I just want to check is it normal to have 2 mac address response if I arping? In the attached screenshot the machine 192.168.123.201’s real MAC address is 00:15:f9:58:0b:87, however I noticed that the 5c:26:0a:fb:bc:87 (our Layer 3 switch MAC) is also replying. Is this normal? I am doing arping in my server which is in the Layer 2.
Our network set-up is L3 (Dell PowerConnect 8024) connected to 3 Dell PoweConnect 6248 (in a stack).
