If there are no ARP entries on the switch then it is a sign that the switch management interface has not been used to access other IP addresses.A gathering place for CCNA's, or those looking to obtain their CCNA!

Do not post questions you saw on the exam. Cisco Packet Tracer et GNS3 sont deux outils de simulation de rseau populaires, mais vous le savez dj. Remembering that the ARP table is the result of routing activity we can understand that if you have used the management interface of the switch to access network resources within its own subnet (ping in its own subnet is a good example) there there would be entries in the ARP table of the switch. The switch will certainly have a mac address table and it may have an ARP table. It may be that you need to session to the switch to see its mac address table. But you may not be able to see the switch mac address table from the router command line. If your router has a switch module then the switch module will build a MAC address table. ![]() So the MAC address table is the result of switching activity and the ARP table is the result of routing activity. ![]() The MAC address table is the result of layer 2 activity and is built as layer 2 interfaces receive a frame and discover the source MAC address of the frame. The ARP table is the result of layer 3 activity and is built as layer 3 interfaces look for and find the MAC address associated with an IP address. To answer this let us start by understanding the 2 things (ARP table, and MAC address table) and how they are used and how they are different. ![]() What is wrong with this? Is it because of GNS3? But I can't see mac-address-table from router and arp table from switch. Question) So, when I do "show ?" i can see both "arp" and "mac-address-table" supported from both router and switch.
