BMP Commands and Examples
You can congure BMP on supported switches using a series of commands.
To enable BMP mode on your switches, and to apply congurations or run scripts using the BMP commands, see 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 In BMP mode, the default status of the external interface is set to no shutdown and the internal server facing port is set to
shutdown.
3 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.
4 The IP address, boot image lename, and conguration lename are reserved for the system and provides the DHCP reply (the one-
le read method). The system receives its IP address, subnet mask, DHCP server IP, TFTP server address, DNS server IP, bootle
name, and conguration lename from the DHCP server.
5 If a DHCP oer has neither an image path nor a conguration le path, it is an invalid BMP DHCP oer and is ignored. The rst DHCP
oers the following to choose from:
• IP address
• Dell Networking OS image
• Conguration le or pre–conguration script
• IP address and Dell Networking OS image OR IP address and conguration le or pre–conguration script
6 DHCP OFFER is selected. All other ports except the port on which the oer 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.
7 The system sends a message to the server to retrieve the named conguration le or pre–conguration script and/or boot le from
the base directory of the server.
a If you use the optional bootfile-name command, the lename can be 256 bytes. If you specify the lename eld in the
DHCP oer, the lename can be 128 bytes. The name can be a fully qualied URL or a lename only.
b When a Dell Networking OS build image is found, the system compares that build image to the version currently loaded on the
chassis.
• If there is a mismatch between the build images, the system upgrades to the downloaded version and reloads.
