hpicfFfBcastStormControlRisingpps OBJECT-TYPE
• Syntax Integer32 (1..10000000)
• max-access: read-write
• status: current
• description: This object indicates the rising threshold for broadcast storm control. This value is in packets-per-
second of received broadcast traffic. hpicfffbcaststormcontrolaction object takes action when broadcast
traffic reaches this level.
::= {hpicfFfBcastStormControlPortConfigEntry 4}
hpicfFfBcastStormControlAction OBJECT-TYPE
• Syntax integer: none(1), warn(2), warnanddisable(3)
• max-access: read-write
• status: current
• Description: This object defines the action taken by the switch when a broadcast storm occurs on a port. A
value of none (1) indicates that no action is performed. A value of warn (2) indicates that an event is logged
when broadcast traffic crosses the threshold value set on that port. A value of warn-and-disable (3) indicates
that the port is disabled and an event is logged as soon as the broadcast traffic reaches the threshold value
set on that port.
• DEFVAL: none
::= {hpicfFfBcastStormControlPortConfigEntry 5}
hpicfFfBcastStormControlPortDisableTimer OBJECT-TYPE
• Syntax Unsigned32 (0..604800)
• Units: seconds
• max-access: read-write
• status: current
• Description: This object specifies the time period for which the port remains in disabled state. A port is disabled
when broadcast traffic reaches the threshold value set on that port. This time period is specified in seconds.
The default value is zero which means that the port remains disabled and is not enabled again.
• DEFVAL {0}
::= {hpicfFfBcastStormControlPortConfigEntry 6}
Multicast Storm Control
Overview
A multicast storm arises when excessive multicast traffic is exchanged on network ports. Excessive traffic
includes more than expected traffic, or which exceeds a limit value or some percentage of network traffic, or a
percentage of network channel capacity.
To prevent this, a warning message, along with port-shutdown option, is displayed to the user when the network
detects similar multicast packets. At this time, the user can disable the port temporarily and enable it again, or
permanently disable it.
