show dhcp server binding
Syntax
Release Information
Command introduced in Junos OS Release 9.0.
Options interfaces-vlan and interfaces-wildcard added in Junos OS Release 12.1.
Description
Display the address bindings in the client table on the extended Dynamic Host Configuration Protocol (DHCP) local server.
![]() | Note: If you delete the DHCP server configuration, DHCP server bindings might still remain. To ensure that DHCP bindings are removed, issue the clear dhcp server binding command before you delete the DHCP server configuration. |
Options
address | — | (Optional) Display DHCP binding information for a specific client identified by one of the following entries:
|
brief | detail | summary | — | (Optional) Display the specified level of output about active client bindings. The default is brief, which produces the same output as show dhcp server binding. |
interface interface-name | — | (Optional) Display information about active client bindings on the specified interface. You can optionally filter on VLAN ID and SVLAN ID. |
interfaces-vlan | — | (Optional) Show the binding state information on the interface VLAN ID and S-VLAN ID. |
interfaces-wildcard | — | (Optional) The set of interfaces on which to show the binding state information. This option supports the use of the wildcard character (*). |
logical-system logical-system-name | — | (Optional) Display information about active client bindings for DHCP clients on the specified logical system. |
routing-instance routing-instance-name | — | (Optional) Display information about active client bindings for DHCP clients on the specified routing instance. |
