Description: Manages Data Center Bridging (DCB) configuration and priority flow control for DF10 equipment.

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 DF10-DCB-MIB?

DF10-DCB-MIB is Dell's proprietary extension MIB for Dell Networking OS (Force10-derived) switches, managing Data Center Bridging (DCB) and DCBX (DCB Exchange) features such as Priority-based Flow Control (PFC) and Enhanced Transmission Selection (ETS) used in converged/lossless Ethernet fabrics (e.g., for FCoE or iSCSI traffic). It exposes configuration objects for DCB applications, DCBX negotiation, and ETS bandwidth/priority group settings, along with notification objects for DCB-related events. Its role in monitoring is chiefly software/protocol status: DCBX negotiation state and application priority mappings must be correctly matched between switch and end-host/adapter to avoid lossless-traffic disruptions, and notifications flag misconfigurations or negotiation failures. It's explicitly an extension to the standard Dell Networking OS management framework, complementing IEEE DCB standards (802.1Qbb PFC, 802.1Qaz ETS/DCBX). It's typically deployed on Dell/Force10 data center switches supporting converged Ethernet fabrics carrying storage and LAN traffic together, and administrators can download the DF10-DCB-MIB file to load it directly into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in DF10-DCB-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

  • Dell Networking (Force10) data center switch

Monitoring Examples

An admin would poll dF10DcbApplicationObjects to confirm the priority-to-application (e.g., FCoE, iSCSI) mapping matches expectations on a given switch port, and check dF10DCBXObjects to verify DCBX negotiation with an attached converged network adapter completed successfully rather than falling back to defaults. Monitoring dF10ETSObjects reveals whether bandwidth allocation across traffic classes (ETS priority groups) matches the configured policy, and a mismatch here could starve storage traffic of guaranteed bandwidth. dF10DcbNotificationObjects would be watched for DCBX peer change or configuration-mismatch traps indicating a cabling or adapter configuration issue.

What Can Be Monitored

  • DCBX negotiation state
  • priority flow control (PFC) configuration
  • ETS bandwidth/priority group allocation
  • application-to-priority mapping
  • DCB configuration change notifications

How to Use in IPNetwork Monitor

Example using dF10DCBXPortMultiplePeerCount OID:

Select a Dell Networking (Force10) data center switch (DCB/DCBX) 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 dF10DCBXPortMultiplePeerCount 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. Indicates number of times multiple peers were detected. 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.
