We will continue to give you accurate and timely information throughout the crisis, and we will deliver on our mission — to help everyone in the world learn how to do anything — no matter what.
Thank you to our community and to all of our readers who are working to aid others in this time of crisis, and to all of those who are making personal sacrifices for the good of their communities. We will get through this together. Updated: February 22, Tech Tested. DHCP automatically assigns a device-specific IP address to each device on your router's network, which ensures that no two devices will share an IP address and thus encounter connection errors.

If there is nothing, it may because your router is a customized version with which the function is disabled, you could have a check with your carrier. Back to list.Webinar: Introduction and Configuration of DHCP on Huawei Routers

Configuring the DHCP Server
Nothing under DHCP.This topic describes how to configure the WAN interface through the Web page. Exercise caution when you perform this operation. Table describes the parameters related to the WAN in route mode. Indicates whether to enable the WAN connection.
Indicates the encapsulation mode of a WAN interface. Indicates the protocol type of a WAN interface. Indicates the WAN interface mode. Indicates the service type of the WAN interface. It ranges from 1 to Indicates the Indicates the user name that is used for PPPoE dialup. This user name must be the same as that configured on the BRAS. Indicates the password that is used for PPPoE dialup. This password must be the same as that configured on the BRAS. The binding options can be set only after the work mode or wireless SSID is successfully set.
IPv4 Information. Indicates whether to enable the NAT function. Specifies the NAT type. This parameter is configurable only if the NAT function is enabled. Indicates the PPPoE dialup method.
It can be set to AutoManualor On Demand. Sets the option 60 field on the DHCP client. This parameter is used to identify a WAN port uniquely in a customer's network management domain. IPv6 Information.
Indicates the prefix acquisition mode. Indicates the IP acquisition mode.For our configuration example, we will use a single router. On Huawei routers and switches, you can use question mark? This help can be both to complete a command or for the available all commands under that hierarchy. On every router, there are different view modes. On Huawei routers there are four different viw modes.
These are:. User View is the mode that you will enter after login to the router. With this mode, you can check the system configurations. After that to configure a Huawei router, you should enter System View Mode. The other two modes are Interface view and Protocol view.
In these modes, router interfaces and routing protocol configurations are done. There are various shortcuts on Huawei CLI. These shortcuts is useful during router configuration. Some of the important shortcuts are given below:. On all Routers, there is a clock and timezone settings. We can adjust this with various clock commands on Huawei Routers. In some countries, daylight savingm time is used. So, summer and winter times change.
These CLI messages are :.
Header Login message is the message that you will see after the router boots. Header Shell message is the message that you will see after login to the router.
On Routers, there are different user privilege levels. Some of these levels can only view authorization, some of them has configuration authorization and others has different types of authorizations. You can find the levels of Huawei routers below:.
Here, we have set user level to To configure telnet sessions setting on Hauwei routers, firstly we should enter the telnet configuration level. By default 5 telnet sessions can be configured from 0 to 4. Here, we can set also the user privilege level and user password.These functions take effect only after the dhcp enable command is run. After the undo dhcp enable command is run, all DHCP-related configurations of the device are deleted.
By default, STP is enabled. To disable STP, run the undo stp enable command. You can then enable the DHCP server function to operate based on an interface address pool or based on a global address pool. By default, the DHCP server function using the interface address pool is disabled on an interface.
Configure a primary IP address for the interface. The device can select a global address pool based on the primary and secondary IP addresses of an interface only in scenarios where the DHCP server and DHCP clients are on the same network segment.
By default, an interface does not use the global address pool to provide the DHCP server function.
Example for Configuring a DHCP Client
Automatically saving IP address allocation information allows the DHCP server to re-allocate the same configurations such as IP address and lease time to clients in the event that the server unexpectedly restarts. After this function is enabled, the DHCP server stores lease information in lease. New data files overwrite earlier data files. The time displayed in the lease. To view information about the DHCP database, run the display dhcp server database command.
The new data files overwrite the earlier data files. If the detection time is too long, clients may fail to obtain IP addresses. You are advised to set the detection time to less than 8 seconds. Devices from different vendors may use different DHCP implementation mechanisms.
As a result, DHCP becomes unavailable. To solve this problem, you can disable the function of checking abnormal messages to allow the device to properly forward a DHCP message with an incorrect UDP header checksum or an incorrect value in the magic-cookie field.
This enable end devices connected to the same network as the interface. Other interfaces can't use the same segment. The interface pool takes precede over the global pool. All end devices not matter which interface they are connected as long as that interface is added to this global Pool. It's used to associate an interface with the interface address pool.
Por default the default gateway es el mismo servidor DHCP si no se especifica. Used to identify the global address pool. Used to identifies the interface and network segment to which the interface address pool is associated.
Shows the lease IP address for each pool. Configuration of the Relay Agent. DHCP server required global pool to work with relay agents. Configure the Group Name. Interface vlaif You can configure 64 groups in the device and 8 dhcp servers pear group.
One interface can have just one DHCP server group. The maximum number of relay agents cannot exceed 4. The maximum is 5. In the DHCP client. Huawei Enterprise Support Community.

Display ip pool.Users require that all terminals on a network dynamically obtain network parameters such as IP addresses, DNS server IP address, routing information, and gateway information.
The users do not need to manually configure the network parameters including terminal IP addresses. In addition, some mobile terminals for example, mobile phones, tablets, and laptops should support plug-and-play, without modification on network parameters each time.
To meet these requirements, the DHCP server function can be configured on an aggregation-layer user gateway or a core-layer device to assign network parameters such as IP addresses to terminals. The global address pool or an interface address pool can be used. The configuration of an interface address pool is simple, which can be used only when the users and DHCP server belong to the same network segment and the server can only assign network parameters to the users on the interface.
It is applicable to small networks with a limited number of devices and controllable configuration and maintenance workload. After the DHCP server function based on the interface address pool is configured on the user gateway, the hosts and mobile terminals on the interface can automatically obtain network parameters such as IP addresses, without manual configuration and modification.
Compared with an interface address pool, the global address pool can be applied to large networks. The user gateway only needs to be enabled with the DHCP relay function.
