Description: Manages pseudowire emulation edge-to-edge (PWE3) connections over MPLS and IP transport networks.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring CISCO-IETF-PW-MIB with a free 30-day trial of IPNetwork Monitor.

What Is CISCO-IETF-PW-MIB?

CISCO-IETF-PW-MIB is a Cisco implementation of the IETF pseudowire emulation edge-to-edge (PWE3) draft standard, part of the MPLS/carrier-Ethernet transport technology area. It defines managed objects for configuring and monitoring pseudowire connections that emulate a Layer 2 circuit over an MPLS or IP packet-switched network, including PW type, encapsulation, and state. Because pseudowires are software-defined transport constructs, this module is primarily about monitoring software/service status rather than physical hardware: PW operational/administrative state, up/down transitions, and VC-type-specific parameters that reveal service faults. It has an explicit dependency, deferring VC-type-specific detail to companion PSN-specific and VC-specific MIBs (e.g. per the referenced pwe3-framework and l2circuit-trans-mpls drafts) that share its index structure. It is typically deployed on Cisco provider-edge routers delivering Layer 2 VPN / pseudowire services across an MPLS core, where engineers load the CISCO-IETF-PW-MIB module into their network management system to track pseudowire health alongside the companion PSN- and VC-specific MIBs.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-IETF-PW-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

Cisco ASR 9001 — compact chassis in the ASR 9000 series, current flagship MPLS/pseudowire provider-edge router

Monitoring Examples

No sample runtime objects were provided for this module in the supplied data, so a concrete polling scenario cannot be grounded in real object names here; in general use an operator would monitor per-pseudowire administrative/operational status and VC-type-specific counters to detect a pseudowire that has gone down or is flapping between PSN and attachment circuit, using the shared index into the PSN-specific and VC-specific tables described in the module.

What Can Be Monitored

pseudowire operational state
pseudowire administrative state

How to Use in IPNetwork Monitor

Example using cpwVcTimeElapsed OID:

Select a Cisco ASR 9001 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 cpwVcTimeElapsed 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. It reports how many seconds have elapsed in the pseudowire's current 15-minute performance-measurement interval. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the value is stuck at the same number across repeated polls — since it normally cycles from 1 to 900 every 15 minutes by design, a stalled value indicates the pseudowire has stopped collecting statistics. Click Finish to create the monitor; you can adjust any parameter later.

T/F cpwVcControlWord	1.3.6.1.4.1.9.10.106.1.2.1.12	TruthValue	read-create	Define if the control word will be sent with each packet by the local node.
TIM cpwVcCreateTime	1.3.6.1.4.1.9.10.106.1.2.1.23	TimeStamp	read-only	System time when this VC was created.
STR cpwVcDescr	1.3.6.1.4.1.9.10.106.1.2.1.22	SnmpAdminString	read-create	A textual string containing information about the VC. If there is no description this object contains a zero length string.
NTF cpwVcDown	1.3.6.1.4.1.9.10.106.2.1			This notification is generated when the cpwVcOperStatus object for one or more contiguous entries in cpwVcTable are about to enter the down(2) state from some other state. The included values of cpwVcOperStatus MUST all be set equal to this down(2) state. The two instances of cpwVcOperStatus in this notification indicate the range of indexes that are affected. Note that all the indexes of the two ends of the range can be derived from the instance identifiers of these two objects. For cases where a contiguous range of cross-connects have transitioned into the down(2) state at roughly the same time, the device SHOULD issue a single notification for each range of contiguous indexes in an effort to minimize the emission of a large number of notifications. If a notification has to be issued for just a single cross-connect entry, then the instance identifier (and values) of the two cpwVcOperStatus objects MUST be identical.
cpwVcEntry	1.3.6.1.4.1.9.10.106.1.2.1		not-accessible	A row in this table represents an emulated virtual connection (VC) across a packet network. It is indexed by cpwVcIndex, which uniquely identifying a singular connection.
cpwVcGroup	1.3.6.1.4.1.9.10.106.3.1.1			Collection of objects needed for PW VC configuration.
cpwVcGroups	1.3.6.1.4.1.9.10.106.3.1

VCs with the same priority are treated with equal priority. Dropped VC will be set 'dormant' (as indicated in cpwVcOperStatus). This value is significant if there are competing resources between VCs and the implementation support this feature. If not supported or not relevant, the value of zero MUST be used.
CPW cpwVcID	1.3.6.1.4.1.9.10.106.1.2.1.10	CpwVcIDType	read-create	Used in the outgoing VC ID field within the 'Virtual Circuit FEC Element' when LDP signaling is used or PW ID AVP for L2TP.

