Release Information Command introduced in Junos OS Release 8.3.
Options all and interface added in Junos OS Release 8.4.
Options interfaces-vlan and interfaces-wildcard added in Junos OS Release 12.1.
Command introduced in Junos OS Release 12.1X48R3 for PTX Series Packet Transport
Routers.
Option dual-stack added in Junos OS Release 15.1.
Description Clear the binding state of a Dynamic Host Configuration Protocol (DHCP) client from
the client table.
Options address—(Optional) Clear the binding state for the DHCP client, using one of the following
entries:
• ip-address—The specified IP address.
• mac-address—The specified MAC address.
• session-id—The specified session ID.
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 (*).
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.
