DHCP <POOL>
host address
3 Specify the client hardware address.
DHCP <POOL>
hardware-address hardware-address type
• hardware-address: the client MAC address.
• type: the protocol of the hardware platform.
The default protocol is Ethernet.
Debugging the DHCP Server
To debug the DHCP server, use the following command.
• Display debug information for DHCP server.
EXEC Privilege mode
debug ip dhcp server [events | packets]
Using DHCP Clear Commands
To clear DHCP binding entries, address conicts, and server counters, use the following commands.
• Clear DHCP binding entries for the entire binding table.
EXEC Privilege mode.
clear ip dhcp binding
• Clear a DHCP binding entry for an individual IP address.
EXEC Privilege mode.
clear ip dhcp binding ip address
Congure the System to be a DHCP Client
A DHCP client is a network device that requests an IP address and conguration parameters from a DHCP server.
Implement the DHCP client functionality as follows:
• The switch can obtain a dynamically assigned IP address from a DHCP server. A start-up conguration is not received. Use bare metal
provisioning (BMP) to receive conguration parameters (Dell EMC Networking OS version and a conguration le). BMP is enabled as
a factory-default setting on a switch.
A switch cannot operate with BMP and as a DHCP client simultaneously. To disable BMP in EXEC mode, use the stop bmp command.
After BMP stops, the switch acts as a DHCP client.
• Acquire a dynamic IP address from a DHCP client is for a limited period or until the client releases the address.
• A DHCP server manages and assigns IP addresses to clients from an address pool stored on the server. For more information, refer to
Conguring the Server for Automatic Address Allocation.
• Dynamically assigned IP addresses are supported on Ethernet, VLAN, and port-channel interfaces.
• The public out-of-band management interface and default VLAN 1 are congured by default as a DHCP client to acquire a dynamic IP
address from a DHCP server.
• By default, the switch is congured to operate in BMP mode as a DHCP client that sends DHCP requests to a DHCP server to retrieve
conguration information (IP address, boot-image lename, and conguration le). All ports and management interfaces are brought up
