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?

Hi btspenser ,

Thank you for posting you query !!!

I comprehend that the counter on ports x/x/1-x/x/24 will come back even after issue clear statistic command .

Could you please let us know in counters which values are increasing if it is crc/errors are increasing then this could be a hardware issue and you can follow the below plan of action :

If the crc are increasing then I am suspecting this could be a layer one issue i.e. physical layer so I would suggest you to try changing the cable/sfp/port with a good know working one in order to isolate the issue and then test weather the crc counters are increasing or not .

Moving Forward If this issue is not resolved , Please log a ticket with the below link so that we will help further

I hope this information helps you

Hi Btspenser

Thank you for reaching us.

Adding to the post from the problem statement below are the details I could understand and I suppose your concern is more with the clear statistics command itself

When you run "clear statistics ethernet 1/1/25 to 1/1/48" you see that the counter value of ports 1/1/1 to 1/1/24 are showing 0
When you run "clear statistics ethernet 1/1/1 to 1/1/24" you start seeing values in the counter.

Could you help us with below details

When you say counter value of ports 1/1/1 to 1/1/24 is showing 0 does it mean when you execute command "clear statistics ethernet 1/1/25 to 1/1/48" though you have devices connected on the ports from 1/1/1 to 1/1/24 the counter value shows "0" but link is "Up" or you mean that even counters "1/1/1 to 1/1/24" are also reset to 0 ?
Are end devices connected on all ports for this unit ?
Could you help us with current switch version ?

If "clear statistics " is executed all interfaces stats will be cleared

If "clear statistics ethernet <port number>" is executed then only the port stats will be cleared

Below is the link about more details about this command:

I hope the above details helps

(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.

(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

btspenser

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.
