CRS310/309 through CHR - ping packet loss

RouterOS General
1

I’m setting up a configuration where CHR is running in a VM on a Proxmox host that is funneling all internet access into my network. So the host has one connection to a dual WAN switch and the other the the CRS310-8G+2S+. I also have a CRS309-1G-8S+ that is bridged via SFP+ to the first bridge port of the 310. (all are running ROS 7.15.3). As I was setting up NAT and Routes I checked a few IPs via ping and noticed that I was getting a LOT of packet loss on the two hardware switches.

[admin@Mgr CHR] > ping 1.1.1.1
[...]
    sent=20 received=20 packet-loss=0% min-rtt=17ms558us avg-rtt=18ms631us 
   max-rtt=20ms152us

[admin@2.5GSwitch] > ping 1.1.1.1
[...]
    sent=20 received=12 packet-loss=40% min-rtt=41ms944us avg-rtt=49ms898us max-rtt=59ms882us

[admin@10G Switch] > ping 1.1.1.1
[...]
    sent=20 received=5 packet-loss=75% min-rtt=40ms323us avg-rtt=51ms188us 
   max-rtt=77ms134us

As can be seen, the CHR is fine while the two hardware switches are not. I was hoping someone here with more experience would be able to shed some light on how or why this might be happening. Thanks!

Disregard - fixed it on my own by simply resetting both switches and reconfiguring step-by-step. I missed/messed-up something somewhere along the line but now things are in order.

Would be interesting if you got an old backup available to compare what the difference became to your working config?
