Field Meaning
Maximum Number of
DNS Records Defines the maximum number of static and
dynamic entries.
Once this value is reached, an older dynamic
entry is deleted from the cache when a new
entry is added. The entry deleted is always the
dynamic entry that has not been requested for
the longest period of time.
If Maximum Number of DNS Records is
reduced by the user, dynamic entries are also
deleted, if necessary.
Static entries are not deleted; Maximum
Number of DNS Records cannot be set lower
than the current number of existing static
entries. If Maximum Number of DNS Records
corresponds to the number of static entries, no
further dynamic entries are possible!
Maximum TTL for Pos
Cache Entries Is assigned to a positive dynamic entry in the
cache as TTL if the TTL field of the DNS record
has the value 0 or exceeds Maximum TTL for
Pos Cache Entries.
Maximum TTL for Neg
Cache Entries Is assigned as TTL to a negative dynamic entry
in the cache.
Field Meaning
Received DNS Packets Displays the number of DNS packets received,
including the answer packets for forwarded
requests.
