Switch can act as both a DHCP server and a DHCP relay. DHCP server supports not only

dynamic IP address assignment, but also manual IP address binding (i.e. specify a specific IP

address to a specified MAC address or specified device ID over a long period. The differences

and relations between dynamic IP address allocation and manual IP address binding are: 1) IP

address obtained dynamically can be different every time; manually bound IP address will be

the same all the time. 2) The lease period of IP address obtained dynamically is the same as

the lease period of the address pool, and is limited; the lease of manually bound IP address is

theoretically endless. 3) Dynamically allocated address cannot be bound manually. 4) Dynamic

DHCP address pool can inherit the network configuration parameters of the dynamic DHCP

address pool of the related segment.
