Purpose
Enters global configuration mode.
• Enters interface configuration mode, where slot/port
is the physical Ethernet interface for which you want
to enable the DHCP client feature.
• Enters interface configuration mode and specifies the
management interface as the interface for which you
want to enable the DHCP client feature.
• Enters interface configuration mode, where vlan-id is
the ID of the VLAN for which you want to enable the
DHCP client feature.
You must enter this command before assigning an IPv6
address to the interface in the next step. This command is
not required if you will assign an IPv4 address to the
interface.
Assigns an IPv4 or IPv6 address to the interface.
The no form of this command releases the IP address.
Displays the IPv4 or IPv6 address assigned to the interface
in the running configuration.
Copies the running configuration to the startup
configuration.
Only the {ip | ipv6} address dhcp command is saved. The
assigned IP address is not saved even though it shows in
the running configuration.
