Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCO-IETF-PW-FR-MIB?

CISCO-IETF-PW-FR-MIB is a Cisco vendor MIB (registered under ciscoExperiment, based on the IETF PWE3 Frame Relay over Pseudowire draft) that manages Frame Relay pseudowire emulation over a packet-switched network. It exposes cpwVcFrTable for one-to-one FR-VC-to-PW mappings (cpwVcFrIfIndex, cpwVcFrDlci, cpwVcFrAdminStatus, cpwVcFrOperStatus, cpwVcFrRowStatus) and cpwVcFrPMTable for port-mode mappings where all DLCIs on a port share a single PW. Each entry correlates to the corresponding row in the generic Pseudowire MIB's VC table via a shared index, so this MIB layers Frame Relay-specific status (cpwVcFrPw2FrOperStatus, the FR-segment operational state) on top of the base PW connection state. It depends on CISCO-IETF-PW-TC-MIB, IF-MIB, and CISCO-FRAME-RELAY-MIB for shared types and is deployed on Cisco routers acting as Frame Relay/PW gateways carrying legacy FR traffic over MPLS or IP PSNs. Network engineers rely on the CISCO-IETF-PW-FR-MIB MIB to confirm whether a given DLCI's pseudowire emulation is administratively up and operationally active end to end.

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

Cisco routers/switches supporting Frame Relay over Pseudowire (FRoPW) emulation

Monitoring Examples

An operator polls cpwVcFrTable (indexed by cpwVcFrPwVcIndex) to check cpwVcFrDlci against cpwVcFrAdminStatus and cpwVcFrOperStatus; cpwVcFrOperStatus reporting inactive while cpwVcFrAdminStatus is up(1) would indicate the Frame Relay segment or the underlying pseudowire has failed, breaking end-to-end FR service for that DLCI.

What Can Be Monitored

FR VC to pseudowire connection mappings
DLCI administrative and operational status
FR-segment vs. PW-segment operational state
port-mode (many-to-one) pseudowire mappings
row status/storage type of PW-FR entries

