Not able to ping the google.com from controller CLI
What is the reason for not able to ping google.com from controller ?
This behavior is because of ICMP payload mismatch. I.E when we send ICMP Echo request it contain bigger bytes but in Echo reply that data is truncated and sent with lesser size.
As per RFC RFC 1122 , section 220.127.116.11 the data in request and reply should match.
Hence Aruba checks for the entire data in the icmp reply and drops the ping reply as it does not have all the data.
Below is the ICMP ECHO Request packet where we can see the 1104 Bits.
Below is the ICMP ECHO Reply packet where we can see the 912 Bits.
