Bare Metal Provisioning (BMP) - Config | 21
BMP Commands and Examples
You can configure BMP on supported switches using a series of commands. To
enable BMP mode on switches, and to apply configuration or run scripts using 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
provided in the DHCP reply (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 file-
name from the DHCP server.
4. If a DHCP offer has neither an image path nor configuration file path, it is considered an invalid
BMP DHCP offer and is ignored. The first DHCP offers the following to choose:
• 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. The 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

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

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 preconfigura-
tion script and/or boot file from the base directory of the server.
a If you use the optional bootfile-name command, the filename can be 256 bytes. If
a filename field is specified in the DHCP offer, the filename can be 128 bytes. The
name can be a fully qualified URL or it can be a filename only.
