1. Servers are Dell R730 (New)
2. Switches N4032f (New)

4. Firewalls Fortigates 500E (New)
5. Cables Dell DAC - Connect between the servers and storages and Firewalls to the two Switches.
6. Dell Transceivers (with Dell logo "New"): Connect the switches to our Hosting Provider.I have the same issue or packet loss in al the connected interfaces:
Received packets dropped > MTU: ............... 167380
Transmitted oversized packets: ................ 27478
Internal MAC Rx Errors: ....................... 167380The Transceivers interfaces that connected the switches I(our Backbone) to our Hosting Provider its have only "Received packets dropped > MTU" & "Internal MAC Rx Errors" without "Transmitted oversized packets" like all other interfaces.
Received packets dropped > MTU: ............... 128265

Hi,
Is the firmware up to date? Are you using Dell transceivers?
