outputs to be displayed on a split screen. The slash (/), minus (-), and plus (+) symbols have the same functions as the keywords begin, exclude, and include.
Specifying a Filtering Mode in a Command
Three filtering modes are provided for commands that support regular expressions.
| begin regular-expression: displays all the lines beginning with the line that matches the regular expression.
Filter the character strings to be entered until the specified case-sensitive character string is displayed. All the character strings following this specified character string are displayed on the screen.
| exclude regular-expression: displays all the lines that do not match the regular expression.
If the character strings to be entered do not contain the specified case-sensitive character string, they are displayed on the screen. Otherwise, they are filtered.
| include regular-expression: displays all the lines that match the regular expression.
If the character strings to be entered contain the specified case-sensitive character string, they are displayed on the screen. Otherwise, they are filtered.
NOTE:You can specify the filtering mode of output information for some display commands that have large amount of output information.
before before-line-number: displays lines that match filtering rules and the preceding before-line-number lines.
after after-line-number: displays lines that match filtering rules and the subsequent after-line-number lines.
before before-line-number + after after-line-number or after after-line-number + beforebefore-line-number: displays lines that match filtering rules, the preceding before-line-numberlines, and the subsequent after-line-number lines.
Values of before-line-number and after-line-number are a string of 1 to 999 characters.
The following examples describe how to specify a filtering mode in a command.
Example 1: Run the display interface brief command to display all the lines that do not match Ethernet,NULL, or Tunnel.
<HUAWEI> display interface brief | exclude Ethernet|NULL|TunnelPHY: Physical *down: administratively down ^down: standby (l): loopback (s): spoofing (b): BFD down (e): ETHOAM down (dl): DLDP down (d): Dampening Suppressed InUti/OutUti: input utility/output utility Interface PHY Protocol InUti OutUti inErrors outErrors Eth-Trunk1 down down 0% 0% 0 0 Eth-Trunk17 down down 0% 0% 0 0 LoopBack1 up up(s) 0% 0% 0 0 Vlanif1 up down -- -- 0 0 MEth0/0/1 down down 0% 0% 0 0 Vlanif2 down down -- -- 0 0 Vlanif10 down down -- -- 0 0 Vlanif12 down down -- -- 0 0 Vlanif13 down down -- -- 0 0 Vlanif20 up up -- -- 0 0 Vlanif22 down down -- -- 0 0 Vlanif222 down down -- -- 0 0 Vlanif4094 down down -- -- 0 0

9.2 reset Commands
9.2.1 Overview
The reset commands are used to clear statistics on switches, helping you quickly locate faults. The resetcommands include:
- The commands resetting connections
- The commands clearing statistics
This section involves the reset commands clearing statistics.
9.2.2 reset Commands Clearing Packet Statistics
reset counters interface and reset ip statistics are often used to clear packet statistics displayed in the display interface and display ip interface command output.
- The display interface command provides counters to collect statistics on sent and received Layer 2 packets. The reset counters interface command resets these counters.
- The display ip interface command provides counters to collect statistics on sent and received Layer 3 packets. The reset ip statistics command resets these counters.
9.2.3 Using reset Commands
Context
When you use the ping command to test link connectivity, you also need to run the display interface or display ip interface command to check whether packets are correctly sent and received on interfaces and whether a CRC error occurs. Then you can locate the interface where the fault occurs.
The display command output shows packet statistics generated after the device starts or the counter is reset; therefore, the packet statistics may contain unnecessary information that interferes with fault location.
To collect packet statistics accurately, perform the following operations:
Procedure
- Run the reset counters interface or reset ip statistics command to clear existing packet statistics.
- Run the ping command to enable device interfaces to send and receive packets.
- Run the display interface or display ip interface commands to view the statistics.
