Service Manual

NOTE: To apply the startup configuration, cancel the default BMP setup using the stop bmp command from the console. To

disable BMP for the next reload, use the boot-type normal-reload command in reload-type configuration mode.

Normal Mode

When reloaded in Normal mode, the switch boots up with the management port in No Shutdown mode.

If the management IP address is present in the start-up configuration file, it is assigned to the management interface. If the management

IP address is not present in the start-up configuration file, no IP address is assigned. You can connect to the management port with an IP

address on the same network and log in to the system through a telnet or SSH session.

To configure a switch to reload using Normal mode, follow this step.

• Configure a switch to use Normal mode.

RELOAD – TYPE mode

boot-type normal-reload

• 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, 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 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.

5 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 pre–configuration script

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

6 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
