| etsysFlowLimitingSystemState |
.1.3.6.1.4.1.5624.1.2.43.1.1.1 |
|
The current state of the active part of the Flow Limiting
feature.
enabled (1) - All aspects of Flow Limiting are operational.
disabled (2) - Flow Limiting is configurable but no actions
are taken, no notifications are generated
and no interfaces will be disabled.
All statistical information is still gathered
and available.
When this object is set to disabled the Flow Limiting feature
MUST release its control on all interfaces. Any interfaces
that had been operationally held in the 'down' state MUST be
allowed to attain their currently correct operational state.
Any flows created by the Flow Limiting feature MUST be removed.
Maintaining the value of this object across agent reboots is
REQUIRED.
|
| etsysFlowLimitingSystemSnmpNotifications |
.1.3.6.1.4.1.5624.1.2.43.1.1.2 |
|
The current state of the SNMP Notification functionality in
the Flow Limiting feature.
enabled (1) - Flow Limiting will generate SNMP Notifications
for flow counts and setup rates that exceed the
configured limits. The Flow Limiting feature
MUST be enabled for SNMP Notifications to be
generated.
disabled (2) - Flow Limiting will not generate SNMP
Notifications under any conditions.
A notification is generated when a value is first detected
above its respective configured limit. That notification
MUST NOT be generated again until the respective value has
transitioned through its respective limit in both directions.
Agents are not required to generate SNMP Notifications for
conditions that exist when this object is set to enabled.
SNMP Notifications MAY only be generated after additional
flow setups are detected that exceed the configured limits
on that interface.
Maintaining the value of this object across agent reboots is
REQUIRED.

.1.3.6.1.4.1.5624.1.2.43.1.1.3 |
|

the Flow Limiting feature.
enabled (1) - Flow Limiting will shutdown an interface when
the conditions on that interface exceed the
configured values, one of the specified actions
is to disable the interface, and the Flow
Limiting feature is enabled.
disabled (2) - Flow Limiting will not shutdown any interface
under any conditions.
When this object is set to disabled the Flow Limiting feature
MUST release its control on all interfaces. Any interfaces
that had been operationally held in the 'down' state MUST be
allowed to attain their currently correct operational state.
Agents are not required to shutdown interfaces for conditions
that exist when this object is set to enabled. Interfaces
MAY only be shutdown after additional flow setups are detected
that exceed the configured limits on that interface.
Maintaining the value of this object across agent reboots is
REQUIRED.

the case of a flow counter or rate that is repeatedly
transitioning across a threshold. A value of zero
indicates that the entity should not suppress any
notifications related to the Flow Limiting feature.
Maintaining the value of this object across agent reboots
is REQUIRED.

Setting this object to disabled(2) will disable the
active part of the Flow Limiting feature as defined
for the etsysFlowLimitingSystemState object on this
interface.
When the value of this object changes from enabled(1)
to disabled(2) the agent MUST:
