Category: SNA and Legacy Protocols, Vendor: 3Com

Description: Manages Synchronous Data Link Control (SDLC) interfaces and SNA sessions on 3Com routers, covering SDLC link stations and frame 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 A3COM-SDLC-R1-MIB?

A3COM-SDLC-R1-MIB is a legacy 3Com (enterprise OID 43) proprietary MIB configuring SDLC (Synchronous Data Link Control) ports. Its admin table, keyed by port, records name, role, type, topology, activation timeout, pause, and slow-poll timer, mirrored by an operational table showing current values (which may lag configured values until the interface restarts) plus last-failure time/cause, and a stats table records physical failures and invalid addresses. As a configuration/status MIB it lets an administrator confirm SDLC port configuration and diagnose port failures on legacy 3Com SNA gateway equipment. It is deployed on legacy 3Com SDLC/SNA gateway equipment. Engineers can download the A3COM-SDLC-R1-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-SDLC-R1-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

  • Legacy 3Com SDLC/SNA gateway equipment

Monitoring Examples

An administrator checks sdlcPortOperLastFailCause and sdlcPortStatsPhysicalFailures to diagnose a failing SDLC port on legacy 3Com SNA gateway equipment.
