MAC address table and frame forwarding on Layer 2 switches - question about when two computers are connected via hub to same switch port
A hub simply repeats electric signals received on a one interface out of all other interfaces. So device 0F, as well as the switch, will receive the frame.
In that case the switch will not forward the ...

Show LLDP neighbors history
No, not on Aruba/HPE switches. You'd need to have debug logged LLDP events (creating quite a mess likely) or polled the neighbors via SNMP. Otherwise, past information is lost.

How Does A Layer 2 Switch Differentiate Between Different Networks?
Should not all nodes can communicate with each other based on the fact
that they all exist in a MAC-based world.
The MAC layer of both Ethernet (802.3) and Wi-Fi (802.11) both use 48-bit addresses, ...

Switch stack with only one
Using a single port for stacking isn't possible with N1000 switches.
NOTE: N1124T-ON/N1148T-ON/N1124P-ON/N1148P-ON/N1500 10G SFP+ ports may
only be configured as stacking in adjacent pairs, e.g. Te1/...
