• DHCP Configuration — Normal mode does not require a separate DHCP server configuration.

• Dell Networking OS Image Retrieval — The Dell Networking OS image is loaded from the local flash

memory.

BMP Commands and Examples

You can configure BMP on supported switches using a series of commands.

To enable BMP mode on your switches, and to apply configurations or run scripts using the BMP

commands, refer the Bare Metal Provisioning CLI section.

System Boot and Set-Up Behavior in BMP Mode

The following steps describe the system boot up process.

1. The system begins the boot up process in BMP mode (the default mode).

2. The system sends DHCP discover on all the interface-up ports.

00:02:14: %STKUNIT0-M:CP %BMP-5-BMP_DISCOVER: DHCP DISCOVER

sent on Ma 0/0.

3. The IP address, boot image filename, and configuration filename are reserved for the system and

provides the DHCP reply (the one-file read method). The system receives its IP address, subnet

mask, DHCP server IP, TFTP server address, DNS server IP, bootfile name, and configuration filename

from the DHCP server.

4. If a DHCP offer has neither an image path nor a configuration file path, it is an invalid BMP DHCP

offer and is ignored. The first DHCP offers the following to choose from:

• IP address

• Dell Networking OS image

• Configuration file or preconfiguration script

• IP address and Dell Networking OS image OR IP address and configuration file or

preconfiguration script

5. DHCP OFFER is selected. All other ports except the port on which the offer was received and

selected are set to Shutdown mode.

00:02:26: %STKUNIT0-M:CP %BMP-5-BMP_DHCP_OFFER: DHCP OFFER

received on Te 0/21 IS SELECTED.

00:02:26: %STKUNIT0-M:CP %BMP-5-BMP_REQUEST: DHCP REQUEST sent

on Te 0/21.

00:02:26: %STKUNIT0-M:CP %BMP-5-BMP_ACK: DHCP ACK received on

Te 0/21.

00:02:26: %STKUNIT0-M:CP %BMP-5-BMP_BOOT_OFFER: DHCP acquired

IP 13.4.4.44 mask 255.255.255.0 server IP 13.4.4.1.

00:02:26: %STKUNIT0-M:CP %BMP-5-BMP_BOOT_OFFER: DHCP tftp IP

NIL sname NIL dns IP NIL router IP NIL.

00:02:27: %STKUNIT0-M:CP %BMP-5-BMP_BOOT_OFFER: DHCP image file

tftp://13.4.4.1/ftos-img-s4810.

00:02:27: %STKUNIT0-M:CP %BMP-5-BMP_BOOT_OFFER: DHCP config

file scp://anvltest:force10@13.4.4.1//tftpboot/basic-l3.

00:02:27: %STKUNIT0-M:CP %BMP-5-BMP_BOOT_OFFER: stacking info

NIL.

6. The system sends a message to the server to retrieve the named configuration file or

preconfiguration script and/or boot file from the base directory of the server.
