Description: Manages Nortel Magellan Passport Frame Relay over ISDN B-channel interface configuration.

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 Nortel-Magellan-Passport-FrameRelayIsdnMIB?

This Nortel Magellan Passport MIB module manages Frame Relay service carried over ISDN B-channel interfaces (UNI signaling) on Passport wide-area switches. It exposes provisioning objects (row status, component naming, storage type) alongside protocol-specific parameters such as T320 timer values and address signalling mode, plus operational status objects for the Frame Relay/ISDN interface. Its monitoring value lies in confirming the provisioning and operational state of the Frame Relay-over-ISDN link — row status shows whether an interface is properly provisioned, and the operational table reflects whether the link is currently functioning, both software/protocol-state indicators of link health rather than physical sensors. It shares Nortel Magellan Passport's common component-naming and row-status conventions with the module's other signaling MIBs (such as the ISDN NIS MIB), indicating a dependency on that shared Passport MIB framework. It is deployed on legacy Nortel Magellan Passport WAN switches where Frame Relay services are backhauled over ISDN B-channels. Network engineers evaluating or troubleshooting this functionality can download the Nortel-Magellan-Passport-FrameRelayIsdnMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-FrameRelayIsdnMIB. 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 frUniIsdnRowStatusTable/frUniIsdnRowStatusEntry (indexed by frUniIsdnIndex) to confirm frUniIsdnRowStatus shows an interface as active, then check the frUniIsdnProvTable for frUniIsdnT320 timer settings and frUniIsdnAddressSignalling mode. The frUniIsdnOperTable would then be checked for actual operational state; a provisioned entry (active row status) that never transitions to an "up" operational state would point to a failed Frame Relay-over-ISDN link.

OIDs

OID symbolic	OID numeric	Type	Access	Description
frUniIsdn	1.3.6.1.4.1.562.2.4.1.71.100
frUniIsdnRowStatusTable	1.3.6.1.4.1.562.2.4.1.71.100.1		not-accessible	This entry controls the addition and deletion of frUniIsdn components.
frUniIsdnRowStatusEntry	1.3.6.1.4.1.562.2.4.1.71.100.1.1		not-accessible	A single entry in the table represents a single frUniIsdn component.
ROW frUniIsdnRowStatus	1.3.6.1.4.1.562.2.4.1.71.100.1.1.1	RowStatus	read-write	This variable is used as the basis for SNMP naming of frUniIsdn components. These components can be added and deleted.
STR frUniIsdnComponentName	1.3.6.1.4.1.562.2.4.1.71.100.1.1.2	DisplayString	read-only	This variable provides the component's string name for use with the ASCII Console Interface
STO frUniIsdnStorageType	1.3.6.1.4.1.562.2.4.1.71.100.1.1.4	StorageType	read-only	This variable represents the storage type value for the frUniIsdn tables.
NON frUniIsdnIndex	1.3.6.1.4.1.562.2.4.1.71.100.1.1.10	NonReplicated	not-accessible	This variable represents the index for the frUniIsdn tables.
frUniIsdnProvTable	1.3.6.1.4.1.562.2.4.1.71.100.11		not-accessible	This group contains the provisionable attributes of the Isdn component.
frUniIsdnProvEntry	1.3.6.1.4.1.562.2.4.1.71.100.11.1		not-accessible	An entry in the frUniIsdnProvTable.
U32 frUniIsdnT320	1.3.6.1.4.1.562.2.4.1.71.100.11.1.1	Unsigned32	read-write	This attribute specifies the waiting time for a silent B-Channel (no active VCs associated with the FrUni) to be disconnected and made available. Default is 60 seconds. 0 means t320 will never timeout.
INT frUniIsdnAddressSignalling	1.3.6.1.4.1.562.2.4.1.71.100.11.1.2	INTEGER	read-write	This attribute defines whether the ISDN Calling Party Number is to be signalled to the remote DTE during an SVC call establishment. Otherwise, no changes to the current behavior of SVC call establishement (i.e., Passport Dna is used in the calling party number information element).
frUniIsdnOperTable	1.3.6.1.4.1.562.2.4.1.71.100.12		not-accessible	This group contains the operational attributes of the Isdn component.
frUniIsdnOperEntry	1.3.6.1.4.1.562.2.4.1.71.100.12.1		not-accessible	An entry in the frUniIsdnOperTable.

INT frUniIsdnBChannelState	1.3.6.1.4.1.562.2.4.1.71.100.12.1.2	INTEGER	read-only	This attribute indicates the state of the B-Channel. If the value is idle it means that no VCs are connected and this B-Channel is available. If the value is busy it means this B-Channel has been allocated and is not available. If the value is disabled it means the application interface or the port is locked or disabled.
STR frUniIsdnLastUsedCgpn	1.3.6.1.4.1.562.2.4.1.71.100.12.1.3	DigitString	read-only	This attribute indicates the calling party number currently using the B-Channel. When the B-Channel is free, the null string is displayed.
INT frUniIsdnBChanIntState	1.3.6.1.4.1.562.2.4.1.71.100.12.1.4	INTEGER	read-only	Debug information
