In the CLI, use the
show dhcp server lease
operational
command to view lease information about the allocated IP addresses.
If you don’t want to wait for expired leases to be released automatically,
you can use the
clear dhcp lease interface
<interface>
expired-only
command
to clear expired leases, making those addresses available in the
pool again. You can use the
clear dhcp lease interface
<interface>
ip
<ip_address>
command
to release a particular IP address. Use the
clear dhcp lease interface
<interface>
mac
<mac_address>
command
to release a particular MAC address.
