Concept Guide

• The circuit ID identies the port originating the protocol data unit (PDU) and has the interface details.
• The remote ID is congurable between the switch MAC address, the hostname, or a custom string. To set the remote ID, enable the
relay up-front in reload-type sub mode. If you enable the relay, by default, the remote ID is set to MAC address.
Software Upgrade Using BMP
BMP simplies switch conguration by allowing you to boot images and run congurations that are specied in a DHCP server and also by
automatically downloading les from a le server.
In a network topology with a large number of devices, use BMP to easily administer, upgrade, and maintain your devices.
Congure Auto-Conguration mode using the reload-type bmp command. Reload the switch in Conguration mode using the reload
command.
Apply Congurations Using BMP Scripts
With Dell EMC Networking OS version 9.1(0.0) or later, Open Automation supports a scripting environment when a BMP or Normal reload
occurs. BMP uses pre-conguration scripts, while a Normal reload-type uses an auto-exec script. The BMP post-conguration script runs
on its own, without any BMP or Normal reload-type restrictions.
Pre–conguration Scripts
In BMP, the Dell EMC Networking OS rst accesses the image, then the conguration le or pre–conguration script from the DHCP oer.
Use pre–conguration scripts to:
• verify the integrity of the Dell EMC Networking OS image the DHCP oer downloads
• dynamically decide what types of congurations to apply to your system based on various factors such as network reachability, port
status, or neighbor discovery
• use LLDP to monitor and generate reports for CPU and memory utilization, port trac status, and to perform link and topology
checking
You can provide a pre–conguration script in DHCP option 209 to either congure the switch or download a conguration le. The script
can download a conguration le or apply CLI commands. If present in the downloaded conguration, post-conguration script CLIs
execute.
You can set the system to retry downloading a conguration up to six times or to automatically save the downloaded conguration or script
on the switch.
After the conguration applies, it triggers a post–conguration script to ensure that the congurations and switch functions are correct.
Dene conguration parameters on the DHCP server for each chassis based on the chassis MAC Address or Vendor–Class–Identier in
DHCP oer 60 or a combination of both.
The conguration scripts such as Perl, Python, and Ruby are supported if you pre-installed the SmartScript package on the system.
The system supports pre–conguration scripts in EXPECT, TCLSH, and ZSH.
