OpenWrt's wifi-scripts validator rejects any macfilter value other than "allow"/"deny" outright — confirmed on real hardware, setting macfilter='disable' puts netifd in a permanent restart crash loop with the radio stuck down. The only way to disable filtering is to delete the option entirely. Also guards against pushing an empty whitelist (macfilter='allow' with zero MACs blocks every client outright) by treating it as equivalent to "off".
napalm-openwrt
NAPALM community driver for OpenWrt routers and access-points.
Communicates over SSH using Netmiko (linux device type).
Requires OpenWrt 19.07 or newer.

Installation
From source:
git clone https://github.com/napalm-automation-community/napalm-openwrt
cd napalm-openwrt
pip install -e .
Quick start
from napalm import get_network_driver
driver = get_network_driver("openwrt")
device = driver("192.168.1.1", "root", "")
device.open()
facts = device.get_facts()
print(facts)
interfaces = device.get_interfaces()
print(interfaces)
device.close()
Supported NAPALM getters
| Getter | Supported | Notes |
|---|---|---|
get_facts |
✅ | Uses /etc/openwrt_release, /tmp/sysinfo/model, /proc/uptime |
get_interfaces |
✅ | Uses ip link show |
get_interfaces_ip |
✅ | Uses ip addr show |
get_interfaces_counters |
✅ | Uses /proc/net/dev |
get_arp_table |
✅ | Uses ip neigh show |
get_mac_address_table |
✅ | Uses bridge fdb show |
get_config |
✅ | Uses uci export |
get_environment |
✅ | CPU from /proc/stat, memory from /proc/meminfo |
get_lldp_neighbors |
✅ | Requires lldpd package installed on device |
get_lldp_neighbors_detail |
✅ | Requires lldpd package installed on device |
Configuration management
Configuration is managed via UCI (Unified Configuration Interface).
Merge candidate
device.load_merge_candidate(config="""
uci set system.@system[0].hostname='my-router'
uci set network.lan.ipaddr='10.0.0.1'
""")
print(device.compare_config())
device.commit_config()
Replace candidate
with open("full-config.uci") as f:
device.load_replace_candidate(config=f.read())
print(device.compare_config())
device.commit_config()
Rollback
# Reverts to the config state before the last commit_config call
device.rollback()
Development
# Create and activate a virtual environment
python -m venv .venv
source .venv/bin/activate
# Install with dev dependencies
pip install -e ".[dev]"
# Run tests
pytest
# Lint
