Huawei's global DHCP settings

Lab Topology:

Purpose: to configure DHCP,pc1 and pc2 to automatically assign network parameters

Experimental requirements: two PCs, one layer 2 switch, one router

The steps of the experiment:

1. Ensure that the links between the client and the server are interconnected

SW: create VLAN 10 to put ports into VLAN 10

System-view

[Huawei] sysname sw

[sw] vlan 10

[sw-vlan10] exit

[sw-vlan10] q

[sw] port-group group-member gi0/0/1 gi0/0/2 gi0/0/3

[sw-port-group]

Jan 8 2018 17:35:46-08:00 sw DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.

191.3.1 configurations have been changed. The current change number is 6, the ch

Ange loop count is 0, and the maximum number of records is 4095.

[sw-GigabitEthernet0/0/1] port link-type access

[sw-GigabitEthernet0/0/2] port link-type access

[sw-GigabitEthernet0/0/3] port link-type access

[sw-port-group] port default vlan 10

[sw-GigabitEthernet0/0/1] port default vlan 10 (put the API into the corresponding VLAN)

[sw-GigabitEthernet0/0/2] port default vlan 10

[sw-GigabitEthernet0/0/3] port default vlan 10

[sw-port-group]

[sw]

Gateway: configure a gateway IP address for VLAN 10 on Router

System-view

Enter system view, return user view with Ctrl+Z.

[Huawei] sysname gateway

[gateway] vlan 10 (create VLAN 10)

[Huawei-vlan10] quit

[gateway] interface Vlanif 10

[gateway-Vlanif10] undo shutdown (enable svi API)

Info: Interface Vlanif10 is not shutdown.

[gateway-Vlanif10] ip address 192.168.10.254 255.255.255.0 (set gateway IP address)

[gateway-Vlanif10] quit

[gateway]

2. Configure the DHCP client

Enter PC and select "automatic acquisition", "Click" application

3. Configure DHCP server

# create an IP address pool

Ip pool VLAN-10

Network 192.168.10.0 mask 255.255.255.0

Gateway-list 192.168.10.254

Dns-list 8.8.8.8

Lease day 3

Enable the DHCP service

Dhcp enable

On the port that receives DHCP messages, configure the DHCP selection method-global; interface gi0/0/0dhcp select global / / means that when the DHCP message is received on the port, it goes directly to the DHCP server to select an available IP address from the globally configured IP address pool.

[gateway] ip pool vlan-10 (create IP address pool)

Info: It's successful to create an IP address pool.

[gateway-ip-pool-vlan-10] network 192.168.10.0 mask 255.255.255.0

[gateway-ip-pool-vlan-10] gateway-list 192.168.10.254 (set default gateway)

[gateway-ip-pool-vlan-10] dns-list 8.8.8.8 (set dns default address)

[gateway-ip-pool-vlan-10] lease day 3 (set valid duration)

[gateway-ip-pool-vlan-10] q

[gateway] dhcp enable (enable DHCP)

Info: The operation may take a few seconds. Please wait for a moment.done.

[gateway] interface GigabitEthernet 0/0/0

[gateway-GigabitEthernet0/0/0] dhcp select global

(enable finding available ip addresses in the global configuration)

[gateway-GigabitEthernet0/0/0]

4. Verification and testing

Summary of the experiment:

DHCP configuration ideas:

1. Ensure the interworking of DHCP messages between DHCP client and server

two。 Configure the DHCP client

Configure PC to obtain IP address automatically

3. Configure the DHCP server

Remove IP addresses / segments that cannot be automatically assigned

Create an IP address pool

Available IP address space

Default gateway

DNS server

4. Enable the DHCP service

Verify, test, save
