Hello teams,
we have a cluster of Fortigate. Each device is connected with LACP on 2 Nexus in VPC (3524-10GX). On the other side, they are connected with LACP on 1 Catalyst C4500.
On the Nexus, we have ESX servers, 3 on side A, 2 on side B, connected on etherchannel with vpc. From the admin desktop, we can reach these ESX with a simple ping,there is no problems.
But, when we tried to reach them on https, we have a lot of loss. So, we tried to ping them with the option " ping -l 1500", and we saw a lot of packets loss.
On the Nexus, if we change the speed of Port Channel 252 (look the attachment file) to 100MB FD, we have no problemeanymore. We used SFP copper from NExus side to connect the Fortigates, but with fiber SFP the problem persist.
For information, the lacp and port channel returns no errors, CRC, etc...
We tried to do the lacp on single Nexus, same problem and on a single Catalyst C9300, no problem.
So, is there any issues between Fortigate 100F hardware and Cisco Nexus ?
Regards
