snmp Centos 7 error

No-response is typical when the authentication is incorrect. Since the difference between SNMP v2 and SNMP v3c is authentication, then that seems to confirm it. [SNMP v3c works on a quite-different authentication model with usernames, not just community strings.](https://www.reddit.com/r/ccna/comments/dkrng6/snmp_v3_vs_snmp_v2v1/)

Check the logs on the host for messages from `snmpd`.
