Usage
• Enabling this feature will send ARP probes to the client at regular intervals. This interval is determined by
setting arp-age timeout. By default arp-age timeout is 20 minutes however the default timeout can be
changed by using the command ip arp-age <timeout value in minutes>.
◦ The periodic ARP probe aids in detecting any change of IP addresses on end clients.
◦ The periodic probe aids silent clients to stay connected to the switch. Silent clients do not send any traffic to
the switch after authentication which causes de-authenticated after a logoff period of 5 minutes (default
value) due to inactivity. The periodic ARP probe triggers the end client to send response packets and aids
