Configuration procedure

1. Specify IP addresses for the interfaces on the DHCP server. (Details not shown.)

2. Configure DHCP:

# Enable DHCP.

<RouterB> system-view

[RouterB] dhcp enable

# Enable DHCP server on interface GigabitEthernet 1/0/1.

[RouterB] interface gigabitethernet 1/0/1

[RouterB-GigabitEthernet1/0/1] dhcp select server

[RouterB-GigabitEthernet1/0/1] quit

# Create DHCP user class ss and configure a match rule to match DHCP requests in which the

hardware address is six bytes long and begins with aabb-aabb.

[RouterB] dhcp class ss

[RouterB-dhcp-class-ss] if-match rule 1 hardware-address aabb-aabb-0000 mask

ffff-ffff-0000

[RouterB-dhcp-class-ss] quit

# Create DHCP address pool aa.

[RouterB] dhcp server ip-pool aa

# Specify the subnet for dynamic allocation.

[RouterB-dhcp-pool-aa] network 10.1.1.0 mask 255.255.255.0

# Enable DHCP user class whitelist.

[RouterB-dhcp-pool-aa] verify class

# Add DHCP user class ss to the DHCP user class whitelist.

[RouterB-dhcp-pool-aa] valid class ss

[RouterB-dhcp-pool-aa] quit

Verifying the configuration

# Verify that clients matching the DHCP user class can obtain IP addresses on subnet 10.1.1.0/24

from the DHCP server. (Details not shown.)

# On the DHCP server, display the IP addresses assigned to the clients.

[RouterB] display dhcp server ip-in-use

IP address Client identifier/ Lease expiration Type

Hardware address

10.1.1.2 aabb-aabb-ab01 Jan 14 22:25:03 2015 Auto(C)

Primary and secondary subnets configuration example

Network requirements

As shown in Figure 28, the DHCP server (Router A) assigns IP addresses to DHCP clients in the

LAN.
