Troubleshooting SNMP Polling
Please refer to SNMP Polling and Traps section of NFO Administration Guide for details on configuring SNMP polling.
Check if you see syslogs with nfc_id=20003 in your system that receives NFO output. If you don’t see these records make sure there is no firewall between NFO and your network devices that may prevent SNMP traffic.
You can also use snmpwalk from NFO machine to test connectivity and make sure your network devices respond to SNMP polling.
If you don’t have net-snmp on NFO machine, please perform the following:
$ yum -y install net-snmp net-snmp-utils
Run snmpwalk to test
Example for SNMP v2c:
$ snmpwalk -v 2c -c public 10.0.0.1
Where “public” is a community string and 10.0.0.1 is your network device management IP.
This command will perform SNMP polling of all OIDs available at device 10.0.0.1
Example for SNMP v3:
snmpwalk -v3 -l authPriv -u snmp-poller -a SHA -A "PASSWORD1" -x AES -X "PASSWORD1" 10.10.60.50
