Options
| address | (Optional) Clear the binding state for the DHCP client, using one of the following entries:
|
| all | (Optional) Clear the binding state for all DHCP clients. |
| dual-stack | (Optional) Clear the binding state for DHCPv4 clients and the associated DHCPv6 bindings in the single-session DHCP dual stack. DHCPv6 clients created in a DHCPv6-only stack are not affected. |
| interface interface-name | (Optional) Clear the binding state for DHCP clients on the specified interface. |
| interfaces-vlan | (Optional) Clear the binding state on the interface VLAN ID and S-VLAN ID. |
| interfaces-wildcard | (Optional) The set of interfaces on which to clear bindings. This option supports the use of the wildcard character (*). |

clear dhcp relay binding
The following sample output displays the address bindings in
the DHCP client table before and after the clear dhcp relay binding command is issued.

clear dhcp relay binding all
The following command clears all DHCP relay agent bindings:
user@host> clear dhcp relay binding all
clear dhcp relay binding dual-stack all
The following command clears all DHCP relay agent bindings for all DHCPv4 clients and the associated DHCPv6 bindings in the single-session DHCP dual stack. DHCPv6 clients created in a DHCPv6-only stack are not affected.
user@host> clear dhcp relay binding dual-stack all
clear dhcp relay binding interface
The following command clears DHCP relay agent bindings on a specific interface:
user@host> clear dhcp relay binding interface fe-0/0/3
clear dhcp relay binding <interfaces-vlan>
The following command uses the interfaces-vlan option to clear all DHCP relay agent bindings on top of the underlying
interface ae0, which clears DHCP bindings on all demux
VLANs on top of ae0:
user@host> clear dhcp relay binding interface ae0
clear dhcp relay binding <interfaces-wildcard>
The following command uses the interfaces-wildcard option to clear all DHCP relay agent bindings over a specific interface:
user@host> clear dhcp relay binding ge-1/0/0.*
