Non-ageing entries
— If the ageing time is set to 00:00, all ageing
entries in the database are defined as non-ageing entries. This means
that they do not age, but they are still deleted if the Switch 1005 is
reset. For more information about setting an ageing time, see see
■
Permanent entries
— Permanent entries are retained in the database
if the Switch 1005 is reset or a power off/on cycle occurs. It is up to the
system administrator to make entries permanent. You can do this with
single addresses or all addresses in the database using an SNMP
Network Manager. All entries entered via the switch database are
stored as permanent.
