Description: Manages World Wide Packets Layer 4 traffic classification filters and policy-based forwarding rules.

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-LAYER4-FILTER-MIB?

WWP-LAYER4-FILTER-MIB is a World Wide Packets (WWP) proprietary MIB defining management objects for Layer 4 traffic classification and policy-based forwarding on WWP Ethernet transport products. It focuses on configuration data: defining filters that match on Layer 4 attributes (such as TCP/UDP ports) and the forwarding or QoS policies applied to matching traffic. Its monitoring value is mainly in confirming the software/configuration status of the device -- verifying which filters and forwarding rules are active -- rather than exposing hardware health metrics. As a vendor-specific MIB it likely builds on WWP's broader enterprise MIB tree for interface and switching objects. It is used in metro Ethernet and carrier transport networks built on World Wide Packets equipment (later acquired by Cisco) to enforce traffic engineering policies, and engineers can download the WWP-LAYER4-FILTER-MIB file to load into their MIB browser for reference.

IPNetwork Monitor allows you to monitor SNMP objects defined in WWP-LAYER4-FILTER-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.

Supported Devices

World Wide Packets Ethernet transport switch

Monitoring Examples

No concrete object or table names were provided in the source material for this MIB, so a specific polling scenario naming real objects cannot be constructed; based on the module description, an administrator would typically query the Layer 4 filter and policy tables to confirm a given TCP/UDP port-based classification rule is correctly forwarding or dropping matching traffic.

What Can Be Monitored

Layer 4 filter rule configuration
policy-based forwarding assignment
active traffic classification state

wwpLayer4FilterMIB	1.3.6.1.4.1.6141.2.52			This MIB module defines the mgmt objects to support the layer 4 filtering on the WWP products.

wwpLayer4Filter	1.3.6.1.4.1.6141.2.52.1.1
U32 wwpMaxLayer4Filters	1.3.6.1.4.1.6141.2.52.1.1.1	Unsigned32	read-only	The maximum number of Layer4 Filters that this device supports.
U32 wwpNumLayer4Filters	1.3.6.1.4.1.6141.2.52.1.1.2	Unsigned32	read-only	The current number of Layer4 Filters that are configured in this device.
wwpLayer4FilterTable	1.3.6.1.4.1.6141.2.52.1.1.3		not-accessible	The (conceptual) table listing the config parameters for the Layer 4 filter.
wwpLayer4FilterEntry	1.3.6.1.4.1.6141.2.52.1.1.3.1		not-accessible	An entry (conceptual row) in the wwpLayer4FilterTable.
OCT wwpLayer4FilterName	1.3.6.1.4.1.6141.2.52.1.1.3.1.1	OCTET STRING	read-only	The locally arbitrary, but unique identifier associated with this wwpLayer4FilterEntry.
INT wwpLayer4FilterProtocolNumber	1.3.6.1.4.1.6141.2.52.1.1.3.1.2	INTEGER	read-create	The protocol number for the Layer 4 Filter. The list of protocol numbers are assigned by IANA.
I32 wwpLayer4FilterSrcPort	1.3.6.1.4.1.6141.2.52.1.1.3.1.3	Integer32	read-create	The traffic addressed to the transport layer source port specified by this object will be blocked by this filter. A zero value for this object will indicate that this object should be ignored while applying the filter.
I32 wwpLayer4FilterDstPort	1.3.6.1.4.1.6141.2.52.1.1.3.1.4	Integer32	read-create	The traffic addressed to the transport layer destination port specified by this object will be blocked by this filter. A zero value for this object will indicate that this object should be ignored while applying the filter.
ROW wwpLayer4FilterStatus	1.3.6.1.4.1.6141.2.52.1.1.3.1.5	RowStatus	read-create	Used to manage the creation and deletion of the conceptual rows in this table. To create a row in this table, a manager must set this object to 'createAndGo'. Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the wwpLayer4FilterStatus column can't be set to 'active'. In particular, a newly created row cannot be made active until the corresponding instance of wwpLayer4FilterProtocol has been set. None of the objects can be modified while the value of this object is active(1).
wwpLayer4FilterAttachTable	1.3.6.1.4.1.6141.2.52.1.1.4		not-accessible	The (conceptual) table listing the attachment of created filters to the VLANs and ports. If there is no entry atached with the filter, then filter is virtually disabled.
wwpLayer4FilterAttachEntry	1.3.6.1.4.1.6141.2.52.1.1.4.1		not-accessible	An entry (conceptual row) in the wwpLayer4FilterAttachTable.

INT wwpLayer4FilterAttachType	1.3.6.1.4.1.6141.2.52.1.1.4.1.2	INTEGER	read-create	The attach type for this filter. Setting this object to 'allow' will allow the traffic specified by the filter name.
POR wwpLayer4FilterPortList	1.3.6.1.4.1.6141.2.52.1.1.4.1.3	PortList	read-create	The set of ports on which this filter is to be applied.
I32 wwpLayer4FilterCounterId	1.3.6.1.4.1.6141.2.52.1.1.4.1.4	Integer32	read-create	The stats related to this filter will be stored in the counter specified by this object.
C32 wwpLayer4FilterCount	1.3.6.1.4.1.6141.2.52.1.1.4.1.5	Counter32	read-only	The stats value in the counter specified by the wwpLayer4FilterCounterId.
ROW wwpLayer4FilterAttachStatus	1.3.6.1.4.1.6141.2.52.1.1.4.1.6	RowStatus	read-create	Used to manage the creation and deletion of the conceptual rows in this table. To create a row in this table, a manager must set this object to 'createAndGo'. Until instances of all corresponding columns are appropriately configured, the value of the corresponding instance of the wwpLayer4FilterStatus column can't be set to 'active'. In particular, a newly created row cannot be made active until the corresponding instance of wwpLayer4FilterPortList has been set. None of the objects can be modified while the value of this object is active(1).
