show dhcp server binding
Syntax
show dhcp server binding<address><interfaces-vlan><brief | detail | summary><interface interface-name><interface-tag interface-tag-name><interfaces-vlan><interfaces-wildcard><logical-system logical-system-name><routing-instance routing-instance-name>
Description
Display the address bindings in the client table on the extended Dynamic Host Configuration Protocol (DHCP) local server.
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 |
| interface interface-name |
(Optional) Display information about active client bindings on the specified interface. You can optionally filter on VLAN ID and SVLAN ID. |
| interface-tag interface-tag-name |
(Optional) Displays the binding information for the specified interface-tag. |
| 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. |
