Configuration procedure
1.
Configure dynamic IPv4SG:
# Configure IP addresses for the interfaces. (Details not shown.)
# Enable IPv4SG on VLAN-interface 100 and verify the source IP address and MAC address for
dynamic IPSG.
<Switch> system-view
[Switch] interface vlan-interface 100
[Switch-Vlan-interface100] ip verify source ip-address mac-address
[Switch-Vlan-interface100] quit
2.
Configure the DHCP relay agent:
# Enable the DHCP service.
[Switch] dhcp enable
# Enable recording DHCP relay client entries.
[Switch] dhcp relay client-information record
# Configure VLAN-interface 100 to operate in DHCP relay mode.
[Switch] interface vlan-interface 100
[Switch-Vlan-interface100] dhcp select relay
# Specify the IP address of the DHCP server.
[Switch-Vlan-interface100] dhcp relay server-address 10.1.1.1
[Switch-Vlan-interface100] quit
Verifying the configuration
# Verify that a dynamic IPv4SG binding is generated based on a DHCP relay entry.
[Switch] display ip source binding dhcp-relay
