ARP
- Check the "ARP requests" box.
- Send a ping from st1 to the address "10.0.0.4" and watch:
- Station st1 does not have the MAC address of the interface that has to be reached with this IP address: thus, it sends an ARP request.
- The interfaces of stations st2 and st3 do not answer this request.
- St4's interface answers this request.
- Once it gets the MAC address, st1 sends the ICMP request (ping).
- Send the same ping again: the information has been stored, so no ARP request needs to be made anymore.
- Choose "Tables", and "ARP cache" in st1’s pop-up menu: this information is stored in the cache.
- Choose "Clear ARP cache" in the pop-up menu. Send the ping one again: protocol ARP is used again.
