The load and mgrload commands

"load" is used for loading modules into netconfd-pro

"mgrload" is used for loading modules into yangcli-pro

When using yangcli-pro, the load command is used to load a YANG module into the server.

After using the load command, the mgrload command may also be needed to load the module into yangcli-pro and keep the current yangcli-pro session synchronized with the server.

For more details see Section 2.15.43 "load" and Section 2.15.50 "mgrload" in the yangcli-pro Manual.
