Dell N4032f Interfaces Error and Drops packets

Question

Hi, I have Two Switches Dell N4032f configured as a Stack. I have a major problem with all connected interfaces I get many error and drops on each connected interface. Ex: Some of Interface counters: ``` console#show interfaces counters Te2/0/22 Port InTotalPkts InUcastPkts InMcastPkts InBcastPkts --------- ---------------- ---------------- ---------------- ---------------- Te2/0/22 14749843 13896754 812845 40244 Port OutTotalPkts OutUcastPkts OutMcastPkts OutBcastPkts --------- ---------------- ---------------- ---------------- ---------------- Te2/0/22 2001380 278646 1620873 101861 FCS Errors: ................................... 0 Single Collision Frames: ...................... 0 Late Collisions: .............................. 0 Excessive Collisions: ......................... 0 Multiple Collisions: .......................... 0 Received packets dropped > MTU: ............... 128265 Transmitted oversized packets: ................ 0 Internal MAC Rx Errors: ....................... 128265 Received Pause Frames: ........................ 0 Transmitted Pause Frames: ..................... 0 Receive Packets Discarded: .................... 0 Transmit Packets Discarded: ................... 0 Received PFC Frames: .......................... 0 Transmitted PFC Frames: ....................... 0 console#show interfaces counters Te1/0/21 Port InTotalPkts InUcastPkts InMcastPkts InBcastPkts --------- ---------------- ---------------- ---------------- ---------------- Te1/0/21 13057417 12178112 848297 31008 Port OutTotalPkts OutUcastPkts OutMcastPkts OutBcastPkts --------- ---------------- ---------------- ---------------- ---------------- Te1/0/21 7222759 5529048 1584330 109381 FCS Errors: ................................... 306372 Single Collision Frames: ...................... 0 Late Collisions: .............................. 0 Excessive Collisions: ......................... 0 Multiple Collisions: .......................... 0 Received packets dropped > MTU: ............... 124951 Transmitted oversized packets: ................ 0 Internal MAC Rx Errors: ....................... 476724 Received Pause Frames: ........................ 0 Transmitted Pause Frames: ..................... 0 Receive Packets Discarded: .................... 0 Transmit Packets Discarded: ................... 0 Received PFC Frames: .......................... 0 Transmitted PFC Frames: ....................... 0 console# ``` Switch Version and stack: ``` console#show switch Management Standby Preconfig Plugged-in Switch Code SW Status Status Model ID Model ID Status Version --- ---------- --------- ------------- ------------- ------------- ----------- 1 Mgmt Sw N4032F N4032F OK 6.5.3.7 2 Stack Mbr Oper Stby N4032F N4032F OK 6.5.3.7 ``` All the cables its Dell Optic cables Thanks, Diab

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

Hi,

Thanks for your response,

Yes, I updated the switches to latest: "6.5.3.7"

unit active backup current-active next-active
---- ----------- ----------- -------------- --------------
1 6.5.3.7 6.5.1.3 6.5.3.7 6.5.3.7
2 6.5.3.7 6.5.1.3 6.5.3.7 6.5.3.7

Most (90%) from the cables are Dell DAC cables, and I have 4 Transceivers also from Dell with Dell Logo (I buy Everything form same Dell Dealer and we did double check and everything is Dell Recommendation).

Hi,

Thanks for your response,

Yes, I Updated the switches (Stack) to lates: 6.5.3.7

unit active backup current-active next-active
---- ----------- ----------- -------------- --------------
1 6.5.3.7 6.5.1.3 6.5.3.7 6.5.3.7
2 6.5.3.7 6.5.1.3 6.5.3.7 6.5.3.7

Most of the cables (90%) are Dell DAC Cables, and I have 4 transceivers on each switch it's also Dell with Dell Logo.
We also did double check with my Dell Dealer and they confirmed that all my hardware on those switches is Dell Recommendation,

Please note that all the hardware in my Datacenter is Dell excepting the firewalls (Fortigate).
1. Servers are Dell R730 (New)
2. Switches N4032f (New)
3. Storages are Dell SVC 3020 (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: ....................... 167380

The 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
Transmitted oversized packets: ................ 0
Internal MAC Rx Errors: ....................... 128265

Thanks,
