<div><p>The DHCP Server Monitor can help you to monitor and manage leases.</p>
|
|
<p>The DHCP configuration tool helps you set up the DHCP server, the clients
|
|
it will serve, and the information that is sent to the clients. In the DHCP
|
|
configuration tool, you specify the IP address pool that DHCP will manage
|
|
and the lease times for those address pools. If you want to see which of the
|
|
IP addresses are currently being leased, you need to use the DHCP Server Monitor.</p>
|
|
<p>The DHCP Server Monitor is provided to monitor active lease information
|
|
for an IBM<sup>®</sup> iSeries™ DHCP
|
|
server. This graphical interface allows you to view which IP addresses are
|
|
leased, how long they have been leased, and when they will be available to
|
|
lease out again.</p>
|
|
<p>You can also use the DHCP Server Monitor to reclaim IP addresses that are
|
|
no longer being used. If the DHCP address pool has been exhausted, you can
|
|
look through the active lease information to determine if there are any leases
|
|
that you might want to delete, making the IP address available to other clients.
|
|
For example, you might have a client that is no longer on the network, but
|
|
still has an active IP address lease. You can delete the active IP address
|
|
lease for this client. You should only perform this operation when you are
|
|
certain that the client will no longer attempt to use the address. The DHCP
|
|
server will not notify the clients when you delete their active IP address
|
|
lease. If you delete an active lease for a client that is still on the network
|
|
without releasing the IP address from the client, you might end up with duplicate
|
|
IP address assignments on your network.</p>
