clear ip dhcp binding
This command clears either a specific lease binding or the lease bindings specified by the
command or DHCP server. The command will only take effect on dynamically allocated
bindings, not statically configured bindings.
Syntax clear ip dhcp binding {ip <ip-address>|mac <mac-address>|all|pool
<pool-name>|range <low-ip-address> <high-ip-address> }
Mode User Exec and Privileged Exec
Usage A specific binding may be deleted by ip address or mac address, or several bindings may
be deleted at once using all, pool or range.
Note that if you specify to clear the ip or mac address of what is actually a static DHCP
binding, an error message is displayed. If all, pool or range are specified and one or more
static DHCP bindings exist within those addresses, any dynamic entries within those
addresses are cleared but any static entries are not cleared.
