Description: Manages MAC address table entries, aging time, and static MAC bindings on H3C Layer 2 switches.

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 HH3C-LswMAM-MIB?

HH3C-LswMAM-MIB is an H3C-specific MIB for the MAC Address Management (MAM) feature on H3C Layer 2 switch platforms. It exposes configuration and status data for the switch's MAC address table, including learned dynamic entries, statically configured bindings, and aging-time settings. Its monitoring value lies in tracking the software state of the switch's forwarding plane: the size and churn of the MAC table, aging behavior, and static entry consistency, which help detect MAC flapping, table exhaustion, or unauthorized device attachment. It complements the standard BRIDGE-MIB (dot1dTpFdbTable) by adding H3C-specific management controls not covered by that IETF standard. It is used on H3C access and aggregation-layer Ethernet switches in enterprise and campus LAN deployments. Engineers can download the HH3C-LswMAM-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-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 sample object names were available in the provided source, so specific OIDs cannot be quoted, but a typical use is polling the switch's MAC address table size and per-port learned-entry counts to detect a sudden spike suggesting a MAC flooding attack or a loop. Comparing configured aging time against actual entry churn also helps confirm the table is aging out stale devices as expected rather than filling up with stale entries.

What Can Be Monitored

MAC address table size
dynamic vs static entry counts
MAC aging time
per-port learned MAC count

NUM hh3cdot1qTpFdbSetPort	1.3.6.1.4.1.25506.8.35.3.2.1.2	InterfaceIndex	read-write	Interface index corresponding to the MAC address
INT hh3cdot1qTpFdbSetStatus	1.3.6.1.4.1.25506.8.35.3.2.1.3	INTEGER	read-write	State corresponding to the MAC address
INT hh3cdot1qTpFdbSetOperate	1.3.6.1.4.1.25506.8.35.3.2.1.4	INTEGER	read-write	Add or delete an MAC address. Read operation not supported.
hh3cdot1qTpFdbGroupSetTable	1.3.6.1.4.1.25506.8.35.3.3		not-accessible	Multistcast address setting table, whose maximal row number is dynamically changed by the influence of IGSP. When reaching the upper limit of the table, no more row could be added, then an error will be returned.
hh3cdot1qTpFdbGroupSetEntry	1.3.6.1.4.1.25506.8.35.3.3.1		not-accessible	Multicast address setting table entry.

POR hh3cdot1qTpFdbGroupSetPort	1.3.6.1.4.1.25506.8.35.3.3.1.2	PortList	read-write	The complete set of ports, in this VLAN, to which frames destined to this Multicast MAC address are currently being explicitly forwarded. This does not include ports for which this address is only implicitly forwarded.
INT hh3cdot1qTpFdbGroupSetOperate	1.3.6.1.4.1.25506.8.35.3.3.1.3	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 hh3cdot1qTpFdbGroupSetPort is optional.
