tnSysPortMacLearningState
Module: TN-MGMT-MIB
OID (symbolic): TN-MGMT-MIB::tnSysPortMacLearningState
OID (numeric): 1.3.6.1.4.1.868.2.5.3.1.1.4.1.1.1
Node type: OBJECT-TYPE
Type: PortList
Access: read-write
Description: This indicates the port's state on MAC learning. If the bit corresponding to the port is set, then learning is enabled else it is disabled.
What is tnSysPortMacLearningState?
This is a bitmask that shows which switch ports are learning MAC addresses from incoming frames. When learning is on, the switch notes which devices are on which ports; when off, the port is blocked or read-only. A network admin would enable learning on trunk ports but disable it on secure edge ports to prevent spoofing.
