Category: Vendor: 3Com

Description: Manages traffic filtering and ACL configuration on 3Com SuperStack switches, providing packet filter definitions and per-port application settings.

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-SWITCHING-SYSTEMS-FILTER-MIB?

This is a 3Com private MIB for SuperStack-family switching systems, managing traffic filtering and access control list configuration including named address groups and per-port filter application. It exposes tables for filter address groups (with name, bridge mask, and status) and address entries within those groups, along with counters and next-available-index objects for managing the filter configuration namespace. Its monitoring value is around filter/ACL configuration state—confirming which address groups exist, their bridge masks and row status, and which addresses are members—useful for auditing security filtering policy, though it does not expose hardware sensor data. It is a standalone 3Com enterprise MIB within the broader switchingSystemsMibs private enterprise tree, without evident dependency on external standard MIBs. It would be deployed on 3Com SuperStack switches in enterprise LAN environments requiring MAC/address-based traffic filtering, where the A3COM-SWITCHING-SYSTEMS-FILTER-MIB MIB gives administrators SNMP visibility into filter group configuration.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-SWITCHING-SYSTEMS-FILTER-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 switch

Monitoring Examples

An operator would walk a3ComFilterAddressGroupTable, keyed by a3ComFilterAddressGroupId, to confirm the a3ComFilterAddressGroupName and a3ComFilterAddressGroupStatus of each configured filter group, verifying it is active and correctly named. The a3ComFilterAddressGroupBridgeMask and a3ComFilterAddressGroupMaskId reveal how addresses in the group are matched, while a3ComFilterAddressTable lists the individual addresses belonging to each group—an unexpected or missing entry here would indicate a filtering policy gap. a3ComFilterAddressGroupCount and a3ComFilterAddressGroupNextAvailableIndex help an admin track how much of the filter table capacity is in use.

What Can Be Monitored

  • filter address group name/status
  • bridge mask per filter group
  • addresses within a filter group
  • filter group count/capacity
