SNMPv1 and SNMPv2c requests can be validated against per-snmp-community allowlists (src-access-list) of configured source IPv4 and IPv6 addresses. Source IP address lists can be configured and then associated with an SNMP community.
SNMPv1 and SNMPv2c requests that fail the source IP address and community validation checks are discarded and are logged as SNMP event 2003 authenticationFailure (suppressed by default under ‟event-control”).
