Description: Manages tunable laser and wavelength selection parameters for NBS tunable optical transceivers.

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 NBS-TUNABLE-MIB?

NBS-TUNABLE-MIB is an NBS (built on NBS-CMMC-MIB) proprietary MIB reporting tunable-optics parameters for DWDM transponders. Its channel table, keyed by ifIndex, records channel-table size, frequency start/end/step/exponent, and administrative/operational/default frequency. As a configuration/status MIB it lets an administrator confirm the tuned wavelength/frequency of a tunable optical transponder on an NBS DWDM platform. It is deployed on NBS DWDM transport equipment (tunable optics). Engineers can download the NBS-TUNABLE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NBS-TUNABLE-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

NBS DWDM transport equipment (tunable optics)

Monitoring Examples

An administrator checks nbsTunableChannelFreqOper to confirm the currently tuned frequency of a DWDM transponder on an NBS platform.

OIDs

OID symbolic	OID numeric	Type	Access	Description
nbsTunableMib	1.3.6.1.4.1.629.203			MIB for representing Tunable Optics parameters
nbsTunableGrp	1.3.6.1.4.1.629.203.1			MIB for representing Tunable Optics parameters
U32 nbsTunableChannelTableSize	1.3.6.1.4.1.629.203.1.1	Unsigned32	read-only	The number of entries in nbsTunableChannelTable.
nbsTunableChannelTable	1.3.6.1.4.1.629.203.1.2		not-accessible	A table to report and configure tunable optics settings.
nbsTunableChannelEntry	1.3.6.1.4.1.629.203.1.2.1		not-accessible	Describes a setting for an interface's tunable optics.
NUM nbsTunableChannelIfIndex	1.3.6.1.4.1.629.203.1.2.1.1	InterfaceIndex	read-only	The Mib2 ifIndex of this optic's port
INT nbsTunableChannelFreqStart	1.3.6.1.4.1.629.203.1.2.1.2	INTEGER	read-only	The first allowable frequency for this tunable optic, in GigaHertz (GHz), unless FreqExponent != 9. For L-Band, ITU Grid 48 is '184800' For Q-Band, ITU Grid 48 is '184850' For C-Band, ITU Grid 1 is '190100' For H-Band, ITU Grid 1 is '190150' If GHz does not provide the appropriate resolution, the tunable optic may report a FreqExponent less than 9. If 32 bits is insufficient to cover the range in GHz, the tunable optic may report a FreqExponent greater than 9.
INT nbsTunableChannelFreqEnd	1.3.6.1.4.1.629.203.1.2.1.3	INTEGER	read-only	The last allowable frequency (inclusive) for this tunable optic, in GigaHertz (GHz), unless FreqExponent != 9. For L-Band, ITU Grid 99 is '189900' For Q-Band, ITU Grid 99 is '189950' For C-Band, ITU Grid 72 is '197200' For H-Band, ITU Grid 72 is '197250' If GHz does not provide the appropriate resolution, the tunable optic may report a FreqExponent less than 9. If 32 bits is insufficient to cover the range in GHz, the tunable optic may report a FreqExponent greater than 9.
INT nbsTunableChannelFreqStep	1.3.6.1.4.1.629.203.1.2.1.4	INTEGER	read-only	The spacing of the allowable frequencies that this tunable optic supports, in GigaHertz (GHz), unless FreqExponent != 9. 100 indicates the standard ITU grid spacing of 100GHz. For example, if this tunable optic supports both C and H band, or both Q and L band, FreqStep should report 50. If this tunable optic supports steps finer than 1GHz, the tunable optic may report a FreqExponent less than 9.
INT nbsTunableChannelFreqExponent	1.3.6.1.4.1.629.203.1.2.1.5	INTEGER	read-only	The exponent of all the Freq values (including FreqStep). 9 (the default) indicates all units are in GigaHertz (GHz).
INT nbsTunableChannelFreqAdmin	1.3.6.1.4.1.629.203.1.2.1.6	INTEGER	read-write	The administratively desired frequency of this tunable optic, in GigaHertz (GHz), unless FreqExponent != 9.
INT nbsTunableChannelFreqOper	1.3.6.1.4.1.629.203.1.2.1.7	INTEGER	read-only	The current operational frequency of this tunable optic, in GigaHertz (GHz), unless FreqExponent != 9.
INT nbsTunableChannelFreqDefault	1.3.6.1.4.1.629.203.1.2.1.8	INTEGER	read-only	The default frequency of this tunable optic, in GigaHertz (GHz), unless FreqExponent != 9.
