err snmpd: IfIndex of an interface changed. Such interfaces will appear multiple times in IF-MIB

[togetinfo mail]

Hi,

When VRFs, VLANs and OSPF configurations are added, we see the below error
in syslog.
"err snmpd: IfIndex of an interface changed. Such interfaces will appear
multiple times in IF-MIB."
However, this does not appear everytime we make changes to interface. Why
is the message reported as an error?
Any way to get rid of this error message?

OS: Linux x86
net-snmp : 5.4.2.1

Thanks!

If you upgrade to a recent version you will see it at moust once.

you are lucky that I saw this message

Thanks for the reply!
But why is it reported with error severity?
Is it an error case?

It will surely confuse any network mangement application that one
interface can exist in the ifTable with two different indices.

I am not that much into the details of this part of the code
(agent/mibgroup/if-mib/data_access/interfaces.c) that I will suggest a
fix for the underlying problem)

Hi,
I see lot of discussion and patches related to this problem.
Not sure which one to use and the impacts.
Is there any solution available to resolve this?
