How Do I Delete Static Binding Entries?

If a binding entry is incorrect or the network rights of a bound host have been changed, you can run the undo user-bind static [ { { ip-address | ipv6-address } { start-ip [ to end-ip ] } &<1-10> | ipv6-prefix prefix/prefix-length } | mac-address mac-address | interface interface-type interface-number | vlan vlan-id [ ce-vlan ce-vlan-id ] ] ^* command to delete the entry.

When you delete a binding entry, the parameters specified in the undo command must be the same as the corresponding parameters in the binding entry; otherwise, the entry cannot be deleted.
Binding entries can be deleted in a batch, for example:
- Run the undo user-bind static command to delete all binding entries.
- Run the undo user-bind static interface gigabitethernet 0/0/1 command to delete all entries on the specified interface GE0/0/1.
- Run the undo user-bind static vlan 10 command to delete all entries in VLAN 10.

The following example shows how to delete a static binding entry:

Run the display dhcp static user-bind all command to view all static binding entries on the device.
