Attribute

Alarm ID	Alarm Severity	Alarm Type
3276800094	Warning	securityServiceOrMechanismViolation(10)

Parameters

Name	Meaning
OID	Indicates the MIB object ID of the alarm.
IfIndex	Indicates the interface index.
BroadcastMinRate	Indicates the minimum rate of broadcast packets.
BroadcastMaxRate	Indicates the maximum rate of broadcast packets.
MulticastMinRate	Indicates the minimum rate of multicast packets.
MulticastMaxRate	Indicates the maximum rate of multicast packets.
Action	Indicates the storm control action.
Interval	Indicates the interval for detecting storms.
Status	Indicates the interface status, including: blocked: When the rate of receiving packets is greater than the value of MaxRate and the storm control action is block, the status of the interface is block. normal: Packets are normally forwarded. error-down: When the rate of receiving packets is greater than the value of MaxRate and the storm control action is error-down, the status of the interface is error-down.
UnicastMinRate	Indicates the minimum rate of unknown unicast packets.
UnicastMaxRate	Indicates the maximum rate of unknown unicast packets.
BroascastMode	Indicates the storm control mode of broadcast packets.
MulticastMode	Indicates the storm control mode of multicast packets.
UnicastMode	Indicates the storm control mode of unknown unicast packets.

Impact on the System

Storms may occur if the threshold is exceeded. Services are not affected.

Possible Causes

The interface traffic volume is greater than the upper threshold or smaller than the lower threshold.

Procedure

Run the display storm-control interface command to check the storm control configuration on the interface.
If the interface status is error-down, check whether the interface can be enabled according to the application scenario.
- If yes, run the shutdown and undo shutdown command manually. Then go to step 4.
- If not, go to step 3.
Collect the device configurations, alarms, and logs, and then contact technical support personnel.
End.
