Trusted Managers

By default, the agent accepts get and set requests from any IP address, as long as the
correct community string is used in the request. Security can be enhanced using the use of
Trusted Managers. A Trusted Manager is an IP address from which the SNMP Agent
accepts and processes get and set requests. An EM can be used to configure up to five
Trusted Managers.
If Trusted Managers are defined, all community strings work from all Trusted
Managers. That is, there is no way to associate a community string with particular
trusted managers.
