Specifying DHCP server parameters

To specify DHCP server parameters using the DHCP Server Manager:

1. Select Server Edit Server Parameters.

2. You can specify the following parameters:

   Initial lease reservation time

   Define the time in minutes for which an address is reserved while the server offers it to a client. The lease begins when the client accepts the address. This reservation period prevents an address from being offered to more than one client at the same time. The default value is 10 minutes.

   Pad lease by (percent)

   Enter the amount of time, as a percentage of the lease, that you want to extend the lease to allow for clock drift between the server and the client. The default is 1% of the lease. The unpadded lease is known to the client. The DHCP server knows the padded lease so preventing the server from thinking that the lease has expired before the client does.

   Probe addresses

   Specify if you want the server to ping an address before it is allocated to make sure it is free.

   DHCP option overload

   Specify if you wish to use option overload. Enabling this option allows the server to use the sname or file fields to carry DHCP options if the options field is full.

   Click on OK.

1. Select Server Address Allocation Server.

2. If the AAS server runs on the same host as the DHCP server, select Local.

   If the AAS server does not run on the same host as the DHCP server, select Remote, enter the IP address of the AAS server, and enter a password that will authenticate the DHCP server to the AAS server.

3. Click on OK.
