Configuration procedure
1) Add all the ports on Switch B into VLAN 10, and configure the IP address of VLAN-interface 10 on
Switch A (the configuration procedure is omitted).
2) Configure Switch A as a DHCP server
# Configure DHCP address pool 0.
<SwitchA> system-view
[SwitchA] dhcp enable
[SwitchA] dhcp server ip-pool 0
[SwitchA-dhcp-pool-0] network 10.1.1.0 mask 255.255.255.0
[SwitchA-dhcp-pool-0] display interface vlan-interface 10
Vlan-interface10 current state: UP
Line protocol current state: UP
Description: Vlan-interface10 Interface
The Maximum Transmit Unit is 1500
Internet Address is 10.1.1.1/24 Primary
IP Packet Frame Type: PKTFMT_ETHNT_2,
IPv6 Packet Frame Type: PKTFMT_ETHNT_2,
Last 300 seconds input:
Last 300 seconds output:
0 packets input, 0 bytes, 0 drops
0 packets output, 0 bytes, 0 drops
From the above information, you can see that the MAC address of VLAN-interface 10 is
000f-e249-8050.
3) Configure Host A and Host B as DHCP clients (the configuration procedure is omitted).
4) Configure Switch B
# Enable DHCP snooping.
<SwitchB> system-view
[SwitchB] dhcp-snooping
[SwitchB] interface gigabitethernet 1/0/1
[SwitchB-GigabitEthernet1/0/1] dhcp-snooping trust
[SwitchB-GigabitEthernet1/0/1] quit
# Enable ARP detection for VLAN 10. Configure the upstream port as a trusted port and the
downstream ports as untrusted ports (a port is an untrusted port by default).
[SwitchB] vlan 10
[SwitchB-vlan10] arp detection enable
[SwitchB-vlan10] interface gigabitethernet 1/0/1

[SwitchB-GigabitEthernet1/0/1] quit
# Configure a static IP Source Guard binding entry on GigabitEthernet 1/0/2.
