Description: Manages subnet-based VLAN assignment on H3C/3Com switches, enabling automatic VLAN classification of traffic based on source IP subnet.

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 A3COM-HUAWEI-SUBNET-VLAN-MIB?

A3COM-HUAWEI-SUBNET-VLAN-MIB is an H3C/3Com private MIB for configuring subnet-based VLAN assignment, a feature that classifies untagged traffic into a VLAN based on the source IP subnet rather than port or MAC address. It exposes global counts of configured subnet-VLANs and subnet-VLAN ports, plus a table mapping VLAN ID, subnet index, IP address/mask, and address type per subnet-VLAN entry with row-status control for adding or removing entries. Its monitoring role is primarily configuration-status: an operator verifies that subnet-to-VLAN mappings are correctly provisioned and active, and checks aggregate counts against expected totals to catch missing or duplicate entries. It relies on the device's underlying VLAN and IP addressing infrastructure and is typically used alongside standard Q-BRIDGE-MIB VLAN objects for full context. It is deployed on H3C/3Com Layer 2/Layer 3 switches where traffic must be segmented into VLANs based on IP subnet rather than static port assignment. Engineers can download the A3COM-HUAWEI-SUBNET-VLAN-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-SUBNET-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

An operator walks h3cSubnetVlanTable/h3cSubnetVlanEntry to verify h3cSubnetVlanVlanId, h3cSubnetVlanIpAddressValue, and h3cSubnetVlanNetMaskValue match the intended subnet-to-VLAN design, checking h3cSubnetVlanRowStatus to confirm each entry is active rather than left in a notReady state. Comparing h3cSubnetNumAllVlan/h3cSubnetNumPerVlan and h3cSubnetNumAllPort/h3cSubnetNumPerPort against expected provisioning totals would reveal a subnet-VLAN binding that failed to apply on a given port.

What Can Be Monitored

subnet-to-VLAN mappings
subnet-VLAN entry row status
configured VLAN/port counts
IP subnet and mask per VLAN entry
