Description: Defines managed objects for managing the Fibre Channel Name Server function, including registered port names and node names.

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

What Is T11-FC-NAME-SERVER-MIB?

T11-FC-NAME-SERVER-MIB is a T11 (INCITS technical committee for Fibre Channel) standard MIB (RFC 4438) managing the FC-GS-4 Name Server (NS) functionality in a Fibre Channel fabric. Its info-subset table, keyed by index, records switch index, last-change time, row count, total-rejects count, and a reject-notification-enable flag, while a registration table records fabric index, port identifier/name, node name, class of service, node IP address, process associator, FC-4 type, port type/IP address, fabric port name, hard address, and symbolic port/node names/features. As a status MIB it lets an administrator query registered Fibre Channel node/port identities and their capabilities via the fabric Name Server. It is deployed on Fibre Channel fabric switching equipment (Name Server, FC-GS-4). Engineers can download the T11-FC-NAME-SERVER-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in T11-FC-NAME-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

  • Fibre Channel fabric switching equipment (Name Server, FC-GS-4)

Monitoring Examples

An administrator checks t11NsRegNodeName and t11NsRegFc4Type to identify a registered Fibre Channel node's identity and supported upper-layer protocol via the fabric Name Server.

What Can Be Monitored

  • Fibre Channel Name Server node/port registration

How to Use in IPNetwork Monitor

Example using t11NsInfoSubsetTotalRejects OID:

Select a Fibre Channel fabric switching equipment, Name Server FC-GS-4 (registered node/port identity status) 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 t11NsInfoSubsetTotalRejects 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 (CT_IU) Requests for Name Server functions that were rejected for inclusion in this Name Server Information Subset, across all Fabrics for which it contains information. 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.
