.1.3.6.1.2.1.234.2.3.1.14
Object
column
r/w
Percent Integer32
Threshold for reporting low utilization of the address pool.
Utilization at a given instant is calculated as the
percentage of ports allocated in port map entries for the
most-used protocol at that instant. If utilization is less
than or equal to natv2PoolThresholdUsageLow, an instance of
natv2NotificationPoolUsageLow may be triggered, unless
disabled by setting it to -1. Reporting is subject to the
per-pool notification interval given by
natv2PoolNotificationInterval. If multiple notifications
are triggered during one interval, the agent MUST report
only the one with the lowest value of
natv2PoolNotifiedPortMapEntries and discard the others.
Implementation note: the percentage specified by this object
can be converted to a number of port map entries at
configuration time (after port and address ranges have been
configured or reconfigured) and compared to the current
value of natv2PoolNotifiedPortMapEntries.
