Description: Eicon Technology SDLC MIB for managing Synchronous Data Link Control protocol connections on Eicon communications adapters.

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 EICON-SDLC-MIB?

EICON-SDLC-MIB is Eicon Technology's vendor MIB for managing Synchronous Data Link Control (SDLC) protocol connections on Eicon communications adapters, used to bridge legacy IBM SNA/SDLC traffic over modern networks. It exposes per-port SDLC link configuration such as timers, retry counts, and window/frame sizes via sdlcCfgTable, along with a companion sdlcInfoTable that carries runtime link status/statistics. This supports monitoring the software/protocol-layer status of legacy SDLC links: configuration parameters like sdlcCfgMaxRetryCount and the timer values (sdlcCfgT1 through sdlcCfgT4) directly affect link reliability, and the info table reports live link state, useful for diagnosing SDLC session instability or excessive retransmissions on the adapter. It sits within Eicon's own enterprise MIB tree (eicon/management/mibv2) and depends on the underlying SDLC protocol conventions rather than any IETF standard MIB. It is typically deployed on Eicon communications adapters/gateways bridging legacy IBM mainframe SNA/SDLC connections into modern IP networks. Engineers can download the EICON-SDLC-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in EICON-SDLC-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.

Monitoring Examples

sdlcCfgTable/sdlcCfgEntry expose per-port settings like sdlcCfgPortRef, sdlcCfgMaxLinkStation, sdlcCfgT1 through sdlcCfgT4 (link timers), sdlcCfgMaxFrameSz, and sdlcCfgMaxRetryCount, letting an admin verify SDLC link parameters match the remote SNA endpoint's requirements. An admin troubleshooting frequent SDLC link drops would check sdlcCfgMaxRetryCount and the timer values for misconfiguration, then consult sdlcInfoTable for live link status/statistics. This MIB is central to keeping legacy mainframe connectivity through Eicon adapters healthy in mixed SNA/IP environments.

What Can Be Monitored

SDLC link configuration (timers, retry count, window/frame size)
max link stations per port
