Description: MIB for configuring and monitoring ESCON fiber channel interface ports and performance counters on Smartoptics SiteLight optical transport modules

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 SL-ESCON-MIB?

SL-ESCON-MIB is a vendor MIB from Smartoptics for ESCON (Enterprise Systems Connection) fiber-channel interface ports carried over its SiteLight optical transport platform, a legacy IBM mainframe channel protocol still tunneled over optical transport in some enterprise environments. It exposes port configuration and login state alongside a rich set of performance-monitoring (PM) counters collected over defined measurement intervals. Its monitoring value is heavily performance/fault oriented: esconPortConfigLoginState shows whether the ESCON link has successfully logged in, esconPortCurrentRxSigLosses and esconPortCurrentRxSyncLosses flag signal or synchronization loss events, and esconPortCurrentRxLinkFailures directly counts link failures, while esconPortCurrentRxOctets/RxPkts provide throughput baselines — together revealing a degrading or flapping ESCON connection. The MIB is part of the SiteLight family and shares its transport-layer conventions with related MIBs like SL-VCG-MIB. It is deployed where ESCON channel extension is still required, such as legacy mainframe-to-storage links carried over modern optical transport equipment, and administrators can download the SL-ESCON-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SL-ESCON-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

  • Smartoptics SiteLight optical transport platform (ESCON interface module)

Monitoring Examples

An administrator would check esconPortConfigLoginState to confirm an ESCON port has completed protocol login, and poll esconPortCurrentTable/esconPortCurrentEntry indexed by esconPortCurrentIndex for esconPortCurrentRxSigLosses and esconPortCurrentRxSyncLosses to detect intermittent optical signal problems. A rising esconPortCurrentRxLinkFailures counter combined with esconPortConfigValidIntervals (the number of complete PM intervals available) would indicate a chronically unstable channel needing physical-layer investigation, and esconPortResetPmCounters can be invoked to clear counters after a fix is applied.

What Can Be Monitored

  • ESCON login state
  • received octets/packets
  • signal loss events
  • synchronization loss events
  • link failure count
  • PM interval validity

How to Use in IPNetwork Monitor

Example using esconPortCurrentRxOctets OID:

Select a Smartoptics SiteLight optical transport platform, ESCON interface module (link login/signal-loss statistics) 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 esconPortCurrentRxOctets into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of octets of data received during the current interval. 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 Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
