hi,
so we have "config reload <url>" to load from a config store or "config
startup" to edit locally...
then reload warm and it moved to the new configuration... we also have "config
overwrite-network <url>"
that operates on the running configuration but imto that one have high
chances to run into bugs... :)
anyway, as you can note, you should take a look at "config ?" maybe others
better fit your needs...
regards,
cs

Hi !

In p4 switch, software configuration is saved in /etc/freertr/rtr-sw.txt

Then you can save multiple files:
/etc/freertr/rtr-test1-sw.txt
/etc/freertr/rtr-test2-sw.txt
/etc/freertr/rtr-test3-sw.txt
/etc/freertr/rtr-test4-sw.txt
/etc/freertr/rtr-test5-sw.txt

And make sure you start freertr with the right
/etc/freertr/rtr-test<x>-sw.txt files

In /opt/freertr/bin/hwdet-main.sh

...
while (true); do
cd /opt/freertr/lib

stty raw < /dev/tty
java -Xmx2048m -jar rtr.jar router $FREERTR_CONFIG/rtr-test<x>
if [ $? -eq 4 ] ; then
sync
reboot -f
fi
stty cooked < /dev/tty
sleep 1
done
…

Note that in that case you also need to have rtr-test<x>-hw.txt

But maybe mc36 have more elegant solutions in his sleeves.


Hope this helps !

Hi all,

I was wondering if is possible to have several control plane configurations
and swap between them depending on the test that you want to execute, for
example, one configuration with 3 VLANs and 1 VRF and the other without VLANs
but with 2 VRF and then test different behaviours in the network just by
loading one of this configurations. Two different control plane
configurations with different purposes.

Thanks for your time,

Best regards,

Carmen Misa
