Manual Use GuideThe commands in other volumes are classified by functional mod-ules, and each functional module corresponds to a chapter andthe commands in the chapter are organized in the form of level 2directory and in the order of a–z.

To search a command, do as follows:

1. Find the desired command by referring to ZXR10 Router/Eth-ernet Switch Command Manual — Command Index.

2. Find command details by the volume, chapter/section and pageof the obtained command.

Description of Man-MachineCommandsEach MML command is described by the following items:

� Function

It describes the function implemented by this command.

� Command Mode

It describes the mode in which this command can be executed.

� Format

It describes the complete format of this command, includingthe no format if possible.

� Parameter Description

It describes parameters in this command in the form and pre-scribes the range and default value. If different products have

Confidential and Proprietary Information of ZTE CORPORATION 1


different parameter ranges or default values, an additionalform is used for description.

� Default

The default value is available in the case that this command isnot set. The default parameter value is not described here forvalue selection.

Additional description shall be given if different products havedifferent default values.

� Instructions

First describes the platform version information about thiscommand. For example, “The platform version X.X.XX or latersupports this command” indicates this command is providedfrom the beginning of the platform version X.X.XX. This com-mand is provided from the platform version 2.6 by default.

Second describes the use method and precautions of this com-mand.

� Example

It describes the use of this command in an example.

� Related Commands

Lists the command(s) related to this command.

� History Command

It describes history version information related to this com-mand if a command is changed after version upgrade.

Do not describe the history command if this entry does not exist.

Auxiliary FunctionThe auxiliary function for ZXR10 devices is as follows.

1. In any command mode, enter a question mark (?) after theDOS prompt of the system, a list of available commands in thecommand mode will be displayed. With the context-sensitivehelp function, the keywords and parameter lists of any com-mands can be obtained.

i. In any command mode, enter a question mark "?" after theDOS prompt of the system, and a list of all commands inthe mode and the brief description of the commands willbe displayed.

ii. Input the question mark behind a character or characterstring to view the list of commands or keywords beginningwith this character or character string. Note that there isno space between the character (string) and the questionmark.

iii. Press TAB behind the character string. If the command orkeyword beginning with this character string is unique, itshall be completed with a space at the end. Note that thereis no space between the character string and the TAB.

Chapter 1 Command Introduction

iv. Input a question mark after a command, a keyword or aparameter, the next keyword or parameter to be input willbe listed, and also a brief explanation will be given. Notethat a space must be entered before the question mark.

2. If incorrect command, keyword or parameter is input, the errorisolation is offered with ^ in the user interface after you pressENTER. The ^ is below the first character of the input incorrectcommand, keyword or parameter.

3. ZXR10 router/Ethernet switch allows the command or key-word to be abbreviated into a character or character string thatuniquely identifies this command or keyword. For example, theshow command can be abbreviated to sh or sho.

4. The user interface supports the function of recording inputcommands. A maximum of ten history commands can berecorded. The function is very useful in re-invocation of a longor complicated command or ingress.

To re-invoke a command from the record buffer, conduct oneof the following operations, as shown below.

Command Function

Press CTRL-P or theup arrow key

Re-invokes the latest command in therecord buffer. Repeat these keys toinvoke old commands forwards.

Press CTRL-N or thedown arrow key

Rolls the commands downward. When thelast command line is reached, one moreoperation will roll the commands from thebegging of the buffer cyclically.

In any mode, execute the show history command to list thelatest commands input in this mode.

no ip nat {inside|outside}

Example � This example describes how to configure fei_5/1 interface as aNAT inside interface.ZXR10(config)#interface fei_5/1ZXR10(config-if)#ip nat inside

� This example describes how to configure fei_3/1 interface as aNAT outside interface.ZXR10(config)#interface fei_3/1ZXR10(config-if)#ip nat outside

distribute ip poolPurpose Use this command to set the working mode of IP POOL to dis-

tributed.


Syntax distribute ip pool

no distribute ip pool

Instructions The platform version 4.08.22 and upgrade versions of distributeddevices support this command.

After enabling this command, the address disposal(apply/release)is executed on local linecard, no longer on main control RP. Theeffeciency is improved greatly. But all the disposal is on the inde-pendent linecard, so this mode can not be used in some occasions.

� For example, all layer-3 interfaces across boards(such asSupVLAN interface) are bound to ip pools with the same name.Then users from different linecards will be disributed with thesame ip address.

� Binding layer-3 interfaces across boards to one ippool alsoleads to the same ip address for different users.

This command is applied to simple networking.

2: Packet is too large. The length of packet tobe sent by the router exceeds the MaximumTransmission Unit (MTU) of the link betweenthe router and destination address.

3: timeout. Hop limit is reached duringtransmission or fragment & reassembly timesout.

4: Parameter error. The router attempts tosend a packet with illegal parameter.

128: response request

129: answer

133: router request. The host sends themessage to request the router on a link tosend a route announcement message

134: route announcement

135: neighbor request message. The nodesends this message to obtain the link layeraddress of other nodes on the same link.
