Description: Manages MAC address table entries, aging timers, and static MAC bindings on H3C LAN switch platforms.

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-LswMAM-MIB?

A3COM-HUAWEI-LswMAM-MIB is an H3C/3Com proprietary SNMP module for LAN switch platforms that manages the MAC address table, covering learned MAC entries, aging timers, and statically configured MAC-to-port bindings. It would typically expose per-port MAC entry counts, table aging-time configuration, and static binding entries used for port security. As a Layer-2 forwarding-table MIB it supports monitoring of the switch's forwarding-plane software state, for example detecting when a MAC table is approaching capacity or when unexpected MAC entries appear on a port, rather than physical component health. Dependency: it parallels the standard BRIDGE-MIB forwarding-database concept but is implemented as an H3C-specific extension with additional management controls. Deployment is on H3C LAN switches at the access or aggregation layer where MAC-table visibility and static binding/port-security features are used, and network teams can download the A3COM-HUAWEI-LswMAM-MIB file to load it into their MIB browser.

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

No object or table names were available for this module in the sampled source, since both module_desc and sample_objects are empty, so a concrete OID-level example is not given here to avoid inventing identifiers. In general such a MIB would be polled for MAC table entry counts and aging timer settings, and an unusually high growth rate in dynamic MAC entries on a single port could indicate a MAC-flooding condition or a misconfigured trunk.

What Can Be Monitored

MAC address table entry count
MAC aging timer configuration
static MAC-to-port bindings

INT hwdot1qTpFdbGroupSetOperate	1.3.6.1.4.1.43.45.1.2.23.1.3.3.1.3	INTEGER	read-write	Add or delete a Multicast MAC address. Read operation is meaningless. When adding a Multicast MAC address, it is required to provide MacAddress, VLAN and PortList all. For deleting operation, MacAddress and VLAN must be provided, but hwdot1qTpFdbGroupSetPort is optional.
