LS1021ATSN Switch: how does Netconf communicate with SJA1105 Tool ? Is there any documentation about it ?

[darianb_]

I would like to find out how Netconf Commands are read from the SJA1105 Tool.

Hello Darian Biastoch,

XML files generated with sja1105-tool and apply them remotely using NETCONF.

[ubuntu] $ netopeer-cli
netconf> connect --port 830 --login root 192.168.15.11 # board1
netconf> # press Enter for no password
# You may need to run this, in case you are using the candidate
# datastore (here we are not) and it becomes locked.
# See 5.5.5.
# netconf> discard-changes
netconf> edit-config --config board1-{policing|scheduling}.xml running
netconf> get-config running
netconf> copy-config --source running startup
netconf> disconnect
netconf> connect --port 830 --login root 192.168.15.12 # board2
