Port 1 Status Critical - Interface A1 (index 1) is down.

[dlukinski]

Hello XI Support

After replacing switch (retaining SNMP configurations), we've started receiving "Interface A1 (index 1) is down" on Port 1 status.
We-created Port check with the Wizard, but same results. Something Nagios does not like about this new switch (what could it be?)

Thank you

Is the switch the same EXACT model as the one before? Can you show us the service definition for this one in question?

Are the rest of the ports working without issues?

Hi,

We just had a very similar situation - replaced a switch and retained snmp settings and made sure ACL had XI server IP. Everything looked fine. The issue was the v3 password(auth). We had to manually reset it and all worked after that. Hope this helps.

Thanks @brdr!

@dlukinski - let us know if this solution helps, as well as provide a bit of information to my previous response.

Also, another thing that may change is the ifIndex (other stuff may have changed as well depending on if you have the exact same hardware revisions/firmware).

You should be able to find the information with an snmpwalk:

Code: Select all

snmpwalk -v 2c -c community 192.168.XXX.XXX:161 mib-2.interfaces

What if I had created new check with SNMPwalk - still wrong

v3 authentication is not used by me / Bandwidth check works w/o it.

Please post the full output of the snmpwalk.