OIDs

OID symbolic	OID numeric	Type	Access	Description
cpwVcFrMIB	1.3.6.1.4.1.9.10.112			Cisco Pseudo Wire Frame Relay MIB This MIB describes network management objects defined for FRoPW services over a Packet Switched Network (PSN). As described in the IETF Frame Relay over Pseudowire (FRoPW) draft, draft-ietf-pwe3-frame-relay-01.txt, FR VCs and PW can be mapped in 2 modes: One-to-one mapping mode: a FR VC is mapped to a PW. This mode is described by cpwVcFrTable. Many-to-one mapping mode (a.k.a. port mode): multiple FR VCs assigned to a port are mapped to a PW. This mode is addressed by cpwVcFrPortModeTable. In this mode, all data frames are directed to the associated PSN tunnel regardless of DLCI.
cpwVcFrNotifications	1.3.6.1.4.1.9.10.112.0
cpwVcFrObjects	1.3.6.1.4.1.9.10.112.1
cpwVcFrTable	1.3.6.1.4.1.9.10.112.1.1		not-accessible	The PW-FR connection table. Each entry in this table represents a FRoPW connection operating in one-to-one mapping mode. This table uses the same index as the generic PW MIB's VC table. Therefore, each entry in cpwVcFrTable has a mapping entry to the generic PW MIB VC table associated by the PW VC index. An entry is created in this table by the agent for every entry in the generic PW MIB VC table with a VcType of 'frameRelay'.
cpwVcFrEntry	1.3.6.1.4.1.9.10.112.1.1.1		not-accessible	An entry in cpwVcFrTable.
CPW cpwVcFrPwVcIndex	1.3.6.1.4.1.9.10.112.1.1.1.1	CpwVcIndexType	not-accessible	This object identifies the index to an entry in the generic PW table.
NUM cpwVcFrIfIndex	1.3.6.1.4.1.9.10.112.1.1.1.2	InterfaceIndexOrZero	read-create	This object identifies the index to an entry in the IF-MIB table. In this case, it holds the ifIndex value of the Frame Relay interface associating with the PW connection. The value of zero means that the InterfaceIndex is not known yet.
DLC cpwVcFrDlci	1.3.6.1.4.1.9.10.112.1.1.1.3	DlciNumber	read-create	This object identifies the FR DLCI associating with this entry in cpwVcFrTable. This object can be used together with cpwVcFrIfIndex to lookup FR VC specific information for the FR PVC segment of a FRoPW connection.
INT cpwVcFrAdminStatus	1.3.6.1.4.1.9.10.112.1.1.1.4	INTEGER	read-create	This value of this object indicates the administrative status of the FRoPW connection. The values mean: up(1) - connection is administratively set to the 'up' state for handling traffic. down(2) - connection is administratively set to the 'down' state. No traffic is processed at this state.
INT cpwVcFrOperStatus	1.3.6.1.4.1.9.10.112.1.1.1.5	INTEGER	read-only	This is actual operational status of the logical FRoPW connection, which is derived from combining the following 2 operational status: cpwVcFrPw2FrOperStatus Operational status of the FR segment on the FRoPW connection. PW Operation Status Operational status of the PW segment of the FRoPW connection. The associated object is cpwVcOperStatus from the generic PW MIB.
INT cpwVcFrPw2FrOperStatus	1.3.6.1.4.1.9.10.112.1.1.1.6	INTEGER	read-only	The value of the object identifies the current operational status of the FR PVC segment of a FRoPW connection. The values mean: active(1) - segment is currently operational. inactive(2) - segment in currently not operational. unknown(3) - segment current status cannot be determined.
ROW cpwVcFrRowStatus	1.3.6.1.4.1.9.10.112.1.1.1.7	RowStatus	read-create	For creating, modifying, and deleting this row.
STO cpwVcFrStorageType	1.3.6.1.4.1.9.10.112.1.1.1.8	StorageType	read-create	Indicates the storage type of this row.
cpwVcFrPMTable	1.3.6.1.4.1.9.10.112.1.2		not-accessible	The PW-FR port mode connection table. Each entry in this table represents a FRoPW connection operating in the port mode. This table uses the same index as the generic PW MIB's VC table. Therefore, each entry in cpwVcFrTable has a mapping entry to the generic PW MIB VC table associated by the PW VC index. An entry is created in this table by the agent for every entry in the generic PW MIB VC table with a VcType of 'frameRelayPortMode'.
cpwVcFrPMEntry	1.3.6.1.4.1.9.10.112.1.2.1		not-accessible	An entry in cpwVcFrPMTable.
CPW cpwVcFrPMPwVcIndex	1.3.6.1.4.1.9.10.112.1.2.1.1	CpwVcIndexType	not-accessible	This object identifies the index to an entry in the generic PW table.
NUM cpwVcFrPMIfIndex	1.3.6.1.4.1.9.10.112.1.2.1.2	InterfaceIndexOrZero	read-create	This object represents the FR port associating with the FRoPW connection operating in port mode. The value in the index identifies an entry in the IF-MIB table. The value of zero means that the InterfaceIndex is not known yet.
INT cpwVcFrPMAdminStatus	1.3.6.1.4.1.9.10.112.1.2.1.3	INTEGER	read-create	This value of this object indicates the administrative status of the FRoPW connection. The values mean: up(1) - connection is administratively set to the 'up' state for handling traffic. down(2) - connection is administratively set to the 'down' state. No traffic is processed at this state.
INT cpwVcFrPMOperStatus	1.3.6.1.4.1.9.10.112.1.2.1.4	INTEGER	read-only	This is actual operational status of the logical FRoPW connection in port mode, which is derived from combining the following 2 operational status: cpwVcFrPMPw2FrOperStatus Operational status of the FR segment on the FRoPW connection. PW Operation Status Operational status of the PW segment of the FRoPW connection. The associated object is cpwVcOperStatus from the generic PW MIB.
INT cpwVcFrPMPw2FrOperStatus	1.3.6.1.4.1.9.10.112.1.2.1.5	INTEGER	read-only	The value of the object identifies the current operational status of the associate FR port. The values mean: active(1) - segment is currently operational. inactive(2) - segment in currently not operational. unknown(3) - segment current status cannot be determined.
