Configuring the DHCP Server
7.5 Using DHCP GUI to Configure DHCP
• Host name prefix is magic.
Then, the DHCP server gives the host names magic1 and magic2 to the next two
computers that request host names.
Enter a specific host name prefix.
Host names
Specifies the list of host names. Enter as many host names as needed. Different
DHCP servers can own the same host names.
7.5.2.4 Active IP Snapshot
You can use the Active IP Snapshot window to view the lease database, manually
add a new lease, and remove a lease.
Viewing a Lease
The left side of the Active IP Snapshot window lists each DHCP client with a
lease granted by the server. To see the details:
1. Click the Server/Security tab.
2. Choose Active IP Snapshot from the drop-down list.
3. Select a record on the left side of the window.
4. Review the information on the right side of the window. It lists the
information that applies to the selected record.
Adding a New Lease
Typically you only add a new lease when you intend to permanently attach a
hardware address to an IP address. The IP address does not need to come from
the DHCP IP addresses you have defined.
To add a new lease, use the following procedure:
1. Click the Server/Security tab.
2. Choose Active IP Snapshot from the drop-down list.
3. Choose [New Record].
4. Enter a value for each parameter.
5. Click Add.
Changes made to the database take effect immediately.
Note
Ensure that the IP address you specify does not belong to any pool of IP
addresses configured in an IP range. If it does, it could be released and
used by other clients (MAC address).
If you want to grant a lease for an infinite period of time, which effectively
make a permanent binding between an IP address and a MAC address,
set the Lease Expiration parameter to a value of -1.
Removing a Lease
To remove a lease, use the following procedure:
1. Click the Server/Security tab.
