I've a DHCP server configured on Cisco 1602. Everything is working fine but after a client leaves the network it's IP address is still visible in "sho ip dhcp binding". Is there a way for DHCP server to remove the unused IPs from the database? For example a ping test once in a while or something like this. Or the only way is to decrease the lease time?
R2#sho run | se dhcp ip dhcp excluded-address 10.0.0.1 10.0.0.154 ip dhcp excluded-address 10.0.0.158 10.0.0.254 ip dhcp pool 1 network 10.0.0.0 255.255.255.0 default-router 10.0.0.1 dns-server 10.0.0.1
