How to reset counters on interfaces: error, dropped, frame
To understand if there is still a problem.

The easiest way is to reboot if that is an option. Otherwise check this SK How to reset interface counters

Reboot not required!

You'll have to reload the driver on this NIC

[Timothy_Hall · Accepted solution]

You can most certainly reset interface counters via the steps in sk61500.  Just be aware that reloading a NIC device driver will cause an outage on *all* individual interfaces utilizing that particular driver, including no doubt (in true Murphy's Law fashion) the interface you are currently using for your SSH control connection into the firewall itself.  Careful! 

Kind of like copy/pasting ACL updates on a Cisco and your SSH session freezes up permanently, sparking a panicked sprint to the console...oops.

I am not able to see that sk sk61500. Do you have any idea why it is so?

Either they removed it or its internal sk now.

Just tested these expert mode commands on eth1 interface using vmxnet3 driver, and it worked to reset the counters for that interface:

ifconfig eth1 down;ifconfig eth1 up

This should also work:

ifdown eth1;ifup eth1

Can't vouch for whether the above commands will work with igb/ixgbe/mlx* drivers, if they don't try these WHICH WILL CAUSE AN OUTAGE ON ALL INTERFACES USING THE IGB DRIVER in this example, use at your own risk:

modprobe -r igb; modprobe igb

Then you will need to manually re-up all relevant igb-based interfaces like this to get them working again:

ifup eth0

ifup eth1

ifup eth2

etc....

sk61500 is no longer available for two reasons:

• It's marked Internal
• It's marked "old" which means it's also not on the new SupportCenter

However, @Timothy_Hall describes the procedure in that SK.
