Description: Manages TP-Link switch Link Aggregation Group configuration, member ports, and LACP 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 TPLINK-LAG-MIB?

TPLINK-LAG-MIB is a TP-Link proprietary MIB configuring Link Aggregation Groups (LAG) and LACP on TP-Link managed switches. Its objects cover the maximum number of LAG entries and the global load-balance algorithm, a LAG table (index, type static/LACP, member ports, row status), and LACP-specific settings — system priority and a per-port table of admin key, port priority, LACP mode, and channel assignment. As a configuration MIB it lets an administrator confirm a LAG's member ports and load-balance method, and audit LACP priority/mode settings when a port isn't joining its expected aggregation group. It is deployed on TP-Link managed switches. Engineers can download the TPLINK-LAG-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TPLINK-LAG-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

TP-Link managed switches

Monitoring Examples

An administrator checks tpLacpPortPriority and tpLacpMode for a port failing to join its LAG, to confirm LACP settings match what the neighboring switch expects.

What Can Be Monitored

LAG membership and LACP configuration

OID symbolic	OID numeric	Type	Access	Description
tplinkLagMIB	1.3.6.1.4.1.11863.6.9			Private MIB for system time configuration.
tplinkLagMIBObjects	1.3.6.1.4.1.11863.6.9.1
tplinkLagMIBGlobalConfig	1.3.6.1.4.1.11863.6.9.1.1
INT tpLagMaxEntryNum	1.3.6.1.4.1.11863.6.9.1.1.1	INTEGER	read-only	This object indicates the max number of entries in the lag configuration table.
INT tpLagLoadBalance	1.3.6.1.4.1.11863.6.9.1.1.2	INTEGER	read-write	This object configures scope of Aggregate Arithmetic, which results in choosing a port to transfer the packets. mac-source-dest: When this option is selected, the Aggregate Arithmetic will apply to the source and destination MAC addresses of the packets. ip-source-dest: When this option is selected, the Aggregate Arithmetic will apply to the source and destination IP addresses of the packets.
tplinkLagTable	1.3.6.1.4.1.11863.6.9.1.2
tpLagTable	1.3.6.1.4.1.11863.6.9.1.2.3		not-accessible	A table that contains informatin about every static lag. LAG (Link Aggregation Group) is to combine a number of ports together to make a single high-bandwidth data path, which can highly extend the bandwidth. The bandwidth of the LAG is the sum of bandwidth of its member port.
tpLagEntry	1.3.6.1.4.1.11863.6.9.1.2.3.1		not-accessible	A list of information for every lag.
INT tpLagIndex	1.3.6.1.4.1.11863.6.9.1.2.3.1.1	INTEGER	read-only	This object indicates the index of the lag entry.
INT tpLagType	1.3.6.1.4.1.11863.6.9.1.2.3.1.2	INTEGER	read-create	This object indicates the type of the lag entry.
STR tpLagMember	1.3.6.1.4.1.11863.6.9.1.2.3.1.3	DisplayString	read-create	This object indicates how many ports are included in this lag. The maximum number of ports is eight for 'on' type lag, sixteen for 'active' or 'passive' type lag.
ROW tpLagRowStatus	1.3.6.1.4.1.11863.6.9.1.2.3.1.4	RowStatus	read-create
tplinkLagLacpManage	1.3.6.1.4.1.11863.6.9.1.3
INT tpLacpSystemPriority	1.3.6.1.4.1.11863.6.9.1.3.1	INTEGER	read-write	This object indicates the system priority of the lacp.
tpLacpTable	1.3.6.1.4.1.11863.6.9.1.3.2		not-accessible	A table that contains the lacp information of every port. LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad and enables the dynamic link aggregation and disaggregation by exchanging LACP packets with its partner. The switch can dynamically group similarly configured ports into a single logical link, which will highly extend the bandwidth and flexibly balance the load.
tpLacpEntry	1.3.6.1.4.1.11863.6.9.1.3.2.1		not-accessible	A list of lacp information for every port.
STR tpLacpPort	1.3.6.1.4.1.11863.6.9.1.3.2.1.1	DisplayString	read-only	This object indicates the port number.
INT tpLacpAdminKey	1.3.6.1.4.1.11863.6.9.1.3.2.1.2	INTEGER	read-only	This object indicates the Admin Key of the port. The member ports in a dynamic aggregation group must have the same Admin Key.
INT tpLacpPortPriority	1.3.6.1.4.1.11863.6.9.1.3.2.1.3	INTEGER	read-write	This object indicates the port priority of the port. This value determines the priority of the port to be selected as the dynamic aggregation group member. The port with smaller Port Priority will be considered as the preferred one. If the two port priorities are equal; the port with smaller port number is preferred.
INT tpLacpMode	1.3.6.1.4.1.11863.6.9.1.3.2.1.4	INTEGER	read-only	This object indicates the lacp mode of the port.
STR tpLacpChan	1.3.6.1.4.1.11863.6.9.1.3.2.1.5	DisplayString	read-only	This object indicates the lag number of the port.
