Service Manual

BMP Process Overview

When your system boots up in default BMP mode, the following items are requested.

1 The current (new) Dell Networking OS build image.

2 The configuration file or pre–configuration script (EXPECT, TCL, or Z-shell [ZSH] script).

3 A list of checksums for all these components.

NOTE: If you already installed the SmartScripts package, the pre–configuration scripts can be in Perl,

Python or Ruby.

NOTE: The configuration file maintains normal BMP functionality when a pre–configuration script is not

sent.

BMP Operations

BMP is supported on the user ports and management ports of a switch.

If you enabled virtual link trunking (VLT) on aggregator switches and you are configuring the top-of-rack

(ToR) switch to load BMP, configure the aggregator switches using the lacp ungroup member-

independent vlt command if the DHCP and file servers are reachable using the interface configured as

part of the VLT link aggregation group (LAG).

BMP eases configuration in the following ways:

• Switch access through all ports (management and user ports) with or without the DHCP-based dynamic

IP address configuration of a switch.

• Booting up in Layer 3 mode with interfaces already in No Shutdown mode and basic protocols enabled

to protect the system and network.

• Access to the configuration file or a pre–configuration script using the DHCP offer.

• Download and execute scripts before configurations are applied, allowing pre–configuration checks on

the switch.

IOA Supports BMP

BMP is enabled on the IOA switch. Following are the characteristics of BMP feature in IOA:

• The default reload-type maintains as normal reload-type.

• The management interface initiates the DHCP discover packets.

• IOA switch supports the DHCP image download and upgrade processes.

• The switch also supports the DHCP configuration or script file download procedure.

NOTE: In the IOA switch, the Management Interface is used because the physical interface does not

support Internet Protocol (IP) address configurations.
