Chapter 1 Command Introduction

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.

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> orthe up arrow key

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

Press <Ctrl+N> orthe down 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.

interface.

server Enables the DHCP Server function on aninterface.

proxy Enables the DHCP Proxy function on aninterface.

Defaults By default all are disable.

Instructions After start the built-in DHCP Relay process, system will resolveDHCP Client’s IP address request on configured user interfaces,dynamically assign IP address for DHCP Client through externalDHCP Server configured on interfaces.

After starting the inside DHCP Server process, system will resolveDHCP Client’s IP address request on configured user interfaces,



assign IP address for DHCP Client dynamically. DHCP Server sup-ports to assign IP address for direct connected DHCP users, alsosupports to assign IP address through DHCP users by DHCP Relayforwarding.

Assign IP address for directly connected user, DHCP Server willassign address by attached IP Pool on access DHCP user interface(use peer default ip pool command to attach). DHCP SERVER willchoose corresponding address pool to assign on global configuredall address pool.

After start the built-in DHCP Proxy process, system will resolveDHCP Client’s IP address request on configured user interfaces, dy-namically assign IP address for DHCP Client through external DHCPServer configured on interfaces. When the client sends relettingrequest and if the long lease time that the DHCP Server assignsto DHCP Proxy is not overtime, DHCP Proxy will response to theclient. That is, DHCP Proxy does not need to send reletting requestto DHCP Server. This decreases the burden of DHCP Server.

This system contains DHCP Server, DHCP Relay and DHCP Proxyfunctions inside, but they can’t operate together. Thus, if the DHCPServer function has been started, it must stop the started DHCPServer function before starting DHCP Relay function.

dhcp-poolPurpose Use this command to bind a policy to a DHCP pool. Remove the

binding relationship with no command.

Command Mode DHCP policy configuration mode

Syntax dhcp-pool < pool_name>

no dhcp-pool

SyntaxDescription < pool_name> It is the name of a DHCP pool.

Instructions The platform version 4.8.02 or later supports this command. Thisis the required configuration of the DHCP function. It is to binda DHCP pool with a policy. The configuration of the DHCP policymust be consistent with the configuration in the network structure.The DHCP pool bound to the policy must match the interface onwhich the policy is bound. If the address pool of another interfaceis bound to the policy by mistake, address allocation will fail.

Example This example describes how to bind a DHCP pool named dpool1.ZXR10(config)#ip dhcp policy policy1 2ZXR10(config-dhcp-policy)#dhcp-pool dpool1ZXR10(config-dhcp-policy)#exit

Related Command show ip dhcp policy

vrrp advertisePurpose Use this command to set the time interval for sending VRRP adver-

tisement on the interface. Restore the default with the no com-mand.


Syntax vrrp <group> advertise [msec]<interval>

no vrrp <group> advertise

SyntaxDescription <group> Virtual router ID, 0 ~ 255.

msec Change the unit of the time from second intominute

<interval> Interval for the master to send VRRPadvertisements. In the unit of second, 1 ~255; in the unit of milliseconds, 100 ~25000.1 second by default

Instructions VRRP enables advertisement interval of less than one second.However, in encapsulating packets, the advertisement time shallbe one second. In this way, the time learned by the other end willstill one second, and the configuration of less than one secondwill not be learned.

Example This example describes how to configure the time interval for send-ing VRRP advertisement on the interface as 2 seconds.ZXR10(config)#interface vlan 1ZXR10(config-if)#vrrp 1 advertise 2

interface and run the CRRP protocol. Clear the setting with the nocommand.


Syntax vrrp <group> ip <ip-address>[secondary]

no vrrp <group>[ip <ip-address>]


<ip-address> IP address in the dotted decimal notation

secondary The other IP address supported by thisvirtual router, that is, the secondary virtual IPaddress. If this parameter is not used, it isthe primary virtual IP address.

Instructions � Requirement to set VRRP virtual addresses:



� Do not set to the same virtual address as the current groupon the interface.

� Do not set to the same virtual address as the other groupon the interface.

� Do not set to the same virtual address as any group on theother interfaces.

� Do to set to one address that will be in the same subnet asthat of the other interfaces.

� Do not repeat the address of the other interfaces.

� The no command will delete all the settings of this group if noIP address is specified.

� The primary virtual IP address of a group is unique. If theprimary virtual IP address is configured several times. Thelast configuration will overwrite the previous configurations.

Example This example describes how to run the VRRP protocol on the in-terface and configure the primary virtual IP address of the VRRPvirtual router (ID 1) as 10.1.1.1.ZXR10(config)#interface vlan 1ZXR10(config-if)#vrrp 1 ip 10.1.1.1
