Description: Provides management objects for monitoring Fibre Channel fabric element statistics and port performance on Cisco MDS SAN switches.

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 CISCO-FC-FE-MIB?

CISCO-FC-FE-MIB is a Cisco Fibre Channel fabric element management MIB for MDS SAN switches, extending the standard IF-MIB and the FIBRE-CHANNEL-FE-MIB with Cisco-specific fabric port objects. It exposes configuration data (admin mode, admin speed, trunk mode, port channel membership) and operational status data (operational mode, operational status cause, beacon mode) for Fibre Channel ports including N_port, NL_port, E_port, and B_port types. It is explicitly useful for monitoring hardware/link status of SAN fabric ports: fcIfOperMode and fcIfOperStatusCause/fcIfOperStatusCauseDescr reveal why a port is up, down, or in a particular operating mode, which is critical for diagnosing SAN connectivity issues. It has a notable dependency on both the standard IF-MIB (as a Cisco extension) and the FIBRE-CHANNEL-FE-MIB standard, whose relevant groups it incorporates. It is deployed on Cisco MDS 9000 series SAN switches interconnecting storage arrays and hosts. Network engineers evaluating or troubleshooting this functionality can download the CISCO-FC-FE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-FC-FE-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

  • Cisco MDS Fibre Channel SAN switches

Monitoring Examples

An engineer would poll fcIfTable/fcIfEntry to check fcIfOperStatusCause and fcIfOperStatusCauseDescr on a port reporting down, and compare fcIfAdminMode/fcIfAdminSpeed against fcIfOperMode to detect a speed or mode mismatch. Repeated changes in fcIfOperStatusCause on an Nx_port would point to a flapping host or storage connection, while fcIfPortChannelIfIndex helps identify whether the affected port is part of a port-channel bundle.

What Can Be Monitored

  • FC port admin/operational mode
  • port operational status cause
  • port speed configuration
  • trunk mode and port-channel membership
  • beacon mode status

How to Use in IPNetwork Monitor

Example using fcIfLinkFailures OID:

Select a Cisco MDS Fibre Channel SAN switch 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 fcIfLinkFailures 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 link failures detected by the FC-Port. 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 between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
