Community strings and sender addresses

You can explicitly preconfigure the IP addresses of the authorized management platforms. In this way, you force the SNMP agent to only accept SNMP requests from these systems.

The management platforms must have fixed IP addresses to do this. It is not possible to dynamically assign them with the Dynamic Host Configuration Protocol (DHCP).

Recommendation

Check the sender addresses of the management platforms by configuring their IP addresses in the SNMP agent.
