Explanation:
The best current practices recommend applying Access Control Lists (ACLs) to community strings and ensuring that the requests community strings are not identical to notifications community strings. Access lists provide further protection when used in combination with other protective measures.
This example sets up ACL to community string:
access-list 1 permit 1.1.1.1 snmp-server community string1 ro 1 A key feature of SNMP is the ability to generate notifications from an SNMP agent. These notifications do not require that requests be sent from the SNMP manager. Unsolicited (asynchronous) notifications can be generated as traps or inform requests. Traps are messages alerting the SNMP manager to a condition on the network. Inform requests (informs) are traps that include a request for confirmation of receipt from the SNMP manager. Notifications can indicate improper user authentication, restarts, the closing of a connection, loss of connection to a neighbor router, or other significant events.
