Description: Manages Ciena LEOS broadcast traffic containment thresholds and rate limiting per port for storm control.

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 WWP-LEOS-BROADCAST-CONTAINMENT-MIB?

WWP-LEOS-BROADCAST-CONTAINMENT-MIB is a proprietary MIB from World Wide Packets (later part of Ciena), running on their LEOS switch operating system, for configuring broadcast traffic containment (storm control) on a per-port basis. It exposes per-port broadcast rate thresholds and the resulting containment/alarm state when those thresholds are exceeded. Its monitoring role centers on traffic-threshold and alarm status rather than physical component health: a port entering a containment/alarm state signals it is being hit with excessive broadcast traffic, which can indicate a loop, a misbehaving host, or an attack. It complements the standard IF-MIB for identifying which physical interface a given containment configuration and alarm applies to. It is deployed on Ciena/WWP LEOS-based Ethernet switches used in carrier Ethernet access networks where broadcast storms need to be contained per-customer or per-port. Engineers can download the WWP-LEOS-BROADCAST-CONTAINMENT-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWP-LEOS-BROADCAST-CONTAINMENT-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.

Monitoring Examples

No sample objects were provided for this module, so a concrete polling scenario with real object names cannot be constructed; consistent with its stated purpose, monitoring would involve checking each port's configured broadcast rate threshold against its current containment/alarm status, with a port entering an alarmed state flagging a broadcast storm on that segment.

What Can Be Monitored

per-port broadcast rate threshold configuration
broadcast containment/alarm status
storm control enable state

OIDs

OID symbolic	OID numeric	Type	Access	Description
wwpLeosBroadcastContainmentMIB	1.3.6.1.4.1.6141.2.60.8			This MIB module is for the Broadcast containment for WWP Products
wwpLeosBroadcastContainmentMIBObjects	1.3.6.1.4.1.6141.2.60.8.1
WWP wwpLeosBroadcastContainmentCapability	1.3.6.1.4.1.6141.2.60.8.1.1	WwpLeosBroadcastContainmentCapabilitiesMap	read-only	It shows which of the following (wwpLeosBroadcastContainmentPortId or wwpLeosBroadcastContainmentVlanId or both) can be used as an index in wwpLeosBroadcastContainmentFilterMemTable. If bit 0 of the bit mask (starting from right to left) is set to 1 then wwpLeosBroadcastContainmentVlanId can be used as index. If bit 1 of the bit mask is set to 1 then wwpLeosBroadcastContainmentPortId can be used as index. If both bits are set to 1 then both can be used as index.
C32 wwpLeosBroadcastContainmentPktDroppedStats	1.3.6.1.4.1.6141.2.60.8.1.2	Counter32	read-only	Displays the global dropped packets statistics for all VLANs and ports.

I32 wwpLeosBroadcastContainmentIndex	1.3.6.1.4.1.6141.2.60.8.1.4.1.1	Integer32	read-only	Unique index into the table.
STR wwpLeosBroadcastContainmentFilterName	1.3.6.1.4.1.6141.2.60.8.1.4.1.2	DisplayString	read-create	Specifies the name of the filter. If wwpLeosBroadcastContainmentFilterName is not set during filter creation then filter will be created with no name. Filter name can be set later by setting this object.
I32 wwpLeosBroadcastContainmentPktLimit	1.3.6.1.4.1.6141.2.60.8.1.4.1.3	Integer32	read-create	The maximum number of broadcast packets which can be received by this device. Setting this object to 0 will make the broadcast pkt limit as unlimited.
T/F wwpLeosBroadcastContainmentPktDropState	1.3.6.1.4.1.6141.2.60.8.1.4.1.4	TruthValue	read-only	This object if True, specifies that packets were dropped for the given filter since it was last read. If this object reads false then no packet was dropped since it was last read.
ROW wwpLeosBroadcastContainmentStatus	1.3.6.1.4.1.6141.2.60.8.1.4.1.5	RowStatus	read-create	To create a row in this table, a manager must set this object to 'createAndGo'. To delete the entry set this to destroy. To update this entry this object may not be set.
I32 wwpLeosBroadcastContainmentKbps	1.3.6.1.4.1.6141.2.60.8.1.4.1.6	Integer32	read-create	The maximum number of broadcast packets which can be received by this device.
U32 wwpLeosBroadcastContainmentClassifier	1.3.6.1.4.1.6141.2.60.8.1.4.1.7	Unsigned32	read-create	The classifier type for the filter. The value of this object could be any of the below or addition of any of the below: ClassifierType_Unknown(0) ClassifierType_Broadcast(1) ClassifierType_UnknownL2Multicast(2) ClassifierType_UnknownUnicast(4) ClassifierType_UnknownIpMulticast(8) ClassifierType_AllMultcast(16) For example, if the user wants to set the classifier type for the filter as broadcast+unknown_unicast, the value of the object should be set as 5 (1 + 4). Similary if the preferred classifier type is All_flooding, the value would be 15 (1+2+4+8). By default, the classifier type is 3 (broadcast + unknownL2Multicast). When resource mode is disabled, the only supported multicast option is ClassifierType_AllMulticast. The L2 and IP multicast options are controlled individually if resource mode is enabled.
