from nornir import InitNornir
from nornir_nokia.tasks import nokia_yang_config, nokia_commit

nr = InitNornir(config_file="config.yaml")

# Set configuration via YANG
result = nr.run(
    task=nokia_yang_config,
    path='/nokia-conf:configure/system/name',
    value='my-router',
    commit=False,
)

# Compare candidate vs baseline
result = nr.run(task=nokia_commit, action="compare", output_format="md-cli")

# Commit with confirmation timer
result = nr.run(task=nokia_commit, action="commit", timer=60)

# Confirm commit (accept)
result = nr.run(task=nokia_commit, action="commit")

# Rollback (cancel confirmed commit)
result = nr.run(task=nokia_commit, action="rollback")

CLI Configuration

from nornir_nokia.tasks import nokia_cli_config, nokia_get

# Configure via MD-CLI
result = nr.run(
    task=nokia_cli_config,
    commands=[

        '/configure router interface "demo1" ipv4 primary address 192.168.1.1 prefix-length 24',
    ],
  mode="commit",
  comment="deploy via nornir",
)

# Compare candidate changes without committing
result = nr.run(
  task=nokia_cli_config,
  config='''
  /configure system location "nornir-compare"
  ''',
  mode="compare",
)

# Confirmed commit with timer
result = nr.run(
  task=nokia_cli_config,
  commands=['/configure system contact "nornir-confirmed"'],
  mode="commit",
  timer=120,
)

# Get operational data via CLI
