• clear ip dhcp
Configure an Ethernet interface to acquire its IP address from a DHCP network server.
ip address dhcp
INTERFACE
The Ethernet is not configured to operate as a DHCP client and receive a dynamic IP address.
Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module
The ip address dhcp command enables an Ethernet interface to acquire a DHCP server-assigned
dynamic IP address. This setting persists after a switch reboot. If you enter the shutdown command on
the interface, DHCP transactions are stopped and the dynamically-acquired IP address is saved. Use
the show interface type slot/port command to display the dynamic IP address and DHCP as the mode
of IP address assignment. If you later enter the no shutdown command and the lease timer for the
dynamic IP address has expired, the IP address is unconfigured and the interface tries to acquire a new
dynamic address from DHCP server.
You cannot configure a secondary (backup) IP address on an interface using the ip address dhcp
command; you must use the ip address command at the interface configuration level.
To release a DHCP-assigned IP address and remove the interface from being a DHCP client, enter the
no ip address dhcp command. When you enter the no ip address dhcp command:
• The IP address dynamically acquired from a DHCP server is released from the interface.
• The DHCP client is disabled on the interface; it can no longer acquire a dynamic IP address from a
DHCP server.
• DHCP packet transactions on the interface are stopped.
To display the currently configure dynamic IP address and lease time, enter the show ip dhcp lease
command.
