IP DHCP BINDING
clear ip dhcp binding
Overview 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.
Examples To clear the specific IP address binding 192.168.1.1, use the command:
awplus# clear ip dhcp binding ip 192.168.1.1
To clear all dynamic DHCP entries, use the command:
awplus# clear ip dhcp binding all
