Description: Manages VLAN creation, membership, and port assignment on Dell Layer 2/3 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-vlan-MIB?

Dell-vlan-MIB is a Dell-private MIB for managing VLAN configuration on Dell Layer 2/3 network switches, covering VLAN creation, naming, tagging, port membership modes, and related switch behavior. It exposes configuration objects such as VLAN name/tag/ifIndex mappings, per-port VLAN mode state, default VLAN handling, voice VLAN support, and flooding behavior for unknown unicast traffic. This is primarily a configuration-status MIB used to confirm the software-level VLAN setup on a switch is correct rather than hardware health, though verifying VLAN state is essential to confirming a switch's forwarding behavior is functioning as intended. It has no explicit dependency noted beyond standard Dell switch management conventions, and it commonly complements the standard Q-BRIDGE-MIB used for 802.1Q VLAN management. It is typically deployed on Dell PowerConnect/Networking series switches in enterprise LAN environments where VLAN segmentation and voice VLAN features are configured via SNMP, typically after a Dell-vlan-MIB download to load the module into a MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Dell-vlan-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 / Networking switch

Monitoring Examples

An administrator can walk vlanNameTable/vlanNameEntry to confirm VLAN names, tags (vlanNameTag), and associated interfaces (vlanNameIfIndex) match the intended design. Checking vlanPortModeTable/vlanPortModeEntry and vlanPortModeState reveals whether a port is in access, trunk, or general mode, which would explain unexpected tagging behavior. The vlanVoice and vlanDefault objects let an operator confirm voice VLAN and default VLAN assignments are correctly applied to avoid VoIP phones landing on the wrong VLAN.

What Can Be Monitored

  • VLAN name-to-tag-to-interface mapping
  • per-port VLAN mode (access/trunk)
  • voice VLAN configuration
  • default VLAN assignment
  • unknown-unicast flooding behavior
