Sets the time to live (TTL) ceiling, in seconds, for DNS records
added through dynamic updates. When the DHCP server adds a DNS
record, it uses a TTL of the minimum of either this ceiling or one
third the lease time.
max-ping-packets int default = 500
Sets the number of buffers the server allocated for sending and
receiving ICMP ping messages. See the 'ping-clients' and
scope 'ping-clients' attribute.
max-waiting-packets rangeint(1-10) default = 6
Sets the maximum number of packets that can wait for a
particular IP address.
The server queues only the most recently received n packets
(of an address) for processing. If an additional packet
associated with that address arrives and n packets are already
queued, the server drops the oldest packet and queues the new
one. It also drops duplicate packets (whose XID, client ID, and
MAC address are the same as one already queued).
Dropped packets are logged if the log setting
dropped-waiting-packets is set. It is off by default.
mcd-blobs-per-bulk-read rangeint(1-2500)
Determines the number of binary large objects (blobs) in a bulk
read. Default 256. Range, 1 to 2500.
Use this attribute to tune DHCP start and reload times.
Generally, a higher value will result in faster server start and
reload time, at the cost of using more memory.
min-dns-ttl time default = 10m
Minimum value for time to live (TTL) in seconds, for DNS records
added through dynamic updates. When the DHCP server adds a DNS
record, the TTL value will be min-dns-ttl if one third the lease
time is less than the min-dns-ttl value.
multicast-addresses ip6addr default = ff02::1:2,ff05::1:3
Controls the default multicast addresses that are enabled
on interfaces. The address ff02::1:2 is required if any
DHCPv6 clients are directly connected to the link associated
with an interface. The address ff05::1:3 is the default
multicast address that relay agents use to relay DHCPv6
requests.
