Stop process pak for forus packet

My interface has IP 172.16.1.62 and I ping a device on the same subnet with IP 172.16.1.1 and I get with debug on the response Stop process pak for forus packet. Any idea what is happening?

Re: Stop process pak for forus packet

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

Re: Stop process pak for forus packet

Hello Giuseppe,

Yes, I am getting responses. The real problem is that my switch has another interface, e.g., 158.97.80.62 and I try to ping 172.16.1.1 from my MacBook 158.97.80.30 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 158.97.80.62 and 158.97.80.30 are in the same IP subnet;

that 158.97.80.62 is the GW for the 158.97.80.30

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 158.97.80.30 with source 172.16.1.1 ?

Hope to help

Giuseppe
