ip default-gateway
309
If the device is configured to obtain its IP address from a DHCP server, it
sends a DHCPDISCOVER message to provide information about itself to
the DHCP server on the network.
If the
ip address dhcp
command is used with or without the optional
keyword, the DHCP option 12 field (host name option) is included in the
DISCOVER message. By default, the specified DHCP host name is the
globally configured host name of the device. However,
the ip address
dhcp hostname
host-name command can be used to place a different
host name in the DHCP option 12 field.
The n
o ip address dhcp
command deconfigures any IP address that was
acquired, and sends a DHCPRELEASE message.
Example
The following example acquires an IP address for Ethernet port g16 from
DHCP.
