MultiPod Misery

Hi,

 

I'm currently in the process of moving L3s down into ACI for the 2nd pod in my network. Unfortunately, I have done a few test BDs and I have reports of absolutely horrendous performance after the L3 has been put in ACI. Notable, file transfers and replication basically cease immediately. That said, ICMP and connectivity still works... This is true on Inter-pod, inter-VRF, inter-BD, as well as inter-pod, intra-VRF and intra-BD.

 

 

 

I've checked non-ACI devices for speed, interface drops, MTU and all looks fine

 

I've also completed some basic pcaps on the IPNs (9Ks) but the output only goes as deep as the first IP header. I do see lots of UDP (VXLAN I guess) as well as one TCP flow, which sees a far amount of retransmissions, and lost segments.

 

Any Ninjas out there fancy pointing me in an direction?

 

Btw, due to the nature of the business I am in, to remain compliant, I have no third party applications anywhere near this network i.e Wireshark & Pingplotter/
