Description: Manages STS-1 synchronous transport signal configuration and performance monitoring in ERI DNX SONET interfaces.

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 ERI-DNX-STS1-MIB?

ERI-DNX-STS1-MIB is a vendor-specific MIB from ERI (Enterprise MIB) managing STS-1 Synchronous Transport Signal mapping and configuration on DNX SONET transport devices. It exposes objects describing STS-1 mapper resources, their addressing, and the associated VT (Virtual Tributary) group mappings used to carry lower-rate signals inside a SONET STS-1 frame. This MIB is used to monitor the hardware configuration and diagnostic status of SONET transport cards, covering mapper resource assignment, VT group-to-tributary mapping, and diagnostic/alarm state that reveal misconfigured or failing SONET interfaces. As a SONET transport MIB it is typically deployed alongside related transmission MIBs (e.g., SONET-MIB) rather than as a standalone standard. It is used by telecom and enterprise network operators running DNX SONET multiplexing equipment, who rely on the ERI-DNX-STS1-MIB MIB Browser view to keep STS-1 tributary mappings and interface health under observation.

IPNetwork Monitor allows you to monitor SNMP objects defined in ERI-DNX-STS1-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

ERI DNX SONET STS-1 multiplexer/transport device

Monitoring Examples

An engineer would poll sts1MapperConfigTable/sts1MapperConfigEntry using sts1MapperAddr and sts1MapperResource to confirm a given STS-1 mapper card is correctly provisioned, then check sts1VtGroup1 through sts1VtGroup7 and sts1VtMapping to verify each virtual tributary group is mapped to the expected downstream circuit. The sts1Diag branch is checked when a circuit reports errors, to isolate whether the fault is in the mapper hardware or the tributary mapping itself. Under dnxSTS1/sts1Config, changes to mapping assignments are audited to catch accidental tributary reassignment that would silently reroute traffic.

What Can Be Monitored

STS-1 mapper resource assignment
VT group-to-tributary mapping
mapper diagnostic/alarm state
SONET interface configuration

How to Use in IPNetwork Monitor

Example using sts1LIUBertErrSecs OID:

Select an ERI DNX SONET multiplexer as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type sts1LIUBertErrSecs into the Find box to locate it in the OID tree, then select it and click OK. This is the number of LIU Bert Errored seconds. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
