Viewing and Deleting DHCP Client Bindings

The JUNOSe software provides commands that enable you to manage your router's
DHCP external server, DHCP local server, and DHCP relay proxy client bindings. A
client binding associates an IP address with a DHCP client, and describes both the
client (for example, hardware address and state) and the IP address (for example,
subnet and lease time).
The following commands enable you to view information about current DHCP client
bindings:

to specify (filter) the client bindings you want to delete:
