that specific address as a unicast if it is not present in
the table then the address resolution protocol broadcast
that address and when it get a correct reply from a port it
then add that port to there mac address table so it mean

A PC in an Ethernet network can communicate with another
PC, if only it knows the Ethernet address (MAC address) of
that PC. Address Resolution Protocol (ARP) is a network
protocol uses to translate a PC’s IP address to physical
(hardware) address. From OSI model point of view, ARP
belongs to the OSI data link layer (Layer 2).

Packet from switch and if I check RJ45 (with LAN tester)from PC side the packet and 8 pin wire is working fine and after that process of LAN tester I plug RJ 45 in PC now PC start recd/ send packets what is the problem I don’t understand even client side no virus found RJ45 is ok and switch has no problem bcoz other PC is working fine Cable (cat 5 ) is also fine bcoz I didn’t crimp again just check in LAN tester and start working fine. Plz any one solve this matter. And after lan tester process pc is working fine and after 2 or 3 hour it again start same problem and again same process lan tester I have used