CPW cpwVcIdMappingVcType	1.3.6.1.4.1.9.10.106.1.7.1.1	CpwVcType	not-accessible	The VC type (indicate the service) of this VC.
INT cpwVcInboundMode	1.3.6.1.4.1.9.10.106.1.2.1.7	INTEGER	read-create	This object is used to enable greater security for implementation that use per platform VC label space. In strict mode, packets coming from the PSN are accepted only from tunnels that are associated to the same VC via the inbound tunnel table in the case of MPLS, or as identified by the source IP address in case of L2TP or IP PSN. The entries in the inbound tunnel table are either explicitly configured or implicitly known by the maintenance protocol used for VC set-up. If such association is not known, not configured or not desired, loose mode should be configured, and the node should accept the packet based on the VC label only regardless of the outer tunnel used to carry the VC.
CPW cpwVcInboundOperStatus	1.3.6.1.4.1.9.10.106.1.2.1.27	CpwOperStatus	read-only	Indicates the actual operational status of this VC in the inbound direction. - down: if PW signaling has not yet finished, or indications available at the service level indicate that the VC is not passing packets. - testing: if AdminStatus at the VC level is set to test. - dormant: The VC is not available because of the required resources are occupied VC with higher priority VCs . - notPresent: Some component is missing to accomplish the set up of the VC. - lowerLayerDown: The underlying PSN is not in OperStatus 'up'.
U32 cpwVcInboundVcLabel	1.3.6.1.4.1.9.10.106.1.2.1.20	Unsigned32	read-create	The VC label used in the inbound direction (i.e. packets received from the PSN. It may be set up manually if owner is 'manual' or automatically otherwise. Examples: For MPLS PSN, it represents the 20 bits of VC tag, for L2TP it represent the 32 bits Session ID. If the label is not yet known (signaling in process), the object should return a value of 0xFFFF.
CPW cpwVcIndex	1.3.6.1.4.1.9.10.106.1.2.1.1	CpwVcIndexType	not-accessible	Index for the conceptual row identifying a VC within this PW Emulation VC table.
U32 cpwVcIndexNext	1.3.6.1.4.1.9.10.106.1.1	Unsigned32	read-only	This object contains an appropriate value to be used for cpwVcIndex when creating entries in the cpwVcTable. The value 0 indicates that no unassigned entries are available. To obtain the value of cpwVcIndex for a new entry in the cpwVcTable, the manager issues a management protocol retrieval operation to obtain the current value of cpwVcIndex. 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.
CPW cpwVcLocalGroupID	1.3.6.1.4.1.9.10.106.1.2.1.11	CpwGroupID	read-create	Used in the Group ID field sent to the peer PWES within the maintenance protocol used for VC setup, zero if not used.

T/F cpwVcLocalIfString	1.3.6.1.4.1.9.10.106.1.2.1.14	TruthValue	read-create	Each VC is associated to an interface (or a virtual interface) in the ifTable of the node as part of the service configuration. This object defines if the maintenance protocol will send the interface's name as appears on the ifTable in the name object as part of the maintenance protocol. If set to false, the optional element will not be sent.
cpwVcMappingTablesGroup	1.3.6.1.4.1.9.10.106.3.1.3			Collection of objects contained in the reverse mapping tables.
cpwVcMIB	1.3.6.1.4.1.9.10.106			This MIB contains managed object definitions for Pseudo Wire operation as in: Pate, P., et al, , Xiao, X., et al, , Martini, L., et al, , and Martini, L., et al, . The indexes for this MIB are also used to index the PSN- specific tables and the VC-specific tables. The VC Type dictates which VC-specific MIB to use. For example, a 'cep' VC Type requires the use the configuration and status tables within the CEP-MIB. This MIB enable the use of any underlying packet switched network (PSN). Specific tables for the MPLS PSN is currently defined in a separate CISCO-IETF-PW-MPLS-MIB. Tables to support other PSNs (IP, L2TP for example) will be added to this MIB in future revisions. At the time of publication of this version, there are no PWE3 WG documents for all features and objects in this MIB, and the MIB is therefore subject to change based on the WG progress.
STR cpwVcName	1.3.6.1.4.1.9.10.106.1.2.1.21	SnmpAdminString	read-create	The canonical name assigned to the VC.

