Setup Guide

in Layer 3 mode and pre-congured with no shutdown and no ip address. For this reason, you cannot enter conguration
commands to set up the switch. To interrupt a BMP process, prevent a loop from occurring, and apply the Dell EMC Networking OS
image and startup conguration stored in the local ash, enter the stop bmp command from the console. To recongure the switch
so that it boots up in normal mode using the Dell EMC Networking OS image and startup conguration le in local ash, enter the
reload-type normal-reload command and save it to the startup conguration:
DellEMC# reload-type normal-reload
DellEMC# write memory
DellEMC# reload
• To re-enable BMP mode for the next reload, enter the reload-type jump-start command.
• If the management port is associated with any non-default VRF, then the ip address dhcp command does not work.
Conguring the DHCP Client System
This section describes how to congure and view an interface as a DHCP client to receive an IP address.
Dell EMC Networking OS Behavior: The ip address dhcp command enables DHCP server-assigned dynamic addresses on an
interface. The setting persists after a switch reboot. To stop DHCP transactions and save the dynamically acquired IP address, use the
shutdown command on the interface. To display the dynamic IP address and show DHCP as the mode of IP address assignment, use the
show interface type slot/port[/subport] command. To uncongure the IP address, use the no shutdown command
when the lease timer for the dynamic IP address is expired. The interface acquires a new dynamic IP address from the DHCP server.
To congure a secondary (backup) IP address on an interface, use the ip address command at the INTERFACE conguration level.
Use the no ip address dhcp command to:
• Release the IP address dynamically acquired from a DHCP server from the interface.
• Disable the DHCP client on the interface so it cannot acquire a dynamic IP address from a DHCP server.
• Stop DHCP packet transactions on the interface.
When you enter the release dhcp command, the IP address dynamically acquired from a DHCP server is released from an interface.
The ability to acquire a new DHCP server-assigned address remains in the running conguration for the interface. To acquire a new IP
address, use the renew DHCP command in EXEC Privilege mode or the ip address dhcp command in INTERFACE Conguration
mode.
To manually congure a static IP address on an interface, use the ip address command. A prompt displays to release an existing
dynamically acquired IP address. If you conrm, the ability to receive a DHCP server-assigned IP address is removed.
To enable acquiring a dynamic IP address from a DHCP server on an interface congured with a static IP address, use the ip address
dhcp
command. A prompt displays to conrm the IP address reconguration. If you conrm, the statically congured IP address is
released. An error message displays if you enter the release dhcp or renew dhcp commands.
To renew the lease time of the dynamically acquired IP, use the renew dhcp command on an interface already congured with a dynamic
IP address.
NOTE
: To verify the currently congured dynamic IP address on an interface, use the show ip dhcp lease command. The
show running-configuration command output only displays ip address dhcp. The currently assigned dynamic IP address
does not display.
To congure and view an interface as a DHCP client to receive an IP address, use the following commands.
1 Enter INTERFACE Conguration mode on an Ethernet interface.
CONFIGURATION mode
interface type slot/port[/subport]
2 Acquire the IP address for an Ethernet interface from a DHCP network server.
INTERFACE mode
Dynamic Host
