Description: TIMETRA-SAS-QOS-MIB module

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 TIMETRA-SAS-QOS-MIB?

TIMETRA-SAS-QOS-MIB is part of Alcatel-Lucent's (now Nokia) TiMOS MIB family, providing Quality of Service management specifically for the SAS (Service Access Switch) variants of the Alcatel 7x50 platform, covering MPLS EXP-bit profile mapping and access/egress QoS policy objects. It exposes configuration data for mapping MPLS LSP EXP bits to QoS profiles, defining EXP profile tables, and managing access-egress QoS objects, which govern how traffic is classified and scheduled across the device. Its monitoring value is primarily around configuration/software state: operators verify that MPLS EXP-to-QoS profile mappings (tMplsLspExpProfMapTable) and EXP profile definitions (tMplsLspExpProfileTable) are correctly provisioned and unchanged, since a misconfigured mapping can cause traffic to receive the wrong forwarding treatment. Each TIMETRA-SAS-QOS-MIB OID within these tables corresponds to a specific EXP-bit-to-profile mapping or profile definition that operators check against the intended QoS policy. It depends heavily on the broader TIMETRA MIB family (chassis, VRTR, and related QoS modules) and on standard MPLS DiffServ/EXP-bit conventions for its semantics. It is deployed on Alcatel-Lucent/Nokia 7x50 SAS platforms used by service providers needing MPLS-aware QoS at the network access edge.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-SAS-QOS-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

  • Nokia/Alcatel-Lucent 7210 SAS service access switch product line, entire range (MPLS EXP-to-QoS profile mapping status)

Monitoring Examples

An operator would walk tMplsLspExpProfMapTable/tMplsLspExpProfMapEntry indexed by tMplsLspExpProfMapIndex to confirm each EXP-to-profile mapping's tMplsLspExpProfMapRowStatus and tMplsLspExpProfMapDescription match the intended QoS policy, and check tMplsLspExpProfileTable/tMplsLspExpProfileEntry for the tMplsLspExpProfileBits assigned to each profile. Monitoring tMplsLspExpProfMapLastChanged or tMplsLspExpProfileLastChanged lets an operator detect unexpected QoS policy changes without polling every mapping entry. An EXP profile mapping that doesn't match its documented tMplsLspExpProfMapDescription would signal drift between intended and actual MPLS QoS treatment.

What Can Be Monitored

  • MPLS EXP-to-QoS profile mappings
  • EXP profile bit definitions
  • QoS mapping/profile row status
  • last configuration change timestamps for QoS profiles

FAQ

How would TIMETRA-SAS-QOS-MIB help verify QoS on an Alcatel-Lucent/Nokia 7x50 SAS switch?
It exposes the MPLS EXP-bit profile mapping table (tMplsLspExpProfMapTable) and EXP profile definitions (tMplsLspExpProfileTable) used to classify and schedule traffic at the network access edge. An operator can poll these tables to confirm the EXP-to-QoS mapping matches the intended provisioning, since a misconfigured mapping would give traffic the wrong forwarding treatment.

Does TIMETRA-SAS-QOS-MIB report hardware faults like temperature or power?
No — its monitoring value is around configuration/software state: verifying QoS profile mappings and row status and tracking last-configuration-change timestamps, not physical sensor data; hardware health is covered by other MIBs in the TIMETRA family.
