Manage network services

Management > Network Services displays information about active network services. Currently,

the only network-service management task possible from this page is managing the DHCP server.

Manage DHCP server operation

DHCP server management operations include:

 View DHCP server status.

 Start/stop/restart the DHCP server.

 View and manage current DHCP leases.

Start, stop, and restart the DHCP server

The DHCP Server Management page shows the current status of the DHCP server. Depending on

the current status, there are buttons to start, stop, or restart the DHCP server. Click the appropriate

button to perform your request.

Note

Stopping, restarting, or rebooting the DHCP server causes all information on IP

address leases to be lost. All leased addresses except for reservations will be returned

to the available address pool and may be served in a new lease to a DHCP client.

View and manage current DHCP leases

The DHCP server maintains a current list of its leases, reservations and unavailable addresses. The

displayed lease list may contain entries that report a variety of status descriptions. The Lease Status

types are identified and described below.

Even after a lease has expired or is released by a DHCP client, the associated IP address is not

immediately returned to the available address pool. Rather, there is a non-configurable

grace period during which the lease record is retained by the DHCP server. At the end of that

grace period, the lease record is automatically deleted and the associated IP address is returned to

the available address pool. Where a grace period is observed, this is indicated in the Lease Status

descriptions below.

The grace period is incorporated in the DHCP server to increase the consistency of offering the

same IP address to a DHCP client, even if that client is rebooted or off the network for a period of

time that does not exceed the grace period.

Leases can be removed from the DHCP server while the server is running. To remove a lease,

select the checkbox to the left of the lease information in the table of leases, then click the Remove

button below the lease table. To remove all leases, select the checkbox to the left of the descriptive

headings at the top of the table, then click the Remove button below the lease table.

Note

Removing a lease will cause the associated IP address to be returned immediately to

the available address pool. Any IP address in this available address pool may be

served in a new lease to a DHCP client. Static lease reservations will always display

in the lease list. These reservation leases may be removed, but a new lease will be

created immediately. To disable or permanently remove a reservation, use the DHCP

server Settings page in the Network Configuration area.
