Service Manual

NOTE: The configuration file maintains normal BMP functionality when a preconfiguration 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 preconfiguration script using the DHCP offer.

• Download and execute scripts before configurations are applied, allowing preconfiguration 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.

Configure BMP

BMP supports two types of Reload modes: BMP mode and Normal mode.

Reload Modes

This section describes the following Reload modes:

• BMP Mode

• Normal Mode

BMP mode is the default boot mode configured for a new system arriving from the Dell factory. This

mode obtains the Dell Networking OS image and configuration file from a network source (DHCP and file

servers).

To boot up the switch with the management port in No Shutdown mode, use Normal mode. If the

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