What Is CXGwFr-MIB?

CXGwFr-MIB is a CX/Memotec MIB managing Frame Relay gateway services and protocol conversion functionality, letting a device bridge or convert between Frame Relay and other WAN protocols. Based on its naming and the one confirmed object, it exposes a gateway frame-relay-to-frame (gff) SAP table tracking per-channel gateway conversion configuration and state. For monitoring it would be used to confirm each gateway SAP/channel is operationally active and correctly converting protocol frames, revealing a channel that has failed to establish its Frame Relay conversion path rather than any physical hardware fault. It depends on underlying Frame Relay standards (ANSI/ITU Frame Relay, and the base FRAME-RELAY-DTE-MIB concepts) for the DLCI/circuit layer being gatewayed. It is deployed on CX Memotec WAN gateway devices performing Frame Relay protocol conversion/interworking. Engineers can download the CXGwFr-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CXGwFr-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

An administrator would poll gffSapTable/gffSapEntry (inferred per-SAP entry of the gateway frame-relay-to-frame table) for per-channel status to confirm a given gateway conversion path is operationally established. Since only gffSapTable was confirmed among sample_objects, more granular per-column details (e.g., specific status or counter columns) are not confirmed and would need to be verified against the actual MIB source rather than assumed. A channel showing an inactive or error state in this table would indicate a Frame Relay gateway conversion failure needing investigation.

OBJECT-TYPE

OIDs

OID symbolic	OID numeric	Type	Access	Description
gffSapTable	1.3.6.1.4.1.495.2.1.6.18.1		not-accessible	Table containing configuration information about all the GFF module SAPs.
gffSapEntry	1.3.6.1.4.1.495.2.1.6.18.1.1		not-accessible	This row holds all the parameters related to a particular GFF module SAP.
SAP gffSapId	1.3.6.1.4.1.495.2.1.6.18.1.1.1	SapIndex	read-only	Identifies the SAP by a unique numerical value.
INT gffSapRowStatus	1.3.6.1.4.1.495.2.1.6.18.1.1.2	INTEGER	read-write	This parameter is relevant to upper SAPs only. Indicates whether this SAP is configured in the CE. Options: invalid (1): Deletes the current entry (row) in the table. valid (2): Creates a SAP entry (row) in the table. Default Value: valid (2) Related Objects: gffSapType Configuration Changed: administrative
INT gffSapType	1.3.6.1.4.1.495.2.1.6.18.1.1.3	INTEGER	read-write	Identifies the SAP type. There is one lower SAP connected permanently to TBC and up to 16 upper SAPs connected to FRM. Options: lower (1): SAP is a lower type (leads to the bus of the CX1000 chassis) upper (2): SAP is an upper type (leads to a lower SAP in the Frame Relay software layer) Default Value: none Configuration Changed: administrative
ALI gffSapAlias	1.3.6.1.4.1.495.2.1.6.18.1.1.4	Alias	read-write	Identifies the GFF local SAP by a textual name. Range of Values: 0 to 35 alphanumeric characters beginning with a non-numeric character. Default Value: gffsap1 (for gffSapId 1) gffsap2 (for gffSapId 2) gffsap3 (for gffSapId 3) gffsap4 (for gffSapId 4) gffsap5 (for gffSapId 5) gffsap6 (for gffSapId 6) gffsap7 (for gffSapId 7) gffsap8 (for gffSapId 8) gffsap9 (for gffSapId 9) gffsap10 (for gffSapId 10) gffsap11 (for gffSapId 11) gffsap12 (for gffSapId 12) gffsap13 (for gffSapId 13) gffsap14 (for gffSapId 14) gffsap15 (for gffSapId 15) gffsap16 (for gffSapId 16) gffsap17 (for gffSapId 17) Configuration Changed: administrative

INT gffSapAssociatedSlotNo	1.3.6.1.4.1.495.2.1.6.18.1.1.6	INTEGER	read-write	This parameter is relevant to upper SAPs only. Identifies the local chassis slot number that communicates with the Frame Relay service through this SAP. Range of Values: 1 - 16 Default Value: 6 Related Objects: gffSapType Configuration Changed: administrative
INT gffSapWindowWidth	1.3.6.1.4.1.495.2.1.6.18.1.1.7	INTEGER	read-write	This object is relevant to upper SAPs only and concerns the traffic going from FRM to GFF.

Range of Values: 40 - 100 Default Value: 40 Related Objects: gffSapType Configuration Changed: administrative
INT gffSapTrafficPriority	1.3.6.1.4.1.495.2.1.6.18.1.1.8	INTEGER	read-write	Determines the priority for sending frames to a PX600 card or to the Frame Relay software layer. Options: 1: urgent 2: expeditious 3: normal Default Value: 3 Configuration Changed: operative, but only if this object's row was included in the table at the last system reset. Otherwise, change is administrative.
INT gffSapMaxFrameSize	1.3.6.1.4.1.495.2.1.6.18.1.1.9	INTEGER	read-write	Determines the maximum frame size the Frame Relay software layer can expect from the GFF module. Range of Values: 3 - 8192 (bytes) Default Value: 4096 Configuration Changed: operative, but only if this object's row was included in the table at the last system reset.
