### Description

```asn1
hubOptionalModuleBcastPacketRateThreshold OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-write
STATUS mandatory
DESCRIPTION
"Specify the threshold value of broadcast packet rate for a given
optional module. Once the rate of broadcast packets received on
any one of port of a given optional module is over the specified
threshold value, it indicates that broadcast storming may occurred
on this segment.
The optional module broadcast packet rate is defined as following:
Segment Broadcast Packet Rate
Total Number of Broadcast Packet Received on the Optional Module
= -------------------------------------------------------------------
Sampling Interval
where the Sampling Interval = 1 second.
The optional module broadcast storming is determined if the following
conditions are satisfied:
1. The rate of broadcast packets received on a given segment is
over the threshold value specified by hubSegBcastPacketRateThreshold.
2. The rate of broadcast packets received on any one of port of a
given optional module is over the specified threshold value by
this object.
Once the broadcast storm is detected on an optional module, the
action specified by the object hubBcastAlarmAction will be taken
on that optional module. Beside, the value 'detected(1)' will be set
to the object hub3PortBridgeModuleBcastStormDetected."
