Dhcp Configuration - Huawei AR150 series Configuration Manual

Huawei AR150&200 Series Enterprise Routers
Configuration Guide - IP Service
About This Chapter
The Dynamic Host Configuration Protocol (DHCP) dynamically assigns and manages IP
addresses and other configuration parameters from specified address pools to clients, ensuring
reasonable IP address allocation and high usage.
6.1 DHCP Overview
DHCP dynamically assigns IP addresses to users and manages configuration information in a
centralized manner.
6.2 DHCP Features Supported by the AR150/200
This section describes the DHCP features supported by the AR150/200
6.3 Configuring a DHCP Server Based on a Global Address Pool
After a DHCP server based on a global address pool is configured, all online users of the server
can obtain IP addresses from this address pool.
6.4 Configuring a DHCP Server Based on an Interface Address Pool
This section describes how to configure a DHCP server based on an interface address pool. After
the configuration, users that get online from this interface can obtain IP addresses and other
configuration information from the address pool.
6.5 Configuring a DHCP Relay Agent
This section describes how a DHCP client communicates with a DHCP server on another
network segment by using a DHCP relay agent to obtain an IP address and other configurations.
6.6 Configuring a DHCP/BOOTP Client
After a Layer 3 interface of the AR150/200 is specified to function as a DHCP/BOOTP client,
the interface can dynamically obtain an IP address and other configurations from the DHCP
server by using the DHCP/BOOTP protocol.
6.7 Configuring the DHCP Rate Limit Function
You can configure the highest rate at which DHCP packets are sent to the protocol stack in the
system view, VLAN view, or interface view. If different rates are configured in these views, the
rate configured in the interface view takes effect. If this rate does not take effect, the rate
configured in the VLAN view takes effect. If the rate configured in the VLAN view also does
not takes effect, the rate configured in the system view takes effect.
