7Lease
Expiration
SleepTime
Lease
Expiration
SleepTime =
120000
60000
msecs
Specifies the time interval in milli seconds after
which the lease expiration processing occurs.
Note: This value must not be less than 1 minute.
8MaxPending
Seconds
MaxPending
Seconds = 20
10 Specifies the number of seconds that an offered lease
remains in a pending state.
When a client sends a DHCPDISCOVER request, the
DHCP server responds with a DHCPOFFER and
offers an IP address. The address is marked as
pending for the specified period of time.
9Max
Unavailable
Time
Max
Unavailable
Time = 14000
86400 Determines the period of time that an IP address is
not available after a DHCPDECLINE or ping packet
is sent as response. After this time period, the server
considers this address as available.
10 Nak
Unknown
Clients
NakUnknown
Clients =
False
True Prevents the DHCP server from providing DHCP
addresses to clients which are not in the defined
subnets of the DHCP server.
This policy must be set to False in environments
where multiple DHCP services are active in the same
subnet or subnets.
11 NackDhcp
RequestsFor
Duplicates
NackDhcp
RequestsFor
Duplicates
= False
True If this value is set to True, the DHCP server sends a
NAK if a RENEW/REBIND request or SELECTING
request is received for an IP address already owned
by another hardware interface.
If this value is set to False, the invalid request is
dropped.
12 PingAttempts
Ping
Attempts = 3
1 Specifies the number of attempts to ping through
which DHCP server determines if the IP address is
already in use.
13 PingDelay
PingDelay =
200
N/A Specifies the delay in milliseconds between two
consecutive pings to check the IP address usage in the
network.
14 PingSendDelay
PingSend
Delay = 1000
500 Specifies the number of milliseconds between
subsequent pings. This is applicable only if the ping
attempts are greater than 1. If the value of
PingAttempts is greater than 1, then the
PingSendDelay overrides the PingDelay policy.
15 PingRetention
Ping
Retention
= 200
0 Specifies the number of seconds for which a ping is
valid. If a ping is attempted and no response is
returned, then the address is considered to be
available. During the ping retention period, other ping
requests are ignored.
