Overview
This command activates the DHCP client on the interface you are configuring. This
allows the interface to use the DHCP client to obtain its IP configuration details
from a DHCP server on its connected network.
The
client-id
and
hostname
parameters are identifiers that you may want to set in
order to interoperate with your existing DHCP infrastructure. If neither option is
needed, then the DHCP server uses the MAC address field of the request to identify
the host.
The DHCP client supports the following IP configuration options:
•
Option 1 - the subnet mask for your device.
•
Option 3 - a list of default routers.
•
Option 6 - a list of DNS servers. This list appends the DNS servers set on your
device with the
command.
•
Option 15 - a domain name used to resolve host names. This option replaces
the domain name set with the
command. Your device
ignores this domain name if it has a domain list set using the
command.
•
Option 51 - lease expiration time.
The
no
variant of this command stops the interface from obtaining IP
configuration details from a DHCP server.
