DHCP SNOOPING COMMANDS
CLEAR
IP DHCP SNOOPING BINDING
clear ip dhcp snooping binding
Overview Use this command to remove one or more DHCP Snooping dynamic entries from
the DHCP Snooping binding database. If no options are specified, all entries are
removed from the database.
CAUTION: If you remove entries from the database for current clients, they will
lose IP connectivity until they request and receive a new DHCP lease. If you clear
all entries, all clients connected to untrusted ports will lose connectivity.
Syntax
clear ip dhcp snooping binding [<ipaddr>] [interface
<port-list>] [vlan <vid-list>]
Mode Privileged Exec
Usage This command removes dynamic entries from the database. Note that dynamic
entries can also be deleted by using the no variant of the ip dhcp snooping binding
command.
Dynamic entries can individually restored by using the ip dhcp snooping binding
command.
To remove static entries, use the no variant of the ip source binding command.
Example To remove a dynamic lease entry from the DHCP snooping database for a client
with the IP address 192.168.1.2, use the command:
