Usage Guidelines

Usage Scenario

The dhcp select global command applies to DHCP servers. After receiving a DHCP Request message from a DHCP client, a DHCP server assigns an IP address from the local address pool to the client. Run the dhcp select global command to configure the device to assign IP addresses from the global address pool. When no interface address pool is created for the DHCP server, the DHCP server assigns an IP address from the global address pool to an online user.

The device can also assign IP addresses from an interface address pool using the dhcp select interface command in the interface view.

Prerequisites
  • DHCP has been enabled using the dhcp enable command in the system view.

  • Before running the dhcp select global command, you need to run the ip address command to configure the interface IP address.

Precautions

If the DHCP relay and DHCP server functions are simultaneously configured on an interface, only the DHCP server function takes effect.

Example

# Enable VLANIF100 to use the global address pool.
<Huawei> system-view
[Huawei] dhcp enable
[Huawei] interface vlanif 100
[Huawei-Vlanif100] ip address 10.1.1.1 24
[Huawei-Vlanif100] dhcp select global
