Enabling DHCP You need to enable DHCP before performing other DHCP-related configurations,
which takes effect only after DHCP is enabled.
Configuring Global
Address Pool Mode on
Interface(s)
You can configure the global address pool mode on the specified or all interfaces
of a DHCP server. After that, when the DHCP server receives DHCP packets from
DHCP clients through these interfaces, it assigns IP addresses in the global address
pool to the DHCP clients.
