Description: Provides generic management objects for Virtual Private LAN Service configurations, instances, and associated pseudowires.

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 VPLS-GENERIC-DRAFT-01-MIB?

VPLS-GENERIC-DRAFT-01-MIB is an IETF draft MIB that defines generic managed objects for Virtual Private LAN Service configurations, instances, and associated pseudowires, intended to be signaling-protocol-agnostic (usable with either the BGP- or LDP-signaled variants described in RFC 4761 and RFC 4762). It exposes VPLS instance configuration, pseudowire associations, and service-level status independent of which signaling mechanism is used underneath. As a service-layer MIB its monitoring role is tracking VPLS instance and pseudowire operational state rather than physical hardware health, though it complements chassis/hardware MIBs on the same PE device. It has an explicit dependency on an underlying pseudowire network and is meant to be used together with the protocol-specific VPLS signaling MIBs (BGP or LDP variants). As a VPLS-GENERIC-DRAFT-01-MIB reference, it applies broadly to carrier PE routers offering multipoint Ethernet VPN services regardless of the specific signaling protocol chosen.

IPNetwork Monitor allows you to monitor SNMP objects defined in VPLS-GENERIC-DRAFT-01-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

Provider Edge (PE) router
vendor-neutral, standards-based MIB, not tied to a specific manufacturer

Monitoring Examples

No object or table names were extracted from this module, so a concrete monitoring walk-through cannot be grounded in specific identifiers; in principle it would let an operator check generic VPLS instance and pseudowire status fields common to both BGP- and LDP-signaled deployments. Without verified object names, more specific technical detail would not be traceable to the actual MIB content.

What Can Be Monitored

VPLS instance configuration
pseudowire association status
generic VPLS service state

How to Use in IPNetwork Monitor

Example using jnxVplsStatusPeerCount OID:

Select a Provider Edge (PE) router, vendor-neutral, standards-based MIB (signaling-agnostic VPLS instance/pseudowire status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type jnxVplsStatusPeerCount into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. This objects specifies the number of peers present in this vpls instance. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

NTF jnxVplsStatusChanged	1.3.6.1.4.1.2636.5.8.0.1			The jnxVplsStatusChanged notification is generated when there is a change in the administrative or operating status of a VPLS service.
NTF jnxVplsFwdFullAlarmRaised	1.3.6.1.4.1.2636.5.8.0.2			The jnxVplsFwdFullAlarmRaised notification is generated when the utilization of the Forwarding database is above the value specified by jnxVplsConfigFwdFullHighWatermark.

jnxVplsObjects	1.3.6.1.4.1.2636.5.8.1
U32 jnxVplsConfigIndexNext	1.3.6.1.4.1.2636.5.8.1.1	Unsigned32	read-only	This object contains an appropriate value to be used for jnxVplsConfigIndex when creating entries in the jnxVplsConfigTable. The value 0 indicates that no unassigned entries are available. To obtain the value of jnxVplsConfigIndex for a new entry in the jnxVplsConfigTable, the manager issues a management protocol retrieval operation to obtain the current value of jnxVplsConfigIndex. After each retrieval operation, the agent should modify the value to reflect the next unassigned index. After a manager retrieves a value the agent will determine through its local policy when this index value will be made available for reuse.

None of the read-create objects values can be changed when jnxVplsConfigRowStatus is in the active(1) state. Changes are allowed when the jnxVplsConfigRowStatus is in notInService(2) or notReady(3) states only.
