DHCP Configuration
DHCP
enables a host on the network to obtain an
address that ensures its proper
communication and the relevant configuration information from a DHCP server.
IPv6 DHCP
Dynamic Host Configuration Protocol for IPv6 (IPv6 DHCP) assigns address parameters
to hosts, which include IPv6 prefix, IPv6 addresses, and other network configuration
parameters.
DHCP Applications
The ZXA10 C300 supports the following DHCP applications:
l
DHCP snooping (including IPv6 DHCP snooping)
The ZXA10 C300 snoop on the DHCP communication process of the specified ONU
in the specified VLAN to record the user IP/MAC relationship of the specified ONU.
Through DHCP snooping, the administrator can implement IP source-guard according
to the IP/MAC binding table.
l
DHCP server
The ZXA10 C300 works as a DHCP server to allocate IP addresses for users.
l
DHCP client (including IPv6 DHCP client)
The ZXA10 C300 works as a DHCP client. It requires an IP address from the specified
DHCP server, so that users can access it through SNMP.

11.1 Configuring DHCP Snooping
After you configure DHCP snooping, the ZXA10 C300 will intercept the DHCP interaction
process on the specified user port, extract the IP address and MAC address, and set up
the DHCP snooping binding table that is the basis of IP source guard.
