Title: Ierrs & Oerrs are way off on ax0
Post by: Evert on November 20, 2024, 09:40:46 AM
Hi,

When I run
Code Select
netstat -i on our DEC2750 v2 unit, I get the following values on ax0:
Code Select
Ierrs: 18446744073709551598
Oerrs: 18446744073709551538
Both of these values are ridiculously high, and suspiciously close to 2^64.

The other interfaces report valid values, as far as I can tell.

How do I get the real Ierrs & Oerrs values for ax0?

Is that interface a parent to, VLAN, LAGG or any overlay?

S.

It is indeed. Does that mess with Ierrs/Oerrs?

Yes it does,

This is one of the most common problems that it causes if you have parent interface assigned.

Go to Interfaces ‣ Assignments and assign the new VLAN interfaces. The parent interface should stay unassigned. In rare cases, the parent interface can be assigned without a network configuration, to allow manual link speed overrides.
