Usage
Information
For an initial setup, the config-scr-download parameter of the reload-type command is enabled.
After the configuration file is successfully downloaded, the config—scr-download parameter is
automatically disabled. You can enable it again using the reload-type command.
Set the Auto Configuration mode (BMP or Normal reload) using the reload-type command. Next,
enter the reload command to reload the switch in the configured mode.
When a switch reloads in BMP mode, all ports, including the management port, are automatically
configured as Layer 3 physical ports. The switch runs DHCP client on all interfaces. You can reconfigure
the default startup configuration and DHCP timeout values.
If the switch attempts to contact a DHCP server and one is not found, it enters a loop while reloading in
BMP mode. To interrupt the reload and boot up in Normal mode, enter the stop bmp command. The
startup configuration is then loaded from the local flash on the switch.
To toggle between Normal and BMP Auto Configuration modes, use the reload-type command in BMP
3.0. Reload settings for Auto Configuration mode that you configure are stored in memory and retained
for future reboots and BMP software upgrades. To reload the switch in the last configured mode: Normal
reload or BMP mode, you can enter the reload command at any time.
Upgrade any configuration changes that have changed the NVRAM content by performing a reload on the
chassis.
While BMP is on, the Dell Networking OS Command Line Reference Guide prompt changes to “Dell-BMP”.
