scope is examined to find an available lease or whenever a
scope is examined to determine if a lease is still acceptable
for a client who already has one. It can be very useful when
configuring or debugging client-class scope criteria
processing. It causes moderate amount of information to be
logged and should not be left enabled as a matter of course.
unknown-criteria
This setting will cause a single line log message to appear
whenever a client entry is found which specifies selection
criteria that is not found in any scope appropriate for that
client's current network location.
dns-update-detail
This setting causes the server to log a message as it sends
each dns update and as it receives replies to update messages.
ldap-query-detail
This setting will cause log messages to appear whenever the
dhcp server initiates a query to LDAP server, receives response
and retrieves result or error messages.
ldap-update-detail
This setting will cause log messages to appear whenever the
dhcp server initiates an update lease state to LDAP server,
receives response and retrieves result or error messages.
ldap-create-detail
This setting will cause log messages to appear whenever the
dhcp server initiates an lease state entry create to LDAP
server, receives response and retrieves result or error
messages.
leasequery
This setting will cause log messages to appear when leasequery
packets are processed without internal errors and result in
an ACK or a NAK.
dropped-waiting-packets
If the value of max-waiting-packets is non-zero packets may
be dropped if the queue length for any IP address exceeds the
value of max-waiting-packets. If dropped-waiting-packets
is set, the server will log a message whenever it drops a
waiting packet from the queue for an IP address.
no-success-messages
This setting will cause the single line message that is
normally logged for every successful outgoing DHCP response
packet to not appear. It affects logging only for successful
outgoing DHCP response packets.
no-dropped-dhcp-packets
This setting will cause a single line message normally logged
for every DHCP packet that is dropped due to DHCP
configuration to not appear. (See no-invalid-packets for
messages associated with packets dropped because they are
invalid.)
no-dropped-bootp-packets
This setting will cause the single line message normally
logged for every BOOTP packet that is dropped to not appear.
no-failover-activity
This setting will cause normal activity and some warning
messages logged for failover to not appear. Serious error
log messages will continue to appear independent of this
log-setting.
