Hey all, Got a Cisco 9500 as a new core switch. Went to cable it over this evening and ran into an issue where it wouldn't pass L3 traffic, or seemingly send or respond to ARPs (I do see some entries, but nothing from hosts I'm generating traffic fro...
No problem, Looks like the 9500 will have more entropy hashing on the 5-tuple, I'd config the 9400 to match the 9500 hash load-balance as of now it just hashes based on d-mac and d-ip which might be causing what you're seeing. The more tuples we matc...
Hello, It may just be the load balancing algorithm pinning the rx traffic to the other link. The "port-channel load-balance ?" In global config should show you the available load balancing options. See here for relevant commands to configure the hash...

There's been some good suggestions so far. Alternatively do you have any config that would drop the traffic I.e. arp inspection. Can you provide output of "show int trunk" so we can see the forwarding status of the interface? For the purpose of troub...
Hi Sean, Are you able to show us port configs, as well as anything that would effect this i.e. dhcp snooping, arp inspection? If you run debug arp on your core switch are you seeing the GARP ingress?
