smMlmDiscoveryNodeExpirationPeriod OBJECT-TYPE
SYNTAX DisplayString
ACCESS read-write
STATUS mandatory
DESCRIPTION
"This field specifies the amount of time a node remains
in the table of discovered nodes. Setting this field
allows nodes that have not been heard from to be removed
from the discovered nodes table. If this field is blank,
nodes are NEVER removed from the discovered nodes table.
However, if the same Network Address is used with a new
MAC Address, the MAC address of the existing entry
is changed and a trap is sent.
The node expiration period is specified using decimal values
appended by the unit: d - day, h - hour, m - minute,
s - second, u - millisecond. If no unit is appended,
the value is minutes. Multiple values/units are
allowed (i.e. 1h45m = 1 hour, 45 minutes). The default
for this field is 7d (7 days).
It is a good idea to perform an active search at least
as often as this node expiration time period to avoid
losing nodes that are not initiating communication
(e.g. file servers, bridges, hubs, etc.). However,
nodes of this type that are being status checked by
the status checker table will continue to exist."
