Juniper EX3400 Features Guide

interfaces-vlan—(Optional) Clear the binding state on the interface VLAN ID and S-VLAN
ID.
interfaces-wildcard—(Optional) Clear bindings on a set of interfaces. This option supports
the use of the wildcard character (*).
logical-system logical-system-name—(Optional) Clear the binding state for DHCP
clients on the specified logical system.
routing-instance routing-instance-name—(Optional) Clear the binding state for DHCP
clients on the specified routing instance.
dual-stack—(Optional) Remove either both arms or single arm of dual-stack.
NOTE:
• The dual-stack command is added in the syntax removes both arms
of the dual-stack with a single command entry.
• When the dual-stack command is not added in the syntax, the clear
dhcpv6 server binding command clears only the family specific arm of
the dual-stack.
