Description: Manages sFlow packet sampling configuration and statistics export on Dell network 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 Dell-SFLOW-MIB?

Dell-SFLOW-MIB is a Dell private MIB for configuring sFlow packet sampling and statistics export on Dell network switches. It exposes configuration objects controlling sFlow sampling rates, polling intervals, and collector (receiver) destinations, used to export traffic flow statistics for network traffic analysis. Its monitoring value is primarily around confirming the sFlow feature itself is correctly configured and actively exporting data (a software/telemetry-pipeline health concern) rather than hardware faults directly, though it indirectly supports broader traffic/performance monitoring once flows reach an sFlow collector. No specific sample object names were available in the source, so exact object identifiers cannot be confirmed. It is deployed on Dell switches in networks where centralized traffic visibility and analysis via an sFlow collector (e.g., for capacity planning or anomaly detection) is required. Engineers can download the Dell-SFLOW-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-SFLOW-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.

Monitoring Examples

No sample object names were provided in the source, so specific OIDs cannot be cited; based on the module's stated purpose an admin would typically confirm the configured sFlow sampling rate, polling interval, and collector IP/port are correctly set on each monitored interface. A collector that stops receiving sFlow datagrams despite correct configuration would point to an export path or agent-side sFlow process problem this MIB's status objects are meant to surface.

What Can Be Monitored

sFlow sampling rate configuration
sFlow polling interval

How to Use in IPNetwork Monitor

Example using rlsFlowStatisticsSampledPackets OID:

Select a Dell PowerConnect/Networking managed switch (sFlow sampling/export) 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 rlsFlowStatisticsSampledPackets 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. Counts the number of packets sampled by sFlow per interface. 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.