Example
For example, after you run the display interface gigabitethernet 0/0/1 command, the following statistics are displayed:
Input: 99598 packets, 18626534 bytes
Unicast: 0, Multicast: 74750
Broadcast: 24848, Jumbo: 0
Discard: 0, Pause: 0
Total Error: 0
CRC: 0, Giants: 0
Jabbers: 0, Fragments: 0
Runts: 0, DropEvents: 0
Alignments: 0, Symbols: 0
Ignoreds: 0, Frames: 0
Output: 20233 packets, 10217244 bytes
Unicast: 0, Multicast: 20233
Broadcast: 0, Jumbo: 0
Discard: 0, Pause: 0
Total Error: 0
Collisions: 0, ExcessiveCollisions: 0
Late Collisions: 0, Deferreds: 0
Buffers Purged: 0 If the value of Total Error is not 0, there is an error in packet sending and receiving.
To check when the error occurs, run the reset counters interface gigabitethernet 0/0/1 command to clear existing statistics, use the ping command to send ping packets, and run the display interface gigabitethernet 0/0/1 command to view new statistics. If the Total Error value is still not 0, the error may need to be rectified.
9.3 Ping and Tracert
Introduction to the Ping Command
The Ping command implementation is based on the Internet Control Message Protocol (ICMP). The source end sends an ICMP Echo Request message to the destination end to determine reachability. If the source end receives an ICMP Echo Reply message from the destination end within the specified period, the destination end is reachable. Otherwise, the destination end is unreachable. The source end determines the quality of the link to the reachable destination end based on the number of sent ICMP Echo Request messages and received ICMP Echo Reply messages. It also determines the distance between the source end and destination end according to the round-trip time (RTT) of ping packets.
Ping Command Format
NOTE:S1720&S2700&S5700&S6720 Series Ethernet Switches Command Reference provides detailed description of command parameters and usage. The following only describes some of the commonly used parameters.
ping [ ip ] [ -a source-ip-address | -c count | -f | -s packetsize | -t timeout ] * host
-a: specifies the source IP address for sending Echo Request messages. If no source IP address is specified, the IP address of the outbound interface is used as the source IP address.
-c: specifies the count for sending Echo Request messages. The default value is 5. You can increase the number of outgoing packets to detect the network quality based on the packet loss ratio.
-f: indicates that packets are not fragmented when they are sent. The device discards the packets if the packet size exceeds the MTU.
-s: specifies the length of an Echo Request message without the IP header and ICMP header. The default value is 56 bytes.
-t: specifies the timeout interval of Echo Response messages. You can set a larger timeout interval if the network is unstable. The default value is 2s. If the device receives no Echo Response message, it determines that the destination is unreachable.
host: specifies an IP address or a domain name. If it is a domain name, the device performs DNS resolution and displays the resolved IP address.
NOTE:This section only describes some of the commonly used parameters. For additional details, see ping in section Ping and Tracert of the Network Management and Monitoring volume in the Command Reference of the corresponding version.
The Ping function varies with the operating system of the PC. The Windows operating system is used as an example.
ping [ -n number ] [ -t ] [ -l number ] [ -f ] [ -a ] ip-address
-n: specifies the number of Ping packets. The default value is 5.
-t: indicates that the source sends Echo Request messages to the destination continuously until manual operations are performed. You can press Ctrl + Break to temporarily stop the Ping command and view the statistics, and press Ctrl + C to end the Ping operation.
-l: specifies the number of bytes of data in Ping packets. The value ranges from 0 to 65500.
-f: indicates that packets are not fragmented when they are sent. The device discards the packets if the packet size exceeds the MTU.
-a: indicates that the device resolves an IP address into a host name.
ip-address: specifies the destination IP address to ping.

5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 1/1/2 ms In this example:
The device sends five Ping packets and receives response for all the five packets.
The Ping packets use the default size, 56 bytes.
The TTL value is 255, indicating that the source is directly connected to the destination.
The time is 1 ms, indicating that the device received an Echo Response message 1 ms after it sent an Echo Request message. This parameter can be used to determine whether the network is congested.
The device sends five Ping packets by default. You can set a larger value for -c to accurately detect the network status. The device determines the network status based on the number of Ping packets returned.
