What Is A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB?
This MIB manages IEEE 802.1D bridging functions on 3Com SuperStack switching systems, covering spanning tree, MAC forwarding database, and per-bridge/per-port settings across a switch's bridge instances. It exposes data such as the number of bridges and ports present, forwarding-address-table size/usage/peak-usage counts, and bridge operating mode, alongside standard spanning-tree parameters. From a status-monitoring standpoint, the address-table usage counters are especially useful for detecting when a switch's MAC table is approaching capacity, a common cause of flooding and performance degradation. It extends and works alongside the standard IETF BRIDGE-MIB (RFC 4188/1493) for base 802.1D bridge objects. It's deployed on 3Com SuperStack-series switches in enterprise LAN environments. Network engineers evaluating or troubleshooting this functionality can download the A3COM-SWITCHING-SYSTEMS-BRIDGE-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-SWITCHING-SYSTEMS-BRIDGE-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
- 3Com SuperStack switches
Monitoring Examples
An admin would poll a3ComSysBridgeAddressTableCount against a3ComSysBridgeAddressTableSize and a3ComSysBridgeAddressThreshold for each a3ComSysBridgeEntry in a3ComSysBridgeTable to detect a MAC table nearing exhaustion, which can cause unknown-unicast flooding. Checking a3ComSysBridgeAddressTablePeakCount over time shows historical peak load, while a3ComSysBridgeMode and a3ComSysBridgeBackbonePort reveal how the bridge instance is configured relative to the switch's backbone uplink.
What Can Be Monitored
- bridge/port count
- MAC forwarding table size and usage
- MAC table peak usage
- address table threshold
- bridge operating mode
- backbone port assignment

To remove an entry, set the instance of the a3ComSysBridgeVlanPortAddressType for the entry to invalid(2). | |
| INT a3ComSysBridgeVlanPortAddressIndex | 1.3.6.1.4.1.43.29.4.10.8.1.4 | INTEGER | read-only | The index of this address entry within the bridge vlan address table for the bridge identified by this entry. This index ranges from 1 to the corresponding value of a3ComSysBridgeAddressTableSize. |
| INT a3ComSysBridgeVlanPortAddressIsStatic | 1.3.6.1.4.1.43.29.4.10.8.1.7 | INTEGER | read-write | A value indicating whether this MAC address was statically configured or was dynamically learned. Note that isStatic(1) is only valid for set operations. |
| INT a3ComSysBridgeVlanPortAddressPortIndex | 1.3.6.1.4.1.43.29.4.10.8.1.3 | INTEGER | read-only | The index of the bridge vlan port identified by this entry, within the bridge vlan identified by this entry. |
| OCT a3ComSysBridgeVlanPortAddressRemoteAddress | 1.3.6.1.4.1.43.29.4.10.8.1.5 | OCTET STRING | read-write | The remote MAC address detected on the bridge vlan port identified by to this entry. Setting this object results in an attempt to create a new entry in the table. Since the value of a3ComSysBridgeVlanPortAddressIndex is determined automatically internal to the bridge vlan, a set is only successful if the index value specified for a3ComSysBridgeVlanPortAddressIndex is zero. A get-next using the values of a3ComSysBridgeVlanPortAddressTypeIndex and a3ComSysBridgeVlanPortAddressPortIndex can be used to determine the address index assigned to the newly added address entry. |
| INT a3ComSysBridgeVlanPortAddressStaticPort | 1.3.6.1.4.1.43.29.4.10.8.1.8 | INTEGER | read-only | If the corresponding value of the object a3ComSysBridgeVlanPortAddressIsStatic is isStatic(1), this object indicates the local bridge port index (as reported by a3ComSysBridgePortLocalIndex) for which this address MAC was statically configured. If the object a3ComSysBridgeVlanPortAddressIsStatic has the value isDynamic(2), the value of this object is 0. |
| a3ComSysBridgeVlanPortAddressTable | 1.3.6.1.4.1.43.29.4.10.8 | not-accessible | A list of vlan bridge port address information. A single entry exists in this list for each learned address, across all vlan bridge ports and all vlan bridges managed by this agent. | |
| INT a3ComSysBridgeVlanPortAddressType | 1.3.6.1.4.1.43.29.4.10.8.1.6 | INTEGER | read-write | This object, when read, always returns the value valid(1). Setting this object to invalid(2) will remove the corresponding address entry from the table. |
| INT a3ComSysBridgeVlanPortAddressVlanIndex | 1.3.6.1.4.1.43.29.4.10.8.1.2 | INTEGER | read-only | The index of the vlan identified by this entry, within the bridge identified by this entry. |
