I had the same problem...the configuration ran fine with ping/ssh/traceroute if I used Cisco virtual L2 switch but as soon as I swapped out the switch for Aruba OS CX simulator 10.07, I still had ping but ssh and traceroute were having issues. I had the same problem on 2 different eve-ng community edition versions 5.0.1-10 and 2.0.3-112. My three target types (all having problems with Aruba but not Cisco) were VPC, Infoblox, alpine Linux. Eventually, I read a note about Aruba + vSphere and setting the targets to e1000 but that didn't help every node, esp not Infoblox 8.4.8 or 8.6.1. Once I shut off the Aruba and set THE ARUBA INSTANCES' QEMU NIC setting from virtio-net-pci to e1000, then restarted it, every node worked as expected. Now that I have it running, I am sticking with eve-ng community 5.0.1-10 (had to build it using an ISO, not OVA) on vSphere 7.0.3(?) with Arubos CX 10.07 to continue my training.. I hope this note helps someone else.
Regards,
David

Dear administrators, please keep this reply Pinned in the forum. I was about to lose my mind, I was having FTP and SSH connections timeout, until I read this gentleman's reply... I am very happy to keep Aruba in my topology.

I think I figured it out; if you edit the CentOS node's properties to have an e1000 NIC instead of the default virtio-net-pci NIC, all the TCP traffic should start working as desired
That was a real mind-blow at first; last night I was digging through firewalld, thinking I had a duplicate MAC somewhere, or who knows what. But the fact that my Windows hosts were working 100% made no sense.
Sure enough, after thinking about it a little more and comparing the Win hosts to my networksecuritytoolkit.org Fedora 32 build, the NIC type jumped out at me, and I'm happy to be keeping the ArubaOS-CX in my eve-ng topology!

Hello,
I started learning Aruba devices configuration and I have problem with traffic between two centos nodes passing through ArubaCX in EVE-NG environment. When I ping from centos1 to centos2 it works but when I tried to ssh from one to another device there is a problem. Wiereshark sees "TCP Retransmission" packets and centos node returns "Connection timeout".
When I swap Aruba with EVE-NG built in bridge network it just works. I worked with Cisco IOSvL2 int the past and i didn't have problems with that to.
There is a bug in EVE-NG/ArubaCX or I need to config something?
I have tiny Cisco experience and with Aruba I started today.
My topology for now is very simple:
centos1 - ArubaCX - centos2
ArubaCX config:
...
interface 1/1/2
no shutdown
no routing
vlan access 1
interface 1/1/3
no shutdown
no routing
vlan access 1
...
I'll deploy ArubaCX in vmware tommorow and i'll check this but maybe in the meantime someone have any idea what is going on...
