Policy File Parameters and Syntax
Description
Determines how the expired leases are handled.
The following values are available:
Off - prevents expired leases from being
automatically deleted after lease period is over.
Full_delete - causes the lease from DHCP
database to be deleted, and the Message Service to be
notified of expired leases.
Configures the service to ignore multiple discover,
request, and BootP messages that have the same XID.
Specifies the default lease period provided for the
clients in seconds.
Allows administrators to configure the DHCP server
to ignore inform packets.
If this policy is set to True, the DHCP server
prevents the processing of DHCPINFORM packets.
However, the incoming packets are parsed.
If this policy is set to True, the DHCP server checks
all incoming packets for a zero MAC address and
drops the packet if it is found.
Note: DHCPINFORM messages are processed even
if this process is set to true.
Determines if the service verifies the lease request
from the client before issuing a lease.
The values associated with this policy are as follows:
•
None - Allows the server to issue leases from any
IP address range to an incoming client request.
•
Both - Forces the service to match for both user
and vendor class with the values defined for a
particular IP address range.
•
Vendor - The service must match only on the
vendor class.
•
User - The service must match only on user class.
If this policy is set to True, the DHCP server
provides the requested lease time to the client.
If this policy is set to False, the server offers the
configured lease time.
