Description: Configures and monitors reconfigurable optical add-drop multiplexer channel routing on NBS ROADM devices.

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-ROADM-MIB?

NBS-ROADM-MIB is an enterprise MIB (NBS/Nortel optical products) for configuring and monitoring Reconfigurable Optical Add/Drop Multiplexer (ROADM) channel routing in DWDM optical transport networks. It exposes configuration and status data organized per optical interface, including staging tables for add/drop capabilities, quick-configuration commit operations, committed grid type, committed channel assignments, and flexgrid-specific channel tables. Its monitoring emphasis is on the operational/software state of the optical add-drop function -- confirming which wavelength channels are committed and routed on a given interface, whether staged configuration changes have been committed, and whether the grid type (fixed vs. flexgrid) matches the intended design -- serving as a health/status check for the optical routing layer rather than a general hardware sensor MIB. It is a self-contained optical-transport enterprise MIB, though it operates in the broader context of ITU-T G.694 flexible/fixed grid standards for DWDM. It is deployed on NBS/Nortel ROADM network elements in metro/long-haul DWDM optical transport networks. Engineers can download the NBS-ROADM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in NBS-ROADM-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 operator would poll nbsRoadmCommonTable/nbsRoadmCommonEntry, checking nbsRoadmCommonCommittedGridType and nbsRoadmCommonCommittedChannels against nbsRoadmCommonIfIndex to confirm a given optical port has the expected wavelength channels committed and routed. Checking nbsRoadmCommonStagingCommit would reveal whether a pending add/drop configuration change was successfully applied, while nbsRoadmFlexgridTable/nbsRoadmFlexgridTableSize would be checked on flexgrid-capable ports to verify flexible channel spacing is correctly provisioned. A mismatch between staged add/drop capabilities and the committed channel list would indicate a failed or incomplete ROADM reconfiguration.

What Can Be Monitored

committed grid type
committed wavelength channels
staged add/drop capabilities
configuration commit status
flexgrid channel table size

OID symbolic	OID numeric	Type	Access	Description
nbsRoadmMib	1.3.6.1.4.1.629.235			Reconfigurable Optical Add/Drop Multiplexing
nbsRoadmCommonGrp	1.3.6.1.4.1.629.235.10			Channels per Common port
U32 nbsRoadmCommonTableSize	1.3.6.1.4.1.629.235.10.1	Unsigned32	read-only	The number of entries in nbsRoadmCommonTable
nbsRoadmCommonTable	1.3.6.1.4.1.629.235.10.2		not-accessible	WSS Switch Configuration
nbsRoadmCommonEntry	1.3.6.1.4.1.629.235.10.2.1		not-accessible
NUM nbsRoadmCommonIfIndex	1.3.6.1.4.1.629.235.10.2.1.1	InterfaceIndex	read-only	The Mib2 ifIndex of this channel's trunk port.
INT nbsRoadmCommonStagingQuickCfg	1.3.6.1.4.1.629.235.10.2.1.10	INTEGER	read-write	Impulse object used to replace this port's current nbsRoadmStagingTable entries with a known configuration. Users may create the nbsRoadmStagingTable manually, a row at a time. Often it would save the users much work if they could initially populate this table with a standard or known configuration and then customize it to their own requirements. When read, this object will indicate whether this feature is available by reporting either notSupported(1) or supported(2). The value std100Ghz(3) overwrites this port's nbsRoadmStagingTable with all the standard 100 GHz ITU grid channels which are supported by this port. The value std50Ghz(4) overwrites this port's nbsRoadmStagingTable with all the standard 50 GHz ITU grid channels which are supported by this port. Overwriting the nbsRoadmStagingTable entries has no effect on the live configuration until committed using nbsRoadmCommonStagingCommit
INT nbsRoadmCommonStagingAddCaps	1.3.6.1.4.1.629.235.10.2.1.13	INTEGER	read-only	This object indicates if this port is capable of Add
INT nbsRoadmCommonStagingDropCaps	1.3.6.1.4.1.629.235.10.2.1.14	INTEGER	read-only	This object indicates if this port is capable of Drop
NBS nbsRoadmCommonStagingCommit	1.3.6.1.4.1.629.235.10.2.1.20	NbsTcStagingCommit	read-write	Impulse object used to rewrite the entire WSS configuration. In order to protect users against accidentally dropping traffic streams, a two-step process is used. In the first step, users 'stage' a WSS configuration. The nbsRoadmStagingTable is like a scratchpad where users can build and modify the entire WSS configuration without affecting the live network. Here users assign channels to WSS ports, and for flex-grids, define the channels. The second step is to replace the existing WSS configuration (which can be read from the nbsRoadmCommittedTable). To replace the existing setup with the configuration specified in the nbsRoadmStagingTable, users set this object to apply(4). To discard all changes done to nbsRoadmStagingTable, users set this object to revertToCommitted(3), which will synchronize the Staging table to the Staged configuation. When read, this object will report the action last requested until that action is completed, after which it will report supported(2).
INT nbsRoadmCommonCommittedGridType	1.3.6.1.4.1.629.235.10.2.1.30	INTEGER	read-only	This object is automatically updated in association with writes to nbsRoadmCommonStagingApply. It indicates whether or not this port's updated nbsRoadmCommittedTable is equivalent to a standard ITU grid such as would come from nbsRoadmCommonStagingQuickCfg. If the nbsRoadmCommittedTable matches the results from a nbsRoadmCommonStagingQuickCfg of std100Ghz(4), then this object will report std100Ghz(4). If the nbsRoadmCommittedTable matches the results from a nbsRoadmCommonStagingQuickCfg of std50Ghz(5), then this object will report std50Ghz(5). If the nbsRoadmCommittedTable matches neither the results from a nbsRoadmCommonStagingQuickCfg of std100Ghz(4) or std50Ghz(5), then this object will report customized(3).
INT nbsRoadmCommonCommittedChannels	1.3.6.1.4.1.629.235.10.2.1.40	INTEGER	read-only	The number of channels for this wdm port in the nbsRoadmCommittedTable.

NBS nbsRoadmFlexgridCenterlineMax	1.3.6.1.4.1.629.235.20.2.1.22	NbsTcMHz	read-only	The frequency of the highest centerline possible.
NBS nbsRoadmFlexgridCenterlineIncr	1.3.6.1.4.1.629.235.20.2.1.23	NbsTcMHz	read-only	Centerline increment - the minimum possible difference, in MHz, between adjacent channels' centerlines.
NBS nbsRoadmFlexgridBandwidthMin	1.3.6.1.4.1.629.235.20.2.1.31	NbsTcMHz	read-only	The minimum bandwidth possible. Each channel must be at least this wide.
NBS nbsRoadmFlexgridBandwidthMax	1.3.6.1.4.1.629.235.20.2.1.32	NbsTcMHz	read-only	The maximum bandwidth possible. Each channel must be at most this wide.
NBS nbsRoadmFlexgridBandwidthIncr	1.3.6.1.4.1.629.235.20.2.1.33	NbsTcMHz	read-only	The granularity of bandwidths possible. Each channel's bandwidth must be a multiple of this number.
