Presence Detection
0.33
/components/device_tracker.cisco_ios/

This is a presence detection scanner for Cisco IOS devices.

This device tracker needs SSH to be enabled on the router.

Before using this scanner it is recommended that you lower the ARP cache timeout on your router, as Cisco IOS normally comes with a 4 hour default ARP cache timeout.

For example, the following commands will lower the timeout to 2 minutes on Vlan1:

# 1. use this command to see what Vlan your devices are on
show ip arp

# 2. Go into configure mode
conf t

# 3. Use the Vlan name as you see it from step 1 above
interface Vlan1

# 4. Set a new arp cache timeout
arp timeout 120

# 5. Exit
# Press <ctrl+c> to exit configure mode

# 6. Don't forget to save the new config, so that it will survive a reboot
copy running-config startup-config

If you have a very large number of devices on your VLan (+1000), then you may want to adjust the ARP cache timeout to suit your needs. See this discussion to learn more.

To use this device tracker in your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
device_tracker:
  - platform: cisco_ios
    host: ROUTER_IP_ADDRESS
    username: YOUR_ADMIN_USERNAME
    password: YOUR_ADMIN_PASSWORD

{% configuration %} host: description: The IP address of your router, e.g., 192.168.1.1. required: true type: string username: description: The username of an user with administrative privileges. required: true type: string password: description: The password for your given admin account. required: true type: string {% endconfiguration %}

See the device tracker integration page for instructions how to configure the people to be tracked.
