Description: Extreme Networks MIB for Packet over SONET/SDH (POS) interface management on Extreme Networks routing platforms.

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 EXTREME-POS-MIB?

EXTREME-POS-MIB is an Extreme Networks vendor MIB providing objects common to Packet over SONET/SDH (POS) interfaces on Extreme's routing platforms, layering vendor-specific POS attributes on top of standard SONET/interface MIBs. It exposes POS interface configuration and status objects shared across different POS-capable line cards and platforms. As a hardware/interface status MIB it's used to monitor the operational and physical-layer health of SONET/SDH links — such as line/section alarm status, framing mode, and interface operational state — which reveal a degraded or failed optical transport link. It's explicitly described as objects "common to POS MIBs," implying it is shared across other Extreme POS-related modules and likely aligns with standard SONET-MIB (RFC 3592) concepts. It's typically deployed on Extreme Networks routing platforms carrying SONET/SDH-based WAN circuits, such as service-provider or enterprise WAN edge routers. Network engineers evaluating or troubleshooting this functionality can download the EXTREME-POS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-POS-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

Extreme Networks routing platform with POS/SONET interfaces

Monitoring Examples

No sample objects were provided for this module, so specific object names can't be confirmed; based on its description, an admin would typically poll POS interface status and alarm objects to check for framing errors or loss-of-signal conditions, which would indicate a failing optical transceiver or a SONET/SDH transport problem.

What Can Be Monitored

POS interface operational status
SONET/SDH alarm status
framing mode
interface configuration