cpwVcObjects	1.3.6.1.4.1.9.10.106.1
CPW cpwVcOperStatus	1.3.6.1.4.1.9.10.106.1.2.1.26	CpwOperStatus	read-only	Indicates the actual combined operational status of this VC. It is 'up' if both cpwVcInboundOperStatus and cpwVcOutboundOperStatus are in 'up' state. For all other values, if the VCs in both directions are of the same value it reflects that value, otherwise it is set to the most severe status out of the two statuses. The order of severance from most severe to less severe is: unknown, notPresent, down, lowerLayerDown, dormant, testing, up. The operator may consult the per direction OperStatus for fault isolation per direction.
CPW cpwVcOutboundOperStatus	1.3.6.1.4.1.9.10.106.1.2.1.28	CpwOperStatus	read-only	Indicates the actual operational status of this VC in the outbound direction - down: if PW signaling has not yet finished, or indications available at the service level indicate that the VC is not passing packets. - testing: if AdminStatus at the VC level is set to test. - dormant: The VC is not available because of the required resources are occupied VC with higher priority VCs . - notPresent: Some component is missing to accomplish the set up of the VC. - lowerLayerDown: The underlying PSN is not in OperStatus 'up'.

It may be set up manually if owner is 'manual' or automatically otherwise. Examples: For MPLS PSN, it represents the 20 bits of VC tag, for L2TP it represent the 32 bits Session ID. If the label is not yet known (signaling in process), the object should return a value of 0xFFFF.
INT cpwVcOwner	1.3.6.1.4.1.9.10.106.1.2.1.3	INTEGER	read-create	Set by the operator to indicate the protocol responsible for establishing this VC. Value 'manual' is used in all cases where no maintenance protocol (PW signaling) is used to set-up the VC, i.e. require configuration of entries in the VC tables including VC labels, etc. The value 'maintenanceProtocol' is used in case of standard signaling of the VC for the specific PSN, for example LDP for MPLS PSN as specified in or L2TP control protocol. Value 'other' is used for other types of signaling.
IP cpwVcPeerAddr	1.3.6.1.4.1.9.10.106.1.2.1.9	InetAddress	read-create	This object contains the value of of the peer node address of the PW/PE maintenance protocol entity. This object should contain a value of 0 if not relevant (manual configuration of the VC).

NTF cpwVcUp	1.3.6.1.4.1.9.10.106.2.2			This notification is generated when the cpwVcOperStatus object for one or more contiguous entries in cpwVcTable are about to enter the up(1) state from some other state. The included values of cpwVcOperStatus MUST both be set equal to this new state (i.e: up(1)). The two instances of cpwVcOperStatus in this notification indicate the range of indexes that are affected. Note that all the indexes of the two ends of the range can be derived from the instance identifiers of these two objects. For cases where a contiguous range of cross-connects have transitioned into the up(1) state at roughly the same time, the device SHOULD issue a single notification for each range of contiguous indexes in an effort to minimize the emission of a large number of notifications. If a notification has to be issued for just a single cross-connect entry, then the instance identifier (and values) of the two cpwVcOperStatus objects MUST be the identical.
T/F cpwVcUpDownNotifEnable	1.3.6.1.4.1.9.10.106.1.9	TruthValue	read-write	If this object is set to true(1), then it enables the emission of cpwVcUp and cpwVcDown notifications; otherwise these notifications are not emitted.
TIK cpwVcUpTimeEx	1.3.6.1.4.1.9.10.106.1.2.1.24	TimeTicks	read-only	Number of consecutive ticks this VC has been 'up' in both directions together (i.e. 'up' is observed in cpwVcOperStatus.)
I32 cpwVcValidIntervals	1.3.6.1.4.1.9.10.106.1.2.1.30	Integer32	read-only	The number of previous 15-minute intervals for which data was collected. An agent with PW capability must be capable of supporting at least n intervals. The minimum value of n is 4, The default of n is 32 and the maximum value of n is 96. The value will be unless the measurement was (re-) started within the last (*15) minutes, in which case the value will be the number of complete 15 minute intervals for which the agent has at least some data. In certain cases (e.g., in the case where the agent is a proxy) it is possible that some intervals are unavailable. In this case, this interval is the maximum interval number for which data is available.
