Description: Manages VLAN creation, port membership, and trunk configuration on H3C Layer 2 switch platforms.

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 HH3C-LswVLAN-MIB?

HH3C-LswVLAN-MIB is an H3C vendor MIB for managing VLAN configuration on H3C Layer 2 switch platforms. It exposes VLAN creation/deletion status, per-port VLAN membership (access/trunk), and trunk allowed-VLAN lists, giving a configuration-oriented view of Layer 2 segmentation. Its monitoring role is mainly around configuration and software state consistency: verifying that a port's actual VLAN membership matches intended design, and detecting orphaned or misconfigured VLANs that could cause traffic isolation failures. It supplements the IETF Q-BRIDGE-MIB, which defines the standard VLAN object model that H3C's implementation extends with vendor-specific controls. It is used on H3C access, distribution, and core switches in enterprise LAN environments that rely on VLAN segmentation for traffic isolation. Engineers can download the HH3C-LswVLAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-LswVLAN-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

  • H3C Layer 2 switch

Monitoring Examples

No sample object names were provided in the source for this module, so specific OIDs cannot be cited, but typical monitoring involves polling per-port VLAN membership and trunk allowed-VLAN lists to confirm a port is carrying only the VLANs intended for it. A port unexpectedly missing from a VLAN's member list, or a trunk's allowed-VLAN range drifting from the documented design, would indicate a configuration error or unauthorized change.

What Can Be Monitored

  • VLAN existence/status
  • per-port VLAN membership
  • trunk allowed-VLAN list
  • access vs trunk port mode

How to Use in IPNetwork Monitor

Example using hh3cVLANMibSwitchGMRPRXPkt OID:

Select an H3C Layer 2 switch (VLAN configuration) 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 hh3cVLANMibSwitchGMRPRXPkt 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. It reports the number of GMRP frames received. 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.
