What is l2LearnedFlowEntries?
This counts the total number of learned Flow entries, where each entry is a unique VLAN ID, source MAC, and destination MAC 3-tuple. Admins use it to see how many distinct traffic flows the switch's Layer 2 engine is tracking, a finer-grained count than the plain MAC total in l2LearnedMacEntries.
