ICX-7450 show interface get 0 counters

[btspenser]

We have stacked ICX-7450G and ICX-7450GF with 0890 or 0895 sw release. We found the show interface ethernet x/x/1 ~ x/x/24 will show 0 counters after issued clear statistics ethernet x/x/25 ~x/x/48. The counters of ethernet x/x/1 ~ x/x/24 will come back after issue clear statistics ethernet x/x/1 ~ x/x/24. However, the counters of ethernet x/x/25 ~ x/x/48 will change to 0. Is there any solution for this problem?

(1)Below image show interface ethernet 2/1/47 input/output rates are non zero.

(2) Below image show interface ethernet 2/2/1 input/output rates are zero.

(3) Below image show interface ethernet 2/2/1 input/output rates change to non-zero after issue clear statistics ethernet 2/2/1

(4)However, the interface ethernet 2/1/47 input/output rates changes to zero.

(5) Below image show interface ethernet 2/1/47 input/output rates change back to non-zero after issue clear statistics ethernet 2/1/47

(6)Unfortunately, below image show interface ethernet 2/2/1 input/output rates change back to zero after issue clear statistics ethernet 2/1/47.

Hi Btspenser

Ack and Noted. Thanks for sharing the details. 

Could you help us with below details

• What is the current version running on the switch ?
• What if you reset counter values on other ports like 1/1/1 or any random port on the switch apart from the one in the example shared in the post ? Do they also create a problem with other random ports ? 
• Are only port 2/1/47 and 2/2/1 showing the issue ?

Could you also help us with more information on end devices connected to this switch , and I also wanted you to test with "show statistics e <port number>" command when you try to test the above senario. 

Let me know your observation. 

Thanks

• What is the current version running on the switch ? 

         08.0.95g

• What if you reset counter values on other ports like 1/1/1 or any random port on the switch apart from the one in the example shared in the post ? Do they also create a problem with other random ports ? This issue happened with port group.

         Some switches happen between 1/1/1-1/1/24 and 1/1/25-1/1/48. This switch happens between 2/1/25-2/1/48 and 2/2/1-2/2/2. The counters of 2/2/1-2/2/2 change to 0 after issue clear statistics on  2/1/25-2/1/48.

• Below are the images of 2/1/25, 2/1/47, 2/2/1, 2/2/2, 2/2/3, 2/2/4 before clear statistics on ethernet 2/2/1

• Below are the images of 2/1/25, 2/1/47, 2/2/1, 2/2/2, 2/2/3, 2/2/4 after clear statistics on ethernet 2/2/1

Hi Btspenser

Ack and Thanks for sharing the details.

Would you be able to upgrade one of the switch in the network which is showing the issue to 8095m version. Try to test it on access switches with less usage. 

Before you test take a back up of configuration using "show run" command.
