Category: VLAN and Bridging, Vendor: H3C/HH3C

Description: Manages protocol-based VLAN assignment on H3C/3Com switches, allowing automatic VLAN classification of traffic based on L3 protocol type.

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-PROTOCOL-VLAN-MIB?

A3COM-HUAWEI-PROTOCOL-VLAN-MIB manages protocol-based VLAN assignment on H3C/3Com switches, a Layer-2 feature that classifies untagged incoming frames into a VLAN based on their Layer-3 protocol type (such as IPv4, IPv6, or IPX) rather than port or 802.1Q tag alone. It is expected to expose per-port protocol-to-VLAN mapping configuration and the set of protocol templates recognized by the switch. As a Layer-2 configuration MIB it primarily supports monitoring of the switch's traffic-classification software state, confirming which protocol types are mapped to which VLAN on a given port, rather than physical hardware health. Dependency: it builds on the standard 802.1Q bridge VLAN model, adding H3C-specific protocol-based classification not present in the base bridge MIB. Deployment is on H3C/3Com access-layer switches in mixed-protocol environments needing automatic VLAN segregation without relying on explicit tagging. Engineers can download the A3COM-HUAWEI-PROTOCOL-VLAN-MIB file directly to load it into their MIB browser.

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

  • H3C/3Com LAN switches

Monitoring Examples

No specific object or table names were provided in the sampled source for this module, so a concrete OID-level example is not given here to avoid inventing identifiers. In practice an admin would poll the per-port protocol-VLAN mapping table to confirm, for instance, that legacy IPX traffic on a port is correctly isolated into its designated VLAN, and traffic appearing in the wrong VLAN would indicate a protocol-template misconfiguration on that port.

What Can Be Monitored

  • per-port protocol-to-VLAN mapping
  • configured protocol templates
