>

<

vid-list

Parameters

ipaddr

Removes the entry for this client IP address.

interface

Specifies a port list. Removes all entries for the ports specified.
The port list may contain switch ports and static or dynamic link
aggregators (channel groups).

vlan

Removes all entries associated with the specified VLANs.

Mode

Privileged Exec mode

Description

Use this command to remove one or more dynamic entries from the DHCP
snooping binding database. If you do not specify any of the parameters, all
dynamic entries are removed from the database.

Dynamic entries can also be deleted with the NO IP SOURCE BINDING
command. See “IP SOURCE BINDING” on page 664.

For instructions about how to specify ports, see “Port Numbers in
Commands” on page 69.

Caution

If you remove entries from the DHCP snooping binding 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.
