SNMP MIBs missing #5889

Open vaibhavhd opened 3 years ago

vaibhavhd commented 3 years ago

Description

MIB missing errors are consistently logged in /var/log/quagga/bgpd.log. I think this is common in every platform ( I checked 6100 and DX010).

The SNMP docker in .201911 image does not have these MIBs present in /usr/share/mibs/ The missing MIBs are listed in miblist.txt. The missing MIBs are present at https://github.com/net-snmp/net-snmp/tree/V5-7-patches/mibs but somehow SONiC image does not include them.

Steps to reproduce the issue:

  1. Step inside snmp container.
  2. Check dir /usr/share/snmp/mibs/
  3. Some MIBs mentioned in milist.txt are absent in the dir.

Describe the results you received:

Missing MIBs errors in bgpd.log

Describe the results you expected:

SNMP Mibs that are listed in miblist.txt should be found (ideally).

qiluo-msft commented 3 years ago

Even the 'the results you expected' is met, bgp and snmp are isolated containers, so bgpd still has no visibilities on that folder.

What is the real impact other than the ERR logs?

vaibhavhd commented 3 years ago

I see. My assumption was that the MIBs listed in miblist.txt have some purpose. I don't know if there are external or internal entities polling these MIBs which can have certain negative outcome due to MIBs not found in the image.

Also, why are these SNMP error logs appearing in bgpd.log?