Fault Description | Possible Cause |
|---|---|
All packets can reach the destination but require a long time. | The intermediate network is unstable. QoS is deployed on the gateway, which lowers the forwarding speed. |
No packet can reach the destination. | Services on the network are interrupted due to device or cable faults. The firewall on the intermediate network discards ICMP packets. A loop occurs on the network and packets are discarded when the TTL value is reduced to 1. Packets are delayed due to network congestion. |
Some packets cannot reach the destination. | The network is unstable, leading to discarded packets. Load balancing is configured on the intermediate network and some Ping packets are discarded on a path. Packet flooding attacks. |
Introduction to the Tracert Command
The Ping command checks whether the destination host is reachable and the Tracert command tracks the gateways that packets pass through from the source host to the destination host. This helps check network connectivity and locate network faults.
The tracert command implementation is based on the ICMP. As shown in Figure 9-1, the working process of tracert is as follows:
- The source end (SwitchA) sends a UDP packet whose TTL value is 1 and destination UDP port number is larger than 30000 to the destination end (Log host). A UDP port number larger than 30000 is not commonly used by any program.
- Upon receiving the UDP packet, the first-hop host (SwitchB) determines that the destination IP address of the packet is not its local IP address and decreases the TTL value by one. The TTL value is 0, so SwitchB discards the UDP packet, and sends an ICMP Time Exceeded message containing its local IP address 10.1.1.2 to SwitchA. SwitchA obtains the IP address of SwitchB.
- Upon receiving the ICMP Time Exceeded message from SwitchB, SwitchA sends a UDP packet with a TTL value of 2.
- Upon receiving the UDP packet, the second-hop host (SwitchC) returns an ICMP Time Exceeded message containing its local IP address 10.1.2.2 to SwitchA.
- The preceding process is repeated until the destination end determines that the destination IP address of the UDP packet is its local IP address and processes the packet. The destination end searches for the upper-layer protocol that uses the destination port number of the packet. No program uses this UDP port number, so the destination end returns an ICMP Destination Unreachable message containing its local IP address 10.1.3.2.
- Upon receiving the ICMP Destination Unreachable message, the source end determines that the UDP packet has reached the destination end, stops tracert, and generates the path of the UDP packet 10.1.1.2 -> 10.1.2.2 -> 10.1.3.2.
Tracert Command Format
NOTE:S1720&S2700&S5700&S6720 Series Ethernet Switches Command Reference provides detailed description of command parameters and usage. The following only describes some commonly used parameters.
tracert [ -a source-ip-address | -f first-ttl | -m max-ttl | -p port | -q nqueries | -w timeout ] * host
-a: specifies the source address. If this parameter is not specified, the IP address of the outbound interface is used as the source IP address of outgoing packets.
-f: specifies the initial TTL. If the number of hops is smaller than the initial TTL, the source host receives no TTL-expired packet. If a maximum TTL is set, the initial TTL must be smaller than the maximum TTL.
-m: specifies the maximum TTL. The maximum TTL is usually set to the number of hops through which a Tracert packet passes. If an initial TTL is set, the maximum TTL must be larger than the initial TTL. By default, the maximum TTL value is 30.
- -p: specifies the UDP port number of the destination.
- If no UDP port number is specified for the destination, when you run the Tracertcommand, a port with the port number greater than 32768 is randomly chosen for the destination to receive tracert packets.
- Before specifying the UDP port number for the destination, ensure that the port is not in use; otherwise, the Tracert fails.
-q: specifies the number of UDP packets sent each time. You can increase this value to ensure that UDP packets can reach the destination host if network quality is low. By default, 3 UDP packets are sent each time.
-w: sets the timeout interval of Response messages. If a gateway sends a message indicating TTL timeout, " * " is displayed. You are advised to increase the timeout interval when the network is unstable and the transmission speed is low. The default timeout interval is 5000 ms.
host: indicates an IP address or a domain name. If it is a domain name, the device performs DNS resolution and displays the resolved IP address.
The Tracert function varies with the operating system of the PC. The Windows operating system is used as an example for illustration.
tracert [ -d ] [ -h maximum_hops ] [ -j host-list ] [ -w timeout ] host
-d: indicates that the host name is not resolved.
-h: specifies the maximum TTL.
-j: specifies the loose source address routing list.
-w: sets the timeout interval of UDP packets, in milliseconds.
host: specifies the domain name or IP address of the destination host.
Description of the Tracert Command Output
<HUAWEI> tracert 10.135.18.118
