Cisco IOS

This is a presence detection scanner for Cisco IOS devices.

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
