Description: Monitors per-VLAN traffic counters including ingress, egress, and dropped frames on D-Link 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 VLAN-COUNTER-MIB?
VLAN-COUNTER-MIB is a vendor-specific (D-Link) enterprise MIB that structures per-VLAN traffic counters on managed switches. It exposes performance/traffic-counter data — ingress, egress, and dropped frame counts scoped to individual VLANs rather than physical ports. While primarily a traffic-statistics MIB rather than a hardware-health MIB, its counters are useful for spotting a misbehaving VLAN, such as one dropping an abnormal share of frames, which can be an early indicator of a congested or faulty switch. It is a proprietary D-Link module that likely depends conceptually on standard bridge/VLAN MIBs (Q-BRIDGE-MIB) for VLAN identification even though it defines its own counter tables. It is typically deployed on D-Link managed switches in enterprise or campus networks where administrators need per-VLAN traffic visibility beyond standard interface counters, which is exactly what the VLAN-COUNTER-MIB MIB is designed to provide.
IPNetwork Monitor allows you to monitor SNMP objects defined in VLAN-COUNTER-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
- D-Link managed switch
Monitoring Examples
An administrator would poll a per-VLAN counter table (indexed by VLAN ID) for ingress and egress octet/frame counts to baseline normal traffic on a given VLAN, then watch the dropped-frame counter to detect congestion or a misconfigured trunk. A sudden spike in dropped frames on one VLAN while others remain normal would point to a specific broadcast storm or oversubscribed uplink tied to that VLAN. Because no explicit sample objects were provided for this module, exact table/column names are inferred from the short description's mention of ingress, egress, and dropped counters.
What Can Be Monitored
- per-VLAN ingress frame/octet count
- per-VLAN egress frame/octet count
- per-VLAN dropped frame count
