Chapter 6 Interfaces
6.2.2 DHCP Setting Commands
This table lists DHCP setting commands. DHCP is based on DHCP pools. Create a DHCP
pool if you want to assign a static IP address to a MAC address or if you want to specify the
starting IP address and pool size of a range of IP addresses that can be assigned to DHCP
clients. There are different commands for each configuration. Afterwards, in either case, you
have to bind the DHCP pool to the interface.
