Description: Manages switch VLAN configuration, port membership, and per-VLAN operational state.

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 SWITCH-VLAN-MIB?

SWITCH-VLAN-MIB is a Hitachi Computer Products module, from their Network System Group "SWITCH" product line, providing VLAN configuration objects modeled on IEEE 802.1Q VLAN concepts. Based on its stated purpose, it exposes VLAN definitions, per-port VLAN membership, and per-VLAN operational state. Its monitoring emphasis is software/configuration status of VLAN assignment - confirming ports are members of the correct VLANs and that each VLAN is operationally active, which helps detect misconfigured VLAN membership causing unintended connectivity or segmentation issues. It parallels the semantics of the standard IEEE 802.1Q Bridge MIB (Q-BRIDGE-MIB) though implemented as a Hitachi-proprietary module. It is deployed on Hitachi enterprise/data-center switches requiring VLAN-based traffic segmentation. Network engineers evaluating or troubleshooting this functionality can download the SWITCH-VLAN-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

No concrete object or table names were provided for this module in the source excerpt, so specific identifiers can't be cited. Based on its stated purpose, an operator would poll VLAN membership and per-VLAN operational-state objects to confirm a given port is assigned to the correct VLAN after a configuration change. A port unexpectedly reporting membership in the wrong VLAN, or a VLAN showing as operationally inactive, would explain unexpected connectivity loss or improper traffic segmentation.
