3.1.1.5 Automate the Python Script Execution
EXOS offers the ability to dynamically execute scripts when a particular event is met using a feature
called UPM.
3.1.1.5.1 UPM
UPM can trigger a script based on time of the day (for example every second, or twice a day at a fixed
time or on a given date), LLDP events, or based on events in the log. This capability combined with
Python scripting allows for very powerful on-switch automation. UPM can pass event-related
parameters to the script; for example, a port number associated to a monitored event, or a MAC
address, etc.
As a basic example, when a port goes up or down in the logs, you can ask UPM to trigger a basic Python
script to create a VLAN and add this port to it, or delete this VLAN and add the port back to the default
VLAN. Obviously, this example is too basic for a real use-case, but it shows the concepts involved. The
Python script would look like this:
import exsh
import sys
if len(sys.argv) < 3:
