5.2.12.1 Confirmation after setting of configuration definition
(a) Confirmation of IP address acquisition
IP addresses can be acquired if a DHCP server exists in the same network as the
interface of the router specified using a configuration definition command
(dhcp-client) after a DHCP client function is set. Execute a show dhcp lease
command and confirm whether IP addresses can be acquired. Also confirm
whether IP addresses can be acquired when an option is specified using a
configuration definition command (dhcp-client) so that a default router address
or DNS server address can be acquired from the DHCP server.
