Description: Provides bridge MIB extension objects for the Dell VRTX integrated chassis switch.

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-VRTX-BRIDGEMIBOBJECTS-MIB?

Dell-VRTX-BRIDGEMIBOBJECTS-MIB is a Dell proprietary MIB (built on Dell-VRTX-MIB) extending bridge/spanning-tree management for the Dell VRTX platform with per-VLAN bitmap encoding (each bit representing one of VLANs 1-4094, split across VlanList1-4). Its objects cover priority-port-group version/table (number), STP MIB version/type/enable, port-must-belong-to-VLAN flag, extended-port-number-format flag, and a per-VLAN STP table (enable, time since topology change, topology-change count, designated root, root cost/port, max age, hello time, hold time, forward delay), plus a per-VLAN-per-port STP table. As a configuration/status MIB it lets an administrator confirm per-VLAN spanning-tree topology and root-bridge state on a Dell VRTX switch. It is deployed on Dell VRTX platform switching equipment. Engineers can download the Dell-VRTX-BRIDGEMIBOBJECTS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-VRTX-BRIDGEMIBOBJECTS-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 VRTX platform switching equipment

Monitoring Examples

An administrator checks rldot1dStpVlanTable and rldot1dStpDesignatedRoot to confirm per-VLAN spanning-tree topology on a Dell VRTX switch.

What Can Be Monitored

How to Use in IPNetwork Monitor

Example using rldot1dStpTopChanges OID:

Select a Dell PowerEdge VRTX chassis switch module (per-VLAN spanning tree) 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 rldot1dStpTopChanges 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 topology changes detected by this bridge since the management entity was last reset or initialized. 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.
