Issue/Introduction

After upgrade, NFA stopped to poll multiple devices though device is not in 'RebootRefresh' State.

Environment

NFA - 24.3.x

Cause

snmpretries, snmptimeout, and snmpmaxrepetitions are randomly set to 0, verify it as

select routerid, inet6_ntoa(router), pollstate, snmpversion, snmpretries, snmptimeout, snmpmaxrepetitions from routers;

Resolution

Login to Harvester DB from NFA Harvester server, run following queries:

1. update routers set SnmpRetries=2;
2. update routers set SnmpTimeout=3;
3. update routers set SnmpMaxRepetitions=10;
4. update routers set snmpport=161;
5. update routers set pollState='InitialPoll', stateretry=0, reboottime=0 where pollstate !='mapped';

After this, NFA would start to poll the devices.
