Description: Provides management of Fibre Channel Fabric Configuration Server functionality, including topology discovery across Fabrics.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring T11-FC-FABRIC-CONFIG-SERVER-MIB with a free 30-day trial of IPNetwork Monitor.

What Is T11-FC-FABRIC-CONFIG-SERVER-MIB?

T11-FC-FABRIC-CONFIG-SERVER-MIB is a vendor-neutral T11/FC-GS-5 standards MIB for managing the Fibre Channel Fabric Configuration Server (FCS) function on a Fibre Channel switch, which discovers and reports the topology and configuration of interconnected switches, hubs, and bridges (Interconnect Elements) making up an FC SAN fabric. It exposes objects to trigger a fabric discovery scan over a specified range, track discovery status/completion time, and retrieve the resulting inventory of discovered Interconnect Elements. In terms of monitoring, its principal value is topology and software-process status: discovery status and completion-time objects reveal whether a fabric discovery job is running, completed, or failed/timed out, functioning as a job-status indicator, while the resulting Interconnect Element table provides an up-to-date inventory of switches/devices in the fabric that can be checked against an expected baseline to detect an unexpected topology change. This MIB is defined by the T11 FC-GS-5 standard and is meant to be used alongside other Fibre Channel MIBs (e.g., FC-MGMT, FC zoning MIBs) for a complete SAN management picture, rather than in isolation. Typical deployment context is an enterprise or data-center Fibre Channel SAN switch used to interconnect storage arrays and servers, where fabric-wide topology visibility supports SAN troubleshooting and change detection. Engineers implementing or auditing this functionality typically reference the T11-FC-FABRIC-CONFIG-SERVER-MIB RFC/standard documentation for the authoritative specification.

IPNetwork Monitor allows you to monitor SNMP objects defined in T11-FC-FABRIC-CONFIG-SERVER-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

  • vendor-neutral, T11 FC-GS-5 standards-based MIB, not tied to a specific manufacturer
  • Fibre Channel SAN switches

Monitoring Examples

An administrator would set parameters in t11FcsFabricDiscoveryTable/t11FcsFabricDiscoveryEntry (t11FcsFabricDiscoveryRangeLow/RangeHigh and t11FcsFabricDiscoveryTimeOut) and trigger t11FcsFabricDiscoveryStart to kick off a fabric scan, then poll t11FcsDiscoveryStateTable/t11FcsDiscoveryStateEntry via t11FcsFabricIndex to check t11FcsDiscoveryStatus and t11FcsDiscoveryCompleteTime for job completion. Once complete, t11FcsIeTable would be walked to enumerate the discovered switches/hubs/bridges in the fabric, and a comparison against a prior discovery would reveal if an Interconnect Element unexpectedly disappeared, indicating a switch failure or a fabric partition. A discovery that times out or reports a failed status directly indicates a fabric-wide connectivity or configuration problem rather than a single-device fault.

What Can Be Monitored

  • fabric discovery status
  • fabric discovery completion time
  • discovered Interconnect Element inventory
  • discovery range/timeout configuration
  • per-fabric discovery state

How to Use in IPNetwork Monitor

Example using t11FcsInGetReqs OID:

Select a device implementing T11-FC-FABRIC-CONFIG-SERVER-MIB 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 t11FcsInGetReqs 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 number of Get Requests received by the Fabric Configuration Server on this Fabric. 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 Counter32-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.
