Description: Manages Nokia carrier Ethernet service access point configuration and binding.

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 TN-SAP-MIB?

TN-SAP-MIB is a Nokia (Alcatel-Lucent SR OS lineage) carrier Ethernet MIB module that manages Service Access Points (SAPs) -- the logical service-edge bindings between a physical port/encapsulation and a customer service instance. It exposes configuration data such as port and encapsulation identifiers, administrative/operational status, and ingress QoS and filter policy assignments for each SAP. It is directly useful for monitoring software/service status on the router: the admin-versus-operational status fields reveal whether a configured service access point is actually passing traffic, which is critical for detecting misconfigured encapsulation or filter bindings. It builds on top of underlying interface/port MIBs (such as IF-MIB) for the physical layer and is one module within Nokia's larger SR OS service-management MIB suite covering SDPs, QoS, and filters. It is typically deployed on carrier Ethernet edge and metro aggregation routers delivering business or residential Ethernet services, and operators typically download TN-SAP-MIB directly from Nokia's SR OS MIB reference package before loading it into their NMS.

IPNetwork Monitor allows you to monitor SNMP objects defined in TN-SAP-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 7x50 Service Router family, entire product line (Service Access Point admin/oper status)

Monitoring Examples

tnSapBaseInfoTable/tnSapBaseInfoEntry rows keyed by tnSapPortId and tnSapEncapValue identify each SAP; comparing tnSapAdminStatus against tnSapOperStatus reveals a SAP that is administratively enabled but operationally down, often due to an encapsulation mismatch, while tnSapIngressQosPolicyId and tnSapIngressMacFilterId/tnSapIngressIpFilterId show which QoS and filter policies are bound to ingress traffic on that access point.

What Can Be Monitored

  • SAP admin/operational status
  • SAP port and encapsulation binding
  • ingress QoS policy assignment
  • ingress MAC/IP filter assignment
  • SAP row status/provisioning state
