This is a presence detection scanner for [Cisco](http://www.cisco.com) IOS devices.
<p class='note warning'>
This device tracker needs SSH to be enabled on the router.
</p>
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:
```bash
# 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
```
<p class='note warning'>
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](https://supportforums.cisco.com/discussion/10169296/arp-timeout) to learn more.
</p>
To use this device tracker in your installation, add the following to your `configuration.yaml` file:
```yaml
# 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:

required: true
type: string
password:
