Hello Carlos,

it could be normal behaviuor it should simply say that the return packet is process switched = sent to main cpu.

I remember another thread where the same sentence in the debug ip packet was shown in the process of translating a DHCP request for the ip helper-address command.

So if the ping is successful (you are getting responses) everything should be fine

Hope to help

Hello Giuseppe,

Yes, I am getting responses. The real problem is that my switch has another interface, e.g., and I try to ping from my MacBook and I never get responses...

Hello Carlos,

try to use debug ip icmp on the switch and from the MAC try to ping

before doing that :

verify that and are in the same IP subnet;

that is the GW for the

if you have ACL on L3 interfaces or you are doing NAT this can change the ping results:

what if from switch you do an extended ping to with source ?

Hope to help
