16 | Bare Metal Provisioning (BMP) - Config
www.dell.com | support.dell.com
Prerequisites
Before you use BMP to auto-configure a supported Dell Networking switch, configure
the following:
• External DHCP server (required) — a network device offering configuration
parameters.
• File server (required) — a network device for storing and servicing files.
• Domain name server (DNS) (optional) — a server that associates domain names
in the network with IP addresses.
• Relay agent (optional) — an intermediary network device that passes messages
between the DHCP clients and the DHCP server when the server is not on the
same subnet. It can also provide IP addresses for multiple subnets.
For more information, refer to Domain Name Server Settings and File Server Settings.
Standard Upgrades with BMP
The standard upgrades performed with BMP provides a fallback mechanism that
allows the switches to return to their previous state.
Switches normally have two partitions to store images. You can select which partition
the boot up. BMP always downloads and saves the image in the inactive partition.
When BMP reloads, it automatically activates this partition so the switch boots up
with the newly downloaded image.
The downloaded configuration is copied to the running configuration and then applied
to the switch.
Verify the operation and performance of the new image and the configuration on the
switch before committing the changes. After the changes are deemed correct, commit
them by performing the following steps:
1. Disable BMP using the reload-type normal-reload command.
2. Make the active partition permanent using the boot system command.
3. If you did not enable auto-save, manually override the startup configuration file
using the write memory command.
You can revert to the previous state by not committing the changes, disabling BMP,
activating the previous partition, and reloading the switch.
Note: The downloaded configuration does not override the startup configuration.
Note: If you enable auto-save, the switch automatically overrides the startup
configuration.
