Software Upgrade Using BMP
BMP has the capability that simplifies and eases configuration by allowing you to
boot images and run configurations that are specified in a DHCP server, and also
automatically downloading files from a file server and applied by the switch. In a
network topology with a large number of devices, you can employ BMP to
effectively, administer and maintain the devices and upgrade them in a robust,
streamlined way. This method of upgrade and deployment allows judicious
management of large numbers of switches.
You can configure an Auto-Configuration mode using the
reload-type bmp
command. You can reload the switch in configuration mode using the reload
command.
Applying Configurations Using BMP Scripts
With Dell Networking OS version 9.1(0.0) or later, the system supports a scripting
environment when a BMP or Normal reload occurs. BMP uses pre- and post
configuration scripts, while a Normal reload uses an auto-execution script.
Preconfiguration Scripts
In BMP, the Dell Networking OS accesses the image, then the configuration file or
preconfiguration script from the DHCP offer. Use preconfiguration scripts to:
• verify the integrity of the Dell Networking OS image downloaded from the
DHCP offer.
• dynamically decide what types of configurations to apply to your system based
on various factors such as network reachability, port status, neighbor discovery.
• use LLDP to monitor and generate reports periodically for CPU and memory
utilization, port traffic status, and perform link and topology checking.
You can provide a preconfiguration script in DHCP option 209 to either configure the
switch or download a configuration file. The script can download a configuration file
or apply CLI commands. In the downloaded configuration, post configuration script
CLIs are executed if present.
