subaddress: Supports subaddress allocation. That is, the DHCP server and clients are on the same 

network segment, and the server allocates IP addresses from the address pool containing the network 

segment of the first subaddress if several subaddresses exist. 

Use the dhcp select  server  global-pool command to enable the DHCP server on specified 

interface(s). After the interface receives a DHCP request, the DHCP server will allocate an IP address 

from the address pool. 

Use the undo dhcp select  server  global-pool subaddress command to cancel the support for 

subaddress allocation.
