Description: EdgeLink MIB for managing edge network link aggregation and failover providing link state and traffic statistics.

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 EDGELINK-MIB?

EDGELINK-MIB is a vendor MIB for "EdgeLink" edge-network equipment; despite its general short description referencing link aggregation and failover, the actual objects captured for this module (elDS1CMTable and related elDS1CM* objects) show it is really focused on DS1 (T1) Channelized Module management — configuring and monitoring individual DS1 channels on an edge access device. It exposes a DS1 channel-module table covering per-channel line coding, line build-out, loopback mode, service mode, and interface equipping status. Its monitoring value is hardware/interface status oriented: whether a DS1 channel is equipped and in service (elDS1CMInterfaceEquipped, elDS1CMServiceMode), its current input signal status (elDS1CMInputStatus), whether it is in a test loopback (elDS1CMLoopbackMode), and mask/alarm state (elDS1CMMaskState) — all classic T1 line-card health indicators. It builds on the standard DS1/E1 line concepts found in the IETF DS1-MIB (RFC 3895) though implemented as a vendor-specific channelized-module table. It is deployed on edge access/multiplexer equipment terminating T1 lines, where technicians monitor individual DS1 channels for signal loss, misconfiguration, or active test loopbacks. Network engineers evaluating or troubleshooting this functionality can download the EDGELINK-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EDGELINK-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

Edge access multiplexer/DS1 channelized module device

Monitoring Examples

An admin can poll elDS1CMTable/elDS1CMEntry indexed by elDS1CMChannelNumber to read elDS1CMInputStatus and elDS1CMMaskState, detecting a T1 channel that has lost signal or is in an alarm condition. Checking elDS1CMLoopbackMode across channels would reveal a channel left in test loopback that should have been returned to normal service, and elDS1CMLineCode/elDS1CMLineBuildout confirm the channel's line configuration matches the connected carrier circuit.

What Can Be Monitored

per-channel input signal status
channel equipped/in-service state
loopback mode
line code/line build-out configuration
channel alarm/mask state
