Description: Manages broadcast and multicast storm control thresholds and suppression on Avaya/Nortel ERS switch ports.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is BAY-STACK-STORM-CONTROL-MIB?

BAY-STACK-STORM-CONTROL-MIB manages broadcast, multicast, and unicast storm control suppression on Avaya/Nortel Ethernet Routing Switch ports. It exposes per-port, per-traffic-type configuration objects covering enable state, high/low watermark thresholds, polling interval, trap interval, and the action to take when a threshold is crossed, alongside a scalar poll value. Monitoring this data lets an operator see whether a port is actively suppressing a traffic storm and how close current traffic levels are to the configured thresholds - directly indicating a software/configuration response to abnormal traffic conditions on the link. It functions as a vendor-specific extension layered alongside standard interface and bridge MIBs rather than replacing them. It is deployed on enterprise access switches to protect LAN segments from broadcast storms and loop-induced flooding. Engineers can download the BAY-STACK-STORM-CONTROL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BAY-STACK-STORM-CONTROL-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Avaya/Nortel Ethernet Routing Switches

Monitoring Examples

An administrator checks bsStormControlTable/bsStormControlEntry for a port's bsStormControlTrafficType, bsStormControlHighWatermark, and bsStormControlActionType settings. A port repeatedly generating entries in bsStormControlNotifications because its measured traffic (via bsStormControlPollValue) exceeds bsStormControlHighWatermark indicates a broadcast storm or loop on that segment, triggering the configured suppression action such as a port shutdown.

What Can Be Monitored

storm control enabled state
monitored traffic type
high/low watermark thresholds
poll interval
configured action on threshold breach
storm notifications

OIDs

OID symbolic	OID numeric	Type	Access	Description
bayStackStormControlMib	1.3.6.1.4.1.45.5.42			This MIB module is used for Storm Control configuration. The Storm Control feature prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on an interface.
bsStormControlNotifications	1.3.6.1.4.1.45.5.42.0
NTF bsStormControlBelowLowWatermark	1.3.6.1.4.1.45.5.42.0.1			This notification is generated when the storm control packet type rate falls below the low watermark after having risen above the high watermark. It is generated only once when this occurs.
NTF bsStormControlAboveHighWatermark	1.3.6.1.4.1.45.5.42.0.2			This notification is generated periodically as long as the storm control packet type rate remains above the high watermark.
bsStormControlObjects	1.3.6.1.4.1.45.5.42.1
bsStormControlScalars	1.3.6.1.4.1.45.5.42.1.1
U32 bsStormControlPollValue	1.3.6.1.4.1.45.5.42.1.1.1	Unsigned32	accessible-for-notify	The polled value when a notification is generated.
bsStormControlTable	1.3.6.1.4.1.45.5.42.1.2		not-accessible	This table is used to configure storm control global settings.
bsStormControlEntry	1.3.6.1.4.1.45.5.42.1.2.1		not-accessible	An entry containing objects for controlling storm control settings.
INT bsStormControlTrafficType	1.3.6.1.4.1.45.5.42.1.2.1.1	INTEGER	not-accessible	Storm control traffic type.
T/F bsStormControlEnabled	1.3.6.1.4.1.45.5.42.1.2.1.2	TruthValue	read-write	Indicates whether storm control is enabled for this instance.
U32 bsStormControlLowWatermark	1.3.6.1.4.1.45.5.42.1.2.1.3	Unsigned32	read-write	Low watermark for storm control of this instance. If the rate drops below this value after having risen above the high watermark, a single notification will be generated.
U32 bsStormControlHighWatermark	1.3.6.1.4.1.45.5.42.1.2.1.4	Unsigned32	read-write	High watermark for storm control of this instance. If the rate rises above this value, notifications will be generated at the rate give by the bsStormControlTrapInterval object.
NUM bsStormControlPollInterval	1.3.6.1.4.1.45.5.42.1.2.1.5	TimeInterval	read-write	The polling interval for checking the packet rate for storm control of this instance.
I32 bsStormControlTrapInterval	1.3.6.1.4.1.45.5.42.1.2.1.6	Integer32	read-write	The rate for sending storm control notifications, measured in a number of polling intervals.
INT bsStormControlActionType	1.3.6.1.4.1.45.5.42.1.2.1.7	INTEGER	read-write	Storm control action type for this instance.
bsStormControlIfTable	1.3.6.1.4.1.45.5.42.1.3		not-accessible	This table is used to control storm control settings per-interface.
bsStormControlIfEntry	1.3.6.1.4.1.45.5.42.1.3.1		not-accessible	An entry containing objects for controlling storm control settings for an interface.
NUM bsStormControlIfIndex	1.3.6.1.4.1.45.5.42.1.3.1.1	InterfaceIndex	not-accessible	The ifIndex value of the interface.
T/F bsStormControlIfEnabled	1.3.6.1.4.1.45.5.42.1.3.1.2	TruthValue	read-write	Indicates whether storm control is enabled for this instance.
U32 bsStormControlIfLowWatermark	1.3.6.1.4.1.45.5.42.1.3.1.3	Unsigned32	read-write	Low watermark for storm control of this instance. If the rate drops below this value after having risen above the high watermark, a single notification will be generated.
U32 bsStormControlIfHighWatermark	1.3.6.1.4.1.45.5.42.1.3.1.4	Unsigned32	read-write	High watermark for storm control of this instance. If the rate rises above this value, notifications will be generated at the rate give by the bsStormControlTrapInterval object.
NUM bsStormControlIfPollInterval	1.3.6.1.4.1.45.5.42.1.3.1.5	TimeInterval	read-write	The polling interval for checking the packet rate for storm control of this instance.
I32 bsStormControlIfTrapInterval	1.3.6.1.4.1.45.5.42.1.3.1.6	Integer32	read-write	The rate for sending storm control notifications.
