Huawei Technologies Proprietary
2-7
When some DHCP clients send DHCP-DISCOVER packets to the DHCP server to
apply for IP addresses, they construct client IDs and add them in the
DHCP-DISCOVER packets. The DHCP server finds the corresponding IP addresses
based on the client IDs and assigns them to the DHCP clients.
Currently, only one IP address in a global DHCP address pool can be statically bound
to a MAC address or a client ID.
