Do we have to modify the type of network or network adapter in virtual box, this is weird, i try to capture the traffic on the link and the two devices keep arping each other endlessly

Hey there!

Please verify if you have installed the newest license for CE1200 on eNSP.

Also, please confirm if there is an ACL that may be denying the ICMP packets. I suggest you run the CMD 'display ACL all' to confirm if it is matchign with some ACL.

I test on eNSP too, it work. Please delete close eNSP and restart again to test. The attachment is my test topology.
