Chapter 7: DHCP Configuration Guide

Configuring DHCP Server Parameters

You can configure several “global” parameters that affect the behavior of the DHCP server itself.

To configure global DHCP server parameters, enter the following commands in Configure mode:

Specify a remote location to back up	dhcp	global	set	lease-database <url>
the lease database.

Specify the intervals at which the	dhcp	global	set	commit-interval <hours>
lease database is updated.

Updating the Lease Database

After each client transaction, the DHCP server does not immediately update the information in the lease database. Lease update information is stored in flash memory and flushed to the database at certain intervals. You can use the dhcp global set commit- interval command to specify this interval; the default is one hour.

To force the DHCP server to immediately update its lease database, enter the following command in Enable mode:

Force the server to update its lease database.

dhcp flush

Monitoring the DHCP Server

To display information from the lease database:

Show lease database information.

dhcp show binding [activeexpiredstatic]

To display the number of allocated bindings for the DHCP server and the maximum number allowed::

Show the number of allocated bindings for the DHCP server.

dhcp show num-clients
