Description: Manages TP-Link switch port mirroring source and destination port configuration for traffic analysis.

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-PORTMIRROR-MIB?

TPLINK-PORTMIRROR-MIB is a TP-Link private MIB for configuring port mirroring, a diagnostic feature that copies traffic from one or more source ports to a designated destination port for analysis with a network sniffer or monitoring tool. It exposes configuration objects defining which source port(s) and traffic direction are mirrored and which destination port receives the copied traffic. Its monitoring value is purely configuration status - confirming which mirroring sessions are currently configured and active - it does not itself produce hardware or performance telemetry, though it is the tool an operator uses to enable deeper packet-level troubleshooting of hardware/software issues elsewhere. It has no dependency beyond the switch's own standard ifIndex convention to identify source/destination ports. It is deployed on TP-Link managed switches whenever an administrator needs to capture and analyze live traffic for troubleshooting. Engineers can download the TPLINK-PORTMIRROR-MIB file directly to load it into their MIB browser.

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

Monitoring Examples

Specific table/object names were not present in the provided sample, so a concrete polling example is not grounded in real identifiers; based on the module description, an administrator would check the configured port mirroring session to confirm the correct source port(s) and traffic direction are being copied to the intended destination/monitor port before attaching a packet analyzer.

What Can Be Monitored

configured mirror source port(s)
mirrored traffic direction
destination/monitor port assignment

INT tpPortMirrorSession	1.3.6.1.4.1.11863.6.11.1.1.1.1	INTEGER	read-only	This object indicates the session number of the mirror group.
OCT tpPortMirrorDestination	1.3.6.1.4.1.11863.6.11.1.1.1.2	OCTET STRING	read-write	This object indicates a destination port which monitors specified ports on the switch, should be given as 1/0/1. Note: The member of LAG cannot be assigned as a destination port.
OCT tpPortMirrorIngressSource	1.3.6.1.4.1.11863.6.11.1.1.1.3	OCTET STRING	read-write	This object indicates a list of the source ports. Any packets received from these ports will be copyed to the assigned destination port. This should be given as 1/0/1,1/0/2-12. Note: The ports in other sessions and destination port can't add to this list.
OCT tpPortMirrorEgressSource	1.3.6.1.4.1.11863.6.11.1.1.1.4	OCTET STRING	read-write	This object indicates a list of the source ports. Any packets sended out from these ports will be copyed to the assigned destination ports.This should be given as 1/0/1,1/0/2-12. Note: The ports in other sessions and destination port can't add to this list.
OCT tpPortMirrorBothSource	1.3.6.1.4.1.11863.6.11.1.1.1.5	OCTET STRING	read-write	This object indicates a list of the source ports. Any packets received or sended out from these ports will be copyed to the assigned destination ports.This should be given as 1/0/1,1/0/2-12. Note: The ports in other sessions and destination port can't add to this list.
INT tpPortMirrorSessionState	1.3.6.1.4.1.11863.6.11.1.1.1.6	INTEGER	read-write	This object indicates the state of mirror session.If a session has been assigned both destination port and source ports, then the value of this object changes to active(2). Otherwise the value of this object is to be negative(1). When the value of this object is assigned to clear(3), then the configuration of this session will be cleared, and the state changes to negative(1). Be aware of that only clear(3) can be assigned to this object.
