Policy File Parameters and Syntax
Description
If this value is set to True, the DHCP server performs
a ping before assigning a static DHCP address. If an
ICMP_REPLY is received from the ping, then the
DHCP offer is not sent to the client and the address is
marked as unavailable.
If this value is set to True, the DHCP server performs
a ping before assigning a static BootP address. If an
ICMP_REPLY is received, the BootP reply is not
sent to the client, and the BootP address is marked as
unavailable.
This poilcy is used when the MAC pool addresses are
defined at either the global or the subnet level.
If this value is set to True, the DHCP information is
provided to the clients that have a known MAC
address (configured in a MAC pool). If MAC pool
addresses are not defined at either the global or the
subnet level, the none of the devices are provided a
DHCP lease.
If this value is set to False, the DHCP information is
provided to all clients.
If this value is set to True, the DHCP server sends
only the options requested by the client.
For example, if the client sends a DHCP parameter
request list - option (55) in the Discover packet, then
the server sends only the options that are both
configured and requested by the client.
The subnet-mask (1) and lease-time (51) options are
always sent to the client, in addition to the IP address.
If this value is set to False, the service sends all the
configured options to the client.
If this policy is set to True, the server supports the
assignment of DHCP options by the DOCSIS device
class.
This policy affects the contents of the "ciaddr" field
in outgoing packets.
If this policy is set to True, the service fills in
"ciaddr" with 0.0.0.0 on reply (ACK) packets.
