Description: Manages the Dell PowerConnect 3248 Layer 2 switch, providing port, VLAN, spanning-tree, and SNMP configuration objects.

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 PowerConnect3248-MIB?

PowerConnect3248-MIB is Dell's proprietary MIB for the PowerConnect 3248 Layer 2 Ethernet switch, exposing switch-wide identification and configuration alongside per-unit hardware/firmware version and port information. It covers VLAN management (switchManagementVlan), spanning-tree and port configuration, and a per-unit switchInfoTable reporting hardware, microcode, loader, and boot ROM firmware versions. It is heavily oriented toward hardware and software status monitoring — swHardwareVer, swMicrocodeVer, swLoaderVer, and swBootRomVer let an admin confirm exactly which firmware/hardware revisions are running on each stack unit, while swPowerStatus reports power supply health and swPortNumber tracks port inventory. As a Dell private enterprise MIB it relies on standard SNMP framework conventions and likely complements standard BRIDGE-MIB/IF-MIB objects for VLAN and interface data rather than replacing them. It is deployed on Dell PowerConnect 3248 stackable Layer 2 switches in enterprise wiring-closet and small-to-midsize network deployments. Engineers can download the PowerConnect3248-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in PowerConnect3248-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 PowerConnect 3248 stackable Layer 2 Ethernet switch

Monitoring Examples

An administrator can poll switchInfoTable via swUnitIndex to check swHardwareVer, swMicrocodeVer, swLoaderVer, and swBootRomVer, confirming firmware consistency across a stack of PowerConnect 3248 units before or after an upgrade. Checking swPowerStatus for a given unit reveals whether its power supply is healthy, and switchManagementVlan combined with switchNumber lets an operator confirm which VLAN is designated for management access to the stack.

What Can Be Monitored

  • hardware/microcode/loader/boot ROM firmware versions
  • power supply status
  • management VLAN configuration
  • port count/inventory
  • per-unit stack index

How to Use in IPNetwork Monitor

Example using xstInstancePortForwardTransitions OID:

Select a Dell PowerConnect 3248 stackable Layer 2 Ethernet 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 xstInstancePortForwardTransitions 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 times this port has transitioned from the Learning state to the Forwarding state. 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.
